Pretty well all the Equipment we talk about in "good stuff". After we buy it is a poor time to talk about what we shouls stay away from.
I 'll start with ammo you can get here in Nova Scotia. PMC(Precision Made Cartridge) used to be Pan Metal Corporation.. I took a friend 308 to the range and couldn't get a four inch group at 100 yrs with this stuff. A box )of whatever it was( I think maybe Winchester ) really tightend the group.
Imperial ammo, I beleive Canadian only, was just about as bad.
ChesterGolf will know where I'm comming from.
