Newbie Questions

1. How tight do you tighten the shell plate retaining bolt? I've read they can snap off. I don't want to over tighten.

2. I'm getting brass shavings what looks like on the crimping station. My crimp measurements seem ok. Is it too much flare?

I'll start off by saying I'm new to reloading. I've only loaded about 300 rounds. The indexing was off last night a bit causing primer issues. That's when I noticed the shell plate was super loose and causing the issue. I took it off and saw some shavings at the crimping station. Any tips for a newbie would be helpful.

RE: Newbie Questions

It's a shoulder bolt. Just make sure it's snug, but don't stand on it. What bullet are you using? Shavings are normally from too much bell, then too much crimp. Only the slightest amount of bell, just enough to set the bullet on the case, not it, the press will seat it, and just enough de-bell (crimp) to pass a case gage. Then plunk test in your gun. Crimp does not hold the bullet in place, in fact over crimping can cause set back and higher pressure. Neck tension (difference in bullet OD and case ID that causes the interference fit) holds it in. Dillon will be along shortly also.

RE: Newbie Questions

Canadianshooter,
We recommend flaring the case mouth between .010" -.020" larger than the sized, unflared case mouth measures. If using plated or polymer coated bullets, aim for .020". For hardcast or jacketed bullets, .010" is fine.
For crimping, look at the case mouth dimension in your loading manual. This will be the maximum. We suggest crimping to .001-.003" smaller than this maximum dimension.

RE: Newbie Questions

I've reduced my flare to .01 it was at .02. I've made sure my crimp is to load data spec. I'm still getting quite a bit of brass shavings. Is there anything else I can do?

Shavings after 100 rounds or so.
