Try getting a 44 special or something!2 cases large pistol primers
Let’s keep in touchdon't know
My 7x57 is a sporterized Chilean Mauser, my 6.5x55 is a new manufacture Zastava rifle with the modern 6.5x55 SE Caliber designation. Not sure what SE actually means, but rifles with these designations are designed to take higher pressures than the old two lug Military Mausers. Ballistically, the SE out performs the 6.5 Creedmore by a couple hundred FPS. These two calibers are not so popular in Canada, and are even less popular in the US, but in Europe these two are the most popular hunting rounds. 7x55 is good for pretty much anything. At the time I bought it, about 40 years ago, where I live (Southern Ontario) had a caliber limit for hunting of .280, so 7mm was OK. Because of the denser population and the increasing popularity of 7mm wildcats and magnums, the government lowered the Caliber limit to .270; 6.5x55 is .264; flat shooting and profoundly accurate due to it's high Ballistic Coefficient; and loadable for everything from groundhog sized varmints to Moose and Bear. IMO as perfect an "all round" cartridge as you can get. Regarding your primers; advertise on Gun Post or some other forum. I hear primers are in short supply in the US right now.A couple old military calibers, 6.5x55 and 7x57, do you like old stuff?
Also, I wish I could get some large pistol primers to someone who needed them, don't see my self doing much with them anymore
