All good info. Due to the claimed "stickiness" of the E-tip and the lack of +P H4350 data for this combo I'll start around 43 grains of H4350 and work up .5 grains at a time to 46 grains and see what the chronograph says while checking for any pressure signs. I'm looking for ~ 3000 fps or a little more. 22" barrel. I'm hoping to high heaven I don't have to go thru 400 bullets to hit pay dirt. I've made the bullet companies quite wealthy while trying to get the stock barrel to shoot. I did order the barrel with a 1:9 twist with monometal bullets in mind.
