Steve Timm turned me onto the 120 grain H4350 load when I built my .280AI.

I am running 61.0 grains (Near Max. so work up to it slowly) of H4350 with the 120 grain Nosler BT, Federal 215 primers, and fireformed RP brass. I get 3323 fps out of a 23 inch barrel and sub 1/2 inch groups.

The 120 Bt flat lays deer out.


That load in my 24" rifle clocks 3370 fps. I use WW nickel brass and CCI200's. Accuracy is good, but my 9-twist rifle prefers the heavier bullets. The 120 V-Max and B.Tip will do 3/4", the 140's and 150's will go half-inch or better.

Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!
