[msturm]

I have never shot tubes. I have been shooting 1 1/4 inch straight cuts in both TBG and .76 green GZK. I go with 1 and 1/4 because that is how wide my ruler is. It makes things simple. I shoot marbles .45 lead and .50 stainless out of them. They are a bit overpowered for marbles and I get some hand slap but it is worth is when that thwack lands on meat and I know that animal is going to drop! Im heading out tomorrow looking for some mallards that have been loitering on a pond near my house... Fingers crossed this heavy small ammo lands where I point it!
