I managed to scrounge enough to get 256 cases that were actually usable and found that the Win cases had large rifle primers and Rem uses small rifle primers. I haven't sorted through all of them yet, but I think CCI and the mil stuff is also large as well. Just curious as to why.

Also, while sorting a bunch of .38/357 cases I came across 21 cases headstamped WW then .351ww and sp or sl. Now what does that fit :confused::confused::confused: I think I also tossed some into my .30 carbine bag but haven't sorted those yet.

.351win SL. The sl stands for self loading. A fairly popular cartridge from the early 20th century. A lot of prisons used them.

Not sure why they use the LR primers,Rem. is supposedly switching over to LR primer in the 7.62 x 39mm brass also,at least thats what a gentlemen from Blue Star C & B said.

Save the Winchester LR brass you want have to wait to much longer Rem. is switching over to LR primer in the 7.62 x 39mm brass also,at least thats what a gentlemen from Blue Star C & B said.

NOOOOOOO! say it ain't so:eek:

why does everyone think it takes a LR primer to light a platry 30 grains of powder?

how many small primed cases ya got? if the price is right I'll buy em.:D

I have some brass ordered from Blue Star. They didn't have any packaged and ready to go but did get some in and are sorting through it. They also said Remington was switching to the LR primer. Not sure what I'll receive, but what ever it is, I hope it has the same sized primer for the lot.

So that explains it! I picked up a couple dozen of those at the range and only after I cleaned them up did I notice they were SR. Kept 'em separate and figure I'll use 'em sometime.

I don't have a lot of LR cases but I'll count em and see how many I got. They'll be KP stamped Lapua

Hey krochus, I still have a bunch of Rem brass if you still want it. I'll trade you KP for Rem or I can sell you the whole lot.

I shoot only RP 7.62x39 brass. Anyone that wants to trade large primer brass for RP can drop me a PM and we'll work a swap. :)
