I always use a gas check and an alloy that is hard enough for the velocity. Usually add some super hard to Wheel Weight alloy and water drop them from the mold for rifle ammo and size them to the stated caliber after coating rather than oversize to the stated caliber. You can shoot PC bullets like this to higher velocities with little to no leading but still not to what you would jacketed bullets.
Folks I am trying to shoot a NOE 260 118rf in a Remington 700 .25-06. This NOE design is a plane base design so NO gas check.
I found that the RCBS .25-06 seating die is squeezing my bullet down from .261+ to .257. I am trying to prevent this sizing down by heat treating the bullet. I am currently waiting for the quenched bullets to harden up to see if this will cure the problem.
It's all chicken, even the beak!
You might try a 260 Rem or 6.5 Creedmoor die for seating. The crimp portion of your 25-06 seating die might be sizing the boolits down is why I suggested the 260/6.5 seating die.
I'd trust gas check and good lube over paint any day.. Heck.. you could gas check..paint it AND lube it and get whatever magical benefits happen with the paint.. plus the proven stuff for the lube and gas check. As for your setup..it's apparrent that the rifling and or combionation of the components is allowing your paint to fail..if you even are painting the base. Perhaps try the paint and a gas check...
Perhaps you missed the fact that this bullet is PLAIN BASED and thus there is no room for a gas check!Originally Posted by Soundguy

I think that a 260 Rem seat die could be an option to try, or maybe try my .250 Sav seat die. It may not squeeze as much!
I wish I had a 260 Rem die.

Hardening up your alloy as you describe could be enough to stop the swaging.
Due to the price of primers, warning shots will no longer be given!
You are spot on. Hardening from Saeco 7 to Saeco 10 did the trick. My bullets are now the same diameter as pulled from a seated round as they were before being seated.
Now I have to see how they shoot!

That's why there are plain base gas checks. I missed nothing. You can get the thin aluminum ones from Sage's
Perhaps before telling someone they missed something..you do some research!
This is how we do it as well...

Very much agreed.
