Body die
I have a few 17 Mach IV cases that chamber a little hard (takes more effort the close bolt). I tried using the full length die to bump the should back a little but they still close hard. Should look into getting a body die?

17 mk4
might also check brass length.

+1 on the length, plus check the size near the bottom, have had a few that I had to hit with a small base die before.

The case length is fine (1.395). From what I've been reading, I could possibly use a bushing FL die or bump die to push the shoulder back a few thousandth. I use Wilson dies so I don't see spending the money for a FL bushing die. I guess ordering the bump/body die makes more sense.

Body Die
Phillip, Correct me if wrong, but would not the Wilson sizing die, if it is down and touching the shell holder, on the upper stroke of your press, be also pushing the shoulder back the amount you are looking for ? Bill K

My Wilson bushing die only resizes the neck.

I have a cold right now, so maybe the brain is not functioning like it should...
In post #1, it sounds like you are FL sizing. In post #7, you state that a neck die is being used. If your brass length is good, the first thing to try is bumping the shoulder back. A neck-only die will not do that for you. |

If you have a .223 Rem, .222 Rem, .221FB full length sizing die on hand, you might try taking the guts out of the die and running your cases up in any of those. I think a .223 small base would work for sure, but the others might as well.
When I had this situation arise with any of the calibers I've toyed with, the problem was more with the base of the case than the shoulder. but I would never say that's an absolute. |
