Some of you have probably already seen this stuff but for those of you that haven't....
Most 7.63 Mauser ammo is extremely expensive. This stuff is dirt cheap

I have never dealt with the company that is selling it but for the price, if you have one of those old Broom handles or whatever else may have shot this 7.63 Mauser ammo you may wanna give it a try?
