Seating die leaving rings on vmax

[satchamo]

I got a cheaper set of RCBS dies for 22-250 and I’m loading up 50 grain vmax in Lapua brass. I ran a .222 mandrel in them and chamfered/deburred but when I seat I’m getting ring on the bullets. They aren’t terrible but they are triggering my OCD. I tried the lapping compound on a bullet in a drill trick on the seating stem but it didn’t seem to make much of a difference.

I was going to just order a new die set from Forster/Hornady/Redding but wanted to check with the group and see if anyone has first hand experience with seating does that DONT leave rings on vmax in a 250?

Are you able to catch the ring on your fingernail? If not I don't think I'd worry about it. My forster seating die leaves a ring on the 223 rounds I load and my fingernail doesn't catch so I don't worry about it. I do know that forster will customize a seating stem for you if need be.

I have several dies that do the same thing. Doesn’t seem to effect accuracy.

mandrel with some wet lube and dry tumble for an hour or 2.

You probably have a friction problem, not a neck ID issue.

Last resort maybe try a dremel and polish the inside. I have done it on a couple and helps a little bit

I had the same issue with 140s Vmax in a 6.5 Creedmoor. The regular Redding seating stem produced a significant groove in the bullet. I think these bullet jackets are soft and unsupported at that point. I called Redding and the customer service guy said that they sell a VLD seating stem to the tune of $ sixty some dollars that would solve the problem. Think i'll wait to see how well the rifle shoots before I make that "investment".

That must be list price, they can be had for about half that.

New brass is very sticky, they will probably be better after firing.
I dip projectiles in graphite for new brass

Good point - I have some graphite so I’ll try this

See if RCBS has a VLD seating stem for that die.

If it's virgin brass, I'm with Lawnboi and Castle Rock. I wouldn't do anything about it until it's been fired and you've loaded a second firing on brass with carbon in the necks. It very well might go away if you dont clean all that carbon off with stainless pins or other intense brass cleaning.

like BBob said, they go for $30 typically.

All you need is a VLD seating stem

For Better Bullet Seating — Try Lapping Inside of Seating Stems « Daily Bulletin

Here's a simple task you can do that will give your seater die a more perfect fit to your match bullets. You can lap the inside of the seater stem so that it matches the exact profile of the bullet. This spreads out the seating force over a larger area of the bullet jacket.

Here is a bullet comparison pic of before/after, spinning a VLD chamfer tool in the seating cup. And the vld chamfer tool compared to a normal one.....

Looks like you have found the solution.

Can you feel the ring with your fingernail, etc?
