Thread: 223 on deer

Hi Tahr I've got a couple of questions.
Which Hammers are you using and in what grain weight? What's the minimum expanding velocity?

Im using 60 grain Hammer Hunters out of a 20" 1:9 barrel. 20 thou off lands. I used max book charge from hornady data for 27 grns CFE223 powder and 60 grain bullet. 3,100 fps. No pressure signs.
Recommended minimum velocity is 1,800 fps. That equates to 475 yards with my load. See this: There is a comment from the the owner of Hammer. https://www.longrangehunting.com/thr...locity.273925/

I have also played with (still playing) 52 grn Hammer Hunters and 26.5 grns BM2. Not grouping with first try so will push the projectile out from 2.3" OAL to the 20 thou off lands and drop the powder charge a fraction (slight flattening of the primer).

Its a damned expensive way to kill deer seeming the cup and core bullets work so well. But I enjoy the mucking around. They will stay in the mix and I will leave my M7 sighted in for them - I have 2 other .223's sighted in for other stuff
