I own a Beartooth magnum but mine is a 45cal. It also has scope.
I found that mine will pattern best with 2-50gr.-777 pellets and
the 195gr. powerbelt aero-tip. I did not try the loose powder because
I got such great results with the 777 pellets. And I would not
attempt a 150gr. charge with the Spanish barrel. But like I said
mine shoots great, its easy to clean and I like it an awful lot.
So I would appreciate it if you would post your results. And thanks
for your kind statement about the users here.
