As luck would have it I turned up Tony Rumore and he hooked me up with 5 pages of load data for the 40 Super for me to start with.

 

My .40 Super is a Springfield .45 Super with a .40 Super Barsto barrel with a full profile 3 port comp. I use a 24# recoli spring. The barrel is a standard non-ramped design and this is the weak point in my set up.
I contacted Tony sometime ago and got some 14 plus pages of load data he used in the development of the cartridge. His data is pretty close but individual differences from one gun to the next must be considered. My non-ramped barrel keeps me from realizing the full potential of the cartridge. I start to see the brass buldge in this unsupported area if pressures get to high.
I also cannelure all my bullets to allow me to Taper Crimp each round to help prevent bullet setback during the recoil / feed cycle.
Tony was able to achieve 1800 fps with 135gr JHPs. I maxed out at 1745 fps using AA#9. Once I saw brass buldging I backed off. To save brass and my health, I load at 19.5grs AA#9 instead of the 20.5 listed as max. I get good groups (1.5") at 1670 fps and can still use the brass. 1.250"oal
Blue Dot is also good but produces a lot of flash.
There was no load data for 155gr bullets but I have a favorite using a 155gr XTP on top of 15.3grs of AA#7. I use a Fed 200 to touch it off and keep Max OAL to 1.270". This load is by no means maxed out , but it yields 1490fps with a SD of 6. Groups are in the 1 inch range off the bench at 25 yards. I'm happy.

There are 3 pages that Tony sent that summarize his load development. The bullet weights are 135, 165, and 200.
Maximum velocities are 1700, 1600, and 1400 fps respectively. Is this the data you have?

I'm wishing for an STI Eagle in 40 Super. This is one hot round that is going unnoticed.

 

I wrote to STI asking for any info they had on the pistols they built, but as everyone already knows they stopped making them at all, not even parts from what they told me.

My growing pistol is a scratch build, Caspian frame/long slide and a 6" KKM ramped barrel. Since I am going with the long slide I may have it magna ported after I get to do some testing with it. This is my first venture with the 40 Super, so I'll see how it all works once I get to work with some loads.

Thanks for the tip on the 155gr loads, I didn't get anything from him for 155, and that is more or less a general purpose bullet for me, I have several 10mm and 40S&W pistols already. I'll have to look at the data that Tony sent, but I think there was a little on 180gr bullets too.

How is your pistol for handling, easy double taps or is it a handfull?

 

MP5KA1: I forgot to ask, what dies are you using? All I can find at the moment is steel dies from Redding. I would like a set of carbide if I can get my hands on some.

 

The Dies I use are Redding Steel also. I use some Hornady One shot on the Brass. I have found after 28 years of reloading that this is the best current bullet lube. Not messy, quick drying, and won't adversely affect your powder and primers. I use an old cookie sheet and spread the brass on it, spray on the lube, (it dries in about 2 minutes) and start reloading. Occasionally you will need to clean the dies ( 500 rounds or so ) to get build up out, but this can also depend on how clean your brass is before you resize.

If you find data ob the 180 Grain bullets, let me know. I have developed some 180 loads, but I haven't found one that reaches the accuracy and low SD numbers like the previously mentioned 155 Grain load.

I will probably end up buying an STI and rebarreling it with a Bar Sto. I too had communication with Jay at STI. They don't seem interested in building a .40 Super. Business is too good for them on standard offerings right now. 8)

 

OH, forgot to mention, double taps are a breeze, The comp and 24# recoil spring make it easier to handle that shooting 45 acp hardball in a non comped comfiguration. It's very easy to stay on target and just keep hammering.

 

40 Super is My favorite round for the 19 11, all things considered....I won't print any loadin's I use but I'll tell Yaw'll this, 180gr. bullets can be loaded to 1800 fps, tryin' to get past 1800 fps, PRIMERS GO TO HELL FAST......I've had the primers lock the firein' pin out by oozein' around and into the firein'pin hole....the 40 Super can run with the 41mag

Hey brother, I know this post is super old. Was wondering if I I could get that load data somehow? I've been loading 40 Super for a while but not that hot lol. Didn't know the brass could take that much. U using Starline? Thank you!!

 

Touching on this again.

Anyone know of any loads using Titegroup? Maybe even just a safe starting load, with the 155grs.

 

40 SWuper load data

I just finished a 40 super on a 1911 platform using the Storm Lake kit. I sure could use some data for 155gr projectiles

 

I'm happy to see there is still interest in the .40 Super after all these years.

 

Yes, I have a 45 Super on a SA 1911 and it's just a matter of swapping the barrel, bushing and spring out. I use a 32# for the 45 and a 24# for the 40

DoubleTap cases have large primer pukas and Starline has the small one which I use a small rifle primer.
I don't have much load/ballistic data for the Starline cases as of yet.

 

The .40 Super was intended to have a small primer pocket. In our development stage of the cartridge, we had way too may issues with primer flow when using a large pistol primer pocket. This happened even with loads that were not at the max pressure levels. When we went with the small primer pocket, this allowed us to run small rifle primers. Primer flow issues went away then.

Starline Brass was the company that worked with us in developing the .40 Super brass. I can't speak for any other company's cartridge case.

There is some good info on the .40 Super HERE.

 

I haven' had time to dig up My notes on the 40 Super , but , I think the powder I had the best results with was Lil Gun....loads were compressed loads...Small rifle primers , best I remember magnum primers seem to flow at about the same loadin as standard......45 Super , 40 Super , are nothin new , cut off 270 cases to .997 ,,,ream to hold the 45 bullet , that's the real 45 Super....Again primers will always limit how fast You can go....Same 270 case necked to hold the 40 bullet is the 40 Super....I know this has been done since the 1940s so it is DAMM SURE nothin new

There is very little new in modern cartridge designs. Only improvements on old concepts. That is a given. The major step forward is when a cartridge like the .45 Super or the .40 Super can be bought in the store because of being factory loaded. Now it's no longer a wildcat and many variables have been eliminated.

 

I've never seen a 40 Super in a store , not sayin They ain't there , maybe They hadn't made it to North Louisisana yet....I bought Starline Brass , that is a given But if I buy the loaded rds How do I know They are loaded as HOT as I can load them , If They arn't Hot as They can be run whats the use of havein' a 40 Super , might as well stay with the 10MM

Since You mention " Our Development Stage " by stressin "OUR" , maybe We can get back to the OPs question , "for good safe load info"....My load data is good for the way I set a pistol up to run with HOT loads , I'm not sure how safe it is in other 1911s

The .40 Super started its life around 1999 as a factory loaded cartridge. Triton Cartridge (the company I founded) developed the .40 Super with assistance from Tom Burczynski and marketed versions in the Quik-Shok line as well as the Hi-Vel and even the CQ Frangible loading. At one time there were seven factory loadings of the cartridge. Production ceased in 2002.

Factory loads were able to achieve 1,800 fps with the 135 grain JHP, 1,500 fps with the 165 grain JHP, and 1,300 fps with the 200 grain JHP. This was achieved using commercial powders. Load development was done with a strict adherence to pressure testing.

Can higher velocities be achieved with the .40 Super? Yes. However, because we were producing factory ammo we could not control the idiot factor. Thus we did not push the ammo to the limit. If someone is using a barrel with an unsupported chamber, the factory loads are as fast as you want to go. If you have a barrel with an integral feed ramp and greater support of the case walls, then 2,000 fps can be achieved with the 135 grain load. I did that with S&W 4506 during load development.

All this is predicated on using Starline produced .40 Super brass. If any other rifle case is used to create a .40 Super wildcat, then there will be differences in case wall thickness, case web thickness, etc. Without pressure testing loads in that type of brass, I cannot say it is a safe approach.

 

Fernando....man, it's been a long time. I still use that 40 Super that Niemer built for me back in '98 for hog hunting.

The 40 Super seems to be getting some legs lately. I have been getting a lot more requests for my load data in the last 6 months than ever before.

I'm got a 40 Super barrel and need some dies and reloading data,is there some updates as to where I can get some? A website to go to?
What brass is the best to form? Starline makes new but it may take a year or two before they even run some,right now I've got 100 Double Tap loads that I can get brass from but it will get pricy to keep buying those just to get brass to reload.Any help would be apreciated.

 

I have just ordered a 40 super barrel for my springfield longslide. I haven't recieved it yet. I am also looking for as much info on handloads too. I ordered brass from starline with no idea when delivery might take place. To date I have found Doubletap and Load-x ammo for sale. I also found brass at Midway. I bought a set of Redding dies there two.


I hope the 40 super takes off again, maybe if it were called the "40 mag"?

 

Isn't the 10mm Auto the REAL .40 super?

 

I really wanted an auto in a .40, something that could be hunted with. I have noticed there is a bit of reluctance by the 10mm people to give credance to the super 40. Not sure why that is. I have yet to shoot the super, waiting on a barrel for my 1911, but all the articles I have read only leave me to wanting the super 40. The 10mm was a close second or third though. The 41 mag looked interesting also, but the balistics of the super won the day for me.

 

I have some load info on the round,I'm going to write my own for the rest.
I ordered 1000 cases from Starline and the lady estimated March before they make the brass again,they need 25,000 on order(they had 6,000 currently).
For the time being I bought 2 boxes ofr Double Tap ammo for the brass,will probably get 1 or 2 more by January(depends what the order total at Starline is by then).Someone needs to order 15,000 pcs. soon.
I think for some reason the 10mm guys feel "threatened" or whatever (hurt ego maybe?)because they'er not the only powerful 10. Just dumb! Who cares if there is another 10, I wouldn't care if someone releases a bigger 10mm then even these two,it just doesn't matter ,another option.
My barrel from Storm Lake took almost two weeks longer than it should have because they made the wrong barrel. I called them to send it back,they wouldn't start on the right barrel until they got my barrel back ,then put it "on the list again.That is BAD business.When I informed them of their mistake ,they should have started on my new one imediately so when they recieved the wrong one back,the correct one could be sent out that day,not put at the end of the list again after they got mine back.

 

Storm Lake barrels were the lower price barrels when I started doin business with them a long time back...lookin at Their web site now They may be the highest priced...I haven't bought a barrel from anyone in three years or more so I can't say...First 40 Super barrels I bought from them , I had a HELLOFA TIME gettin them to understand the Chamber End or Barrel Hood if You prefer had to be 45 Deminsions (outside) with a started chamber (45) (short ) of 1/2 in depth....Guess what I'm tryin to get across for those of You that haven't worked with the 40Super is a 40 Super barrel needs to be a 45 barrel (hood width ) on the outside , 40 caliber bore...There may be 40 Super barrels out there of different configurations , alll I know is when We started HOTTRODDIN 1911s We sleeved 45 barrels to 40 , cut off rifle brass to make cases.....granted You can weld up the barrel hood on 40 cal barrels , and probably be safe , maybe, I doubt very much pressure gets outside the case

ya ,the 40 slide is narrower at the hood cutout than the 45. I am asuming they know that by now.Unfortunately I don't know of any other barrel maker that makes a 40 Super barrel. Maybe some smaller guy does somewhere,but none that I have found through extensive searching.Looks like I'll be waiting till Jan(I called today and they said end of next week before they even finish it,so basically they haven't even started it yet).If I could find another option, I'd tell em to shove-it.

 

I had Fusion make my barrel, it was an inch too long and wont drop into my springfield longslide. It will need some special attention to fit. Fusion said to open up the bushing but I don't believe that will fix it, only wreck the bushing. I will be sending the barrel back to get it cut down and either send the gun and have it fit or just have them make me one of their semi customs with that barrel. I also ordered 2000 thousand cases from starline 2 months ago. Bob at fusion is good to work with so far, always answers the phone or email promptly.

 

40Super Data

I am hoping you were able to locate some data, if so please contact me, I would very much appreciate getting some data.
