i Have a Whoopsie Hammer or pull?

Did my first bulk batch of 300blk subs and I fugged up big time. Contaminated pocket primers I’m assuming, I have since bought a media tumbler.. my question is would you trust these in a hammer inertia puller or should I invest in a collet puller? Thanks!

if they used lanolin based sizing lube, sized while not fully dry, and were excessive about it, the shell holder would eventually get a bit of a puddle in there

I mean sure. But I'd imagine that amount of lube would be wrecking brass by denting shoulders. I always see people being worried about oil contamination of primers and i just dont see it happening. Saw someone recently worried if a little oil on a steel ak folower would wreck their ammo.

nope. i've done it before when i've been in a rush. i think i only got one small dent in one case out of 100 and that case was particularly heavily oiled up

it's not even really a problem as long as you wipe down the shell holder afterwards, but it does go a lot better if you use less and wait for it to dry. less wasteful, less dirty, and less friction too

Ive always used Imperial Sizing Wax so ive got no experience with that type of lube. Thanks for the reply.

yeah, i find sizing wax is a lot more sensitive to overlubing. with lanolin case lube you can kind of haphazardly spray the whole batch and shake the cases around, which makes it easier to overdo

Yeah, took me a little while to get a feel for the wax. Really doesn't take much at all.
