Yes they sure do have rules on 7.62 and rifle cartidges in general. No steel cased ammo. Yes I know it should be steel core ammo but they do not like steel cased ammo either. Last time I was there a guy brought his daughter, his AK, his 500, and some sort of pistol which I do not recall. Any, he quickly ended up only shooting the pistol and shotgun because the range officer confiscated his wolf ammo.
For brass cased stuff they sell cheetah for 11 bucks per 40rds downstairs. Which is still about 5 bucks better than the value pack at walmart.
