Had an opportunity to buy theur bullets and primers about 7 yrs ago and there were no problems.I've used their brass in 243, 7-08, and 7mm mag. Heavy brass for sure. I've found it good to fully prep primer pockets and flash holes.
I pulled some bullets on PPU loaded ammo. They heavily tar seal (for lack of the proper description) the bullet into the neck of the cartridge. I find pulling the bullets the pressure required can vary considerably from cartridge to cartridge. loaded ammo aside, the brass quality I find acceptable. More so now than in the past!!
Graf & Sons is a good source; that is where I get mine, but like everyone else the pickings are slim right now.They are in Serbia. Where can you order their brass?
