Peterson Brass

[SVT_Tactical]

Read a few places that Peterson brass was ready to load out the bag. And I've also read that there have been lots of brass with residual lube from manufacturing that can foul powder. I've always ran through my die with appropriate bushing however i have never ran virgin brass through the cleaner before loading. Do y'all clean brass prior?

I’ve purchased several hundred pieces from them over the past two years and have yet to note any issues with cleanliness as the cases are removed from their boxes.

I turn necks and clean cases afterwards to remove the lube I applied.

 

[Darkside]

NO. Size the neck, check o.a.l. proceed accordingly.

So far I have not seen any residue in the Peterson brass that I have used. The only issue I have encountered is the load must be reduced from a Lapua brass load. Especially the small rifle primer brass which weighs @ 10 grains more than 308 family Lapua brass. Smaller brass like the 6BR family the weight was almost as much difference.

I had a few that didn’t fire and am wondering if oil fouled the primer or powder.
They were false shouldered and significant bullet jam so headspace wasn’t an issue.
I’ll dip the next batch of new cases in acetone first

I did segregate those primers, to test later.

I always FL size and mandrel new brass. Probably over-kill, but I'm convinced it makes the data from that first firing much more useful.

I've bought Peterson brass on several occasions (some from bulk bags and other from their boxes of 50) and never had any that needed to be cleaned before use. But there are other issues for considering. Peterson brass most likely will have a different case capacity than other brass I use as I've found every time as well as different primer pocket depths. The brass is nicely annealed and trim length is very consistent, but the case mouths are not chamfered or deburred. The bulk brass has had just a couple cases there were slightly dented and rand a expander mandrel through them and the boxed cases have never had that issue due to the way they're packed. If any of these things are of no concern to you for their first firing, the brass is ready to load and fire.

If you buy ther brass in the 50 count ammo box its pretty much ready to go. But some companys buy it in bulk and bag it. Then you should treat it like any other bagged brass

I’ve had great luck with the 300 wm.

I didn’t need to clean the Peterson, but I did have to reduce my load from the lapua srp/Palma load I had been using.

 

[varget204]

Recently got 650 Peterson Cases 3 different Lots, ALL Cases .265 at base of Neck, .268 at Case Mouth,Case weight Varied 8 grains between the 3 , Have to FL Resize every case

 

[Fast14riot]

I've never had issues with any residual lube, it is less capacity than pretty much everything else out there. Ive also noticed primer pockets on SRP 260 brass are very tight with a larger radius in the bottom corners of the pocket that can make primers stand proud. I do uniform pockets and run a mandrel through the neck, but thats usually it.

A few months ago I purchased some Peterson brass and had some problems. That's another story. On the question of cleaning...While breaking down some of the brass that I had loaded there were lots of cases, (probably 15 cases) out of 25 that when I dumped out the powder there were many small clumps of powder. I thought maybe my powder had gone bad. I emptied out what was left in the 1 lb. can and it was fine, no clumps. I have used Peterson brass many times before and that was the first time powder clumping occurred.

I suppose you could swipe the inside with qtip before opening the necks and loading, to be sure. But I’ve never needed to.

If there is a chemical problem in the case, I wonder if a Qtip would really fix it?

It would show if there is residue. If I found residue of some kind I’d tumble it.

I noticed some powder sticking to the neck area on that virgin brass I loaded.

This is was my experience as well.
