Okay, I started this project a couple of years ago and got sidetracked.
I'm baaaaaack!
I have the Accurate mold 31-155W that Josh and Ian designed to fit this caliber. Thanks guys for the time and advice.
I'm powder coating this bullet and trying to use it to fire form brass. The lead is about a 12 Bhn. Casting the bullet, running it thru a .309 Lee push thru sizer after coating. Bullets are slightly out of round measuring .309 x .3095. I may have to get a .308 sizing die. I have about 500 of these. PC may not work on the final loading, but I'm trying to use what I have up.
I had a failure to feed stick in the chamber and had to tap it out from the muzzle.
I also have a Wilson chamber gauge, that I now use to check the loaded rounds.
The trouble I'm having is when loading, the neck on every 5th or 6th round is preventing the round from chambering.
The Hornady two die set that I bought from Wilson sizes the brass fine and all unloaded brass will chamber fine. The seating die does not taper crimp, but wants to roll crimp the brass. The neck at the mouth winds up being about .001" too large on the problem loaded rounds.
I don't have a ball caliper to check the neck thickness, but understand the design of the round allowed for the thicker neck brass due to forming the load from 223 or 5.56 brass. I'm using PPU brass.
I'm thinking that I need a taper crimp to smooth out the necks and let the round chamber, but this being a wildcat, not sure what taper crimp to buy.
Do any of you guys that shoot the 300BO taper crimp your rounds?
Trying to figure out if any .308 taper crimp will work or if, say a .308 Win. will be too deep to work with the 7.62.
Thoughts and advice will be greatly appreciated.
