I hate rifle case prep! My hands hurt..

[LRShooter]

I've prepped up around 2000 of the HXP cases. Without my RCBS case prep center and powered trimmer I'd of just kept buying it from the CMP.

I've done up a bunch of .223 as well and find them a little more irritating at times. Smaller case is harder to hold.

One of the big time savers was getting the three way cutters for the trimmer. They chamfer/deburr at the same time they trim. I pretty much only use the case prep center on primer pockets now.

I just chucked the brass into my cordless drill fingertight and used the chamfer tool to open primer crimp. Worked great takes 10 seconds per case. I have done couple thousand by hand over years.
