I've got a problem with my Kimber Pro Carry SLE that's driving me nuts. For the first 20-50 rounds it works great, but then it starts feeding erratically–the slide doesn't go fully into battery. All the rounds are drop-checked. The following has been done to the Kimber:
polished feed ramp, barrel chamber, breech face and underside of slide
installed Aftec extractor that is properly tuned (definitely made the feeding problem better)
throating was checked by a smith who said it was fine
the chamber seems okay since my reloads go kerplunk when dropped into it
I'm using CMC 10 rd. mags (same problem exists with Wilson 8-rounders)
18 pound Wolff spring (I'm reloading to IPSC PF–about 170 PF)
Precision 230 gr. RN bullets w/ 5.8 gr. VV 340 @ 1.245 OAL (I've tried different OAL's with the same problem). All reloads are crimped.
Does anybody have any ideas about could be causing the feeding problem? BTW, the spent brass ejects fine.
