Q: will this shoot lacquer wolf crap with out breaking the extractor?..... ahhh I mean ammo? Thanks!

Asked by: Tracy Ziemke - 6/14/2020

A: You can shoot anything; however, certain ammunition like Tula will shorten the life of bolts/extractors and cause premature failures. Extractors will break eventually in this caliber due to how thin the walls are machined and other things will contribute to a shorter extractor and/or bolt life like overgassing.
