Gas checks ? are they to tight for my throats ?

[gray wolf]

I put some gas checks on Lyman #429244 bullets.
They were sized to .4315 --throats are .432
The bullet is a nice snug fit but the check needs the pressure from a pencil
to push it through the throat.
Will these screw up the throats when shot, will they stay on ?
Should I hold off till I can get a little smaller sizing die and re-size them.
They go through with a little push. The bottom of the check goes OK but the top half is the offender.
Should I anneal the gas checks, Or is all OK
Sorry I need to learn this revolver stuff.

They are alright. The brass GC has more "spring back" than the lead alloy which is why they are slightly larger. They will size down with out any problems in the throats and the forcing cone into the barrel. I seriously doubt if we could measure any increase in psi if we compared them to ones sized a thou or two smaller. Load'em and shoot'em.

AH--the old spring back thing, I for got about that, >>> thank you.
As long as they stay on for the trip out the barrel
and they don't mess up the throats, then down range they will go.

Kinda hard for them to come off in the gun with several tens of thousands of PSI pushing them against the boolit base.

Sounds like a nice fit to me.
