I was going to post this on the OAL thread, but I'm not sure it's an OAL problem... so probably better to start a thread. Here's my story. I have a preloved, low round count, 2015 build SVI with an AET barrel in .40. This is my first time to reload for .40 and have not had any issues with reloading 1000's of rounds in 9 or .45 in the past. I know the AET's have tight chambers, so jacketed .400 bullets are recommended per the builder. I had some .401 bayou 180s on hand and loaded some of those up first to test. A large percentage of those failed the plunk test. Even the ones that dropped in cleanly still required a bit of a shake to fall out of the barrel. I am using dillon seating and crimp dies with the lee U die for sizing, so my assumption was that this issue was related to the .401 bullets. I then ordered a case of .400 fmj 180's and loaded a test batch. They are better, but still not going in and out of the chamber or my .40L hundo as easily as I think they should be. I'm now beginning to wonder if I am loading too long?? (1.19 oal) I'm at wits end with this. The brass itself plunks fine and case gauges easily after sizing, before loading. So I am relatively confident that it is not a "glock bulge" issue causing the problems. I have tried more bell, less bell, more crimp, less crimp, all to pretty much the same results. I have a lee FCD on the way that will hopefully fix the symptoms if all else fails, but I'd like to figure out what the actual problem is and fix that. I was hoping to shoot the gun in match last weekend, but concerns about my reloads are keeping me in production for the time being. Where do I start trying to trouble shoot this? Is it possible that the rounds are just too long at 1.19 and are sticking on the lands when I try to drop them back out of the barrel? Brandon at SV recommended 1.20 oal in the "recipe" he sent me. However, I don't see how going longer will address the issues I'm having. HALP?!?!!?!!!
