I opened a case of ammo today that I bought years ago. I knew it was 223 steel case but nothing on the box stated what gr.. Opened it and it's Golden Tiger 56 gr. FMJBT. Is there any difference between this and regular Wolf ammo? I've got 2,000 rounds of it and don't really need it. I can't find any for sale and nothing on GB. Anyone have any experience with it? Thanks
