The friend whos 308 I have been working with came over this morning with some brass from shooting to fire form for reloading. He purchased 3 boxes (60 rds) of reloaded ammo. All the box says is: 145 GR. $9.95 On firing he said most were hard to chamber and extract. About 6 had to be forceably extracted. He stated that they seemed hotter than the 180 gr Win and a lot more than the 150 gr core-lok. The brass is PPU. I checked the case length and all 40 cases where within specs. I then checked about half of the unfired box for OAL and all where 2.85 +/- 5/1000. Thats a little long for me and all reloading data I have (Lyman, Lee, Sierra). I advised him NOT to shoot any more of them. We called the reloader to get component data, Bullet, Powder, charge and primer, but he was not in today. I full length sized the cases , will reload and seat to 2.70 and seat Sierra 150 gr Game Kings, and have him refire to re-form. Without knowing the components and IF the cases had been full length sized prior to reloading really no way to make a best quess as to what went wrong. And they did have a slight crimp. Win, Rem (factory) AND MY REALOADS had no problems.
