Pistol brass prep

7887mm08

Silver $$ Contributor
So the other day i was prepping some new starline 45 acp brass.
When doing centerfire rifle ammo, i uniform the primer pockets.
Well after uniforming about 50 primer pockets (with a large rifle tool) i realized what i had just done.
Did i ruin this lot of brass or am i good to go? I have set these to the side for now.
MY load is middle of the road as far as powder weight is concerned.
Thanks for any help

Thats what i figured, just a habit i am used to doing for rifle reloading and carried it over accidently to the pistol.
Thanks
 
Just want to address the issue of uniforming primer pockets for pistol cases.

I've loaded thousands of competition grade pistol cartridges and never uniformed primer pockets. I truly believe it adds nothing to the precision of the load.

I will go as far as to say that its best not to do it especially for defensive rounds because of the chance of cutting too deep even with the correct uniformer and potentially creating misfires.
 
Again i uniformed the pockets by accident, not by choice. The question asked was if the brass was ok or not. I have never uniformed my pistol brass before this incident and even if it made a difference I can guarantee you I wouldn't be able to tell! Haha. I'm Just a recreational loader and shooter making some plinking rounds.
Thanks again

I wouldn't sweat it, it's not like it's a real high pressure cartridge. You take a couple pins and put one in the pocket and one inside the case and use them to measure the thickness, if you don't have a caliper that can measure it. Then measure the length of the 2 pins and subtract.
Then measure untouched cases. I doubt it matters much.

Measure the new pocket depth to get a clear understanding of what you have. With differences in tooling versus SAAMI specs you may not have taken off very much brass. Compare new brass pocket depth to the modified brass depth.

Well, there are guys on Calguns (a California shooting forum) who are weighing and sorting brass, bullets, and primers for pistol loads. Not really sure why when normal pistol groups are on the order of, what, 10 - 20 MOA? To each their own though.

Personally, I feel a little anal as I clean my brass before loading (I'm shooting bullseye guns, which can be little finicky about contamination.) Other than that, I just pop them on the progressive and crank them out.

They put too much emphasis on minute details & not enough on training.

I'm not gonna cast any stones here. When I first started shooting Bullseye I weighed all my cast bullets to within 0.1 grain. The extreme weight spread (IIRC) was something like 2-3 grains (20+ yrs ago so memory may be off a bit) but the vast majority was within 1 grain. I quit doing that after reading a post by a Hawaiian gunsmith by the name of Ed Masaki. How he cleaned his mixture of brass with a cement mixer, used bulk cast bullets by a now defunct co (Western Nevada if memory servs), loaded everything on a progressive Dillon, and as long as the bullets were within 3.0 grains, they would all go into a 10 shot, 1 1/2" group at 50 yards. Yeah, His guns are that good. One of our local guys has one that he won't sell, can't say I blame him. If it were mine, I wouldn't either.

For sure - each to his own - if it makes you feel better go for it.

The only issue I was addressing was uniforming pockets on pistol cases.

I tumble clean cases and clean primer pockets after each firing.
