Which Bullet lube for 41 Swiss?

Post by KneverKnew »

I’m casting with the Lee 430-310 flat point mold using gas checks. I recently got an original RCBS Lubamatic Bullet sizer luber. The old box came with one tube each of RCBS Bullet Lube (for pistol?) and RCBS Rifle Bullet Lube. My precious loads with a similar purchased Bullet was doing around 1450-1500 FPS. My question is will the regular RCBS BULLET LUBE with a gas check installed, sized to .429, be adequate to prevent leading of my cast 310 grain bullets at those velocities? Or should I be using the rifle bullet lube?

I've had very good results with this Lube:

It is a direct replacement for the age old Red Rooster bullet lube that I've been using for decades.

Thanks. But I already have the two mentioned. Just need to know if the regular rcbs bullet lube will work as described.

If they are cast projectiles I'd have thought you'd use Alox in your swager your before final sizing.

I should explain what I meant by "final sizing".
We do case hardening on all of our cast projectiles, so when we slog the bore we order two swagers. The first one is 1000th over the slugged bore size and then after case hardening, we use the second swager which is 1000th under. Even with a 30 caliber projectile, we can easily push right up to commercial FMJ velocities.
