I have been loading the following recipe for the last 7000 rounds with no problems what so ever, for 5 different guns.
Win 115gr RN FMJ
Win 231 5.2grs ( I know this is high but it hasn't shown any signs of problems until now. It chrono at about 1180 when I first worked it up)
CCI 200 small pistol primers
Win brass ( range pick up, pre inspected by yours truly before loading)
OAL 1.20
Had a case failure with the following gun
Browning High Power 9mm Mark 3
Case failure was at the 6 Oclock position at the feed ramp. Damage was slight to none, still have to check things out completely tomorrow.
Of course the gun is not mine, but a friend who met me at the range, after haveing been to my reloading room to load up a 250 45acp rounds for some of his other guns. I have him load his own useing my equipment. Then it was off tho the range to shoot.
I have shot this same ammo out of my
Glock
Sig
Taurus
Smith + Wesson x 2
Kel Tec
( I was shooting a sig with the same lot of ammo right before this happened)
I have seen zero pressure signs, primers fine, spent brass fine, feeds fine, ejects fine, and accurate.
After the failure I checked out the other spent cases from that gun and they all were bulged from the unsupported feed ramp area. This was not the case for the other 9mm guns we were shooting with the same ammo.
I figure it one or a combination of issues,
to hot a load
bullet set back
unsupported chamber (I would like to hear from others that have this gun)
useing range brass
all the above
Thanks in advance for your thoughts.
