Well my favorite is the 13.43 gr pellets, but my Maverick now with a working barrel also shoot 10.34 gr and the even heavier beasts if you want smack power but not shoot more than 50 M / yards.
I haven't tested very many H&N pellets in the rifle CUZ my tin stacks with JSB and others are much taller and i dont feel like expanding collection too much if i can help it.
