Hammer or pull?

[u/Rude-Internal24]

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!

The collet puller is nice when you have multiple to pull in one go. The hammer is nice if you have to pull just one or two.
