Unofficial so far but trying out my first Hammer bullets. 35 grain .224 Hammer Hunters to try in Custom Oregunsmithing 22-250! Winchester CRF short stainless action, 22" fluted benchmark #2 I believe barrel. Pendleton Classic hunter stock. Haven't crono'd yet but started out a quiky for pressure using Varget. Worked from 38 grains up to 41 where I got just slight primer edge flattening, not out to the outside edge of primer. Bolt smooth as glass still and no case head bolt marks but I'll stop there as it's a full case of varget without taping it on bench. Looks to be 4 rounds 1 grain increments in one steel plate splatter mark at 200 yards!! Good start I think!!!!! Can't wait for deer season (oops I know it's not a deer caliber)!!!!!!
