Like your choices. Everyone always wants 00 or even 000 buckshot. #4 buck or BBs much better. Great coverage.
Is you 6.5 the 6.5 Swedish, 6.5 Grendel or ?
I want a 6.5 Grendel from Alexander Arms so bad.... it’s a .223 length round, fits into the M-16 form factor and magazine, and has more energy and less drift at 600 meters than a 7.62 NATO (.308 Winchester) round !
I don’t mess with the BB or any of that smaller stuff. If I’m going to shoot, I’m going to do it right, thus F or T-shot. If I’m feeling adventurous I buy the Coyote shot from Winchester, which is a little bigger than normal F-shot.
The Stevens 200 is a 6.5mm Remington - it doesn’t come in Grendel or any of that foreign crap. Problem is finding ammunition for it. Everyone in the States sells .30-06, but nothing in .25-06! It’s a great rifle, none-the-less.
