Bullet Seating Question for 300 Wby Mag

[DAN CARROLL]

I have an RCBS partner press and I use a RCBS reloading dies. The bullet seater die after I seat the bullet leaves a shallow ring around the bullet. I the bullet seater die will also crimp... does anyone know when the bullet is being seated if its leaving a crimp ring near the tip of the bullet. if this is the case any help on how to adjust the seater die would be greatly appreciated thank you.

It sounds like the seating stem is leaving that ring. This may be a sign that you are applying an excessive crimp. The die is crimping before the bullet is comletely seated and the stem is biting into the bullet.

Try backing the die out a bit and turning stem in the same distance.

It simply means the bullet seating stem does not match the bullet ogive profile you are using.

The seating stem may have a sharp edge inside it from manufacturing.
Sometimes it will help to take it out and polish it to a more smooth shape.

Barring that, RCBS will sell or make you a seating stem to match the bullet you are using.

BTW" I have made "custom" ones by "glass bedding" a bullet in the stem with JB-Weld.

Added: I agree with Shoney that you may have the die body set up to where it is trying to crimp. But I didn't think of that, he did!

Make sure you are inside chamfering the case mouths to allow the bullet base to start in easily.

any help on how to adjust the seater die

Can you intermix 215 Federal and CCI 250 M Primers

I generally use the fed 215 primers for my reloading recipes. But since I cannot find any can I use CCI 250 magnum primers instead? Also has any one seated live primers and used a decapper to remove them and then re- seated them in different casings?

DAN,
You can swap brands on the primers BUT you should back off on the powder charge some and work back up while watching for overpressure signs.

I've seen the topic discussed here and have even done it a few times myself, yes you can deprime a live primer and reuse it if it ain't damaged. You should be wearing your safety glasses anyway when you're reloading but in case you're not put some on. Use steady pressure when pushing the live primer out - no impact - ease it out. Just be careful it ain't that big of a deal. HTH.
