I have loaded some of these bullets. Here is my recipe
Now I haven't had a chance to hunt with them but do plan to give them a try this year.
I have a savage 110 270
Imr 4320 47 gr. Nosler ct ballistic tip 130 gr cci 200 primer fed casings
This load shoots 3/4 inch groups @ 200 yards
I tried this same load with fed 210 primer and the groups @ 200 yards was 1.75. So changing the primer made a difference in my gun.
