Hello all, I'm going to put it out front, I'm pretty green to reloading and casting. So far have only cast/loaded about 1600rnds combined of .40sw 9mm 10mm using Lee Dies and molds, and the Rock Chucker kit.
Now that that's out of the way, through some trades/deals with members here I've gotten set up to load .45acp (thanks Bullfrog and 300blk) using an RCBS die set and these .452 230 lrn boolits. If you look at the picture you'll notice small 'ridges' in the cases. They chamber fine in the gun i'll be using (Kimber Custom II) My question is what is causing this? Am I doing something wrong? The two cases on the far left are as they come out of the expander die, most are not this severe, these were same headstamp, I figure maybe it was just the brass. I set the expander die just low enough to open the mouth just enough to seat these bullets with out shaving material.
I set my size die as recommended (raise arm, screw die down to shell holder, lower arm, tighten additional 1/4turn, lock), and seat and crimp in separate steps. The OAL is 1.250 +/- .002, case mouth runs .469-.4705 od, web/base it around .475.
I've seen this "coke bottle effect" on a handful of 9mm cases I've reloaded and they've shot great so I didn't think much of it. I've not yet fired any of these rounds but i'm guessing they will also shoot just fine. Maybe this is just an asthetics thing and i'm being picky but I like to my reloads to look like factory loaded ammo. Just curious if anyone can tell me something i'm doing wrong here. Thanks in advance for any insight!
