Sierra 120 Tipped Gameking

Here is what I'm starting with for a quick hunting load.
28.8 grains of TAC (Sierra Max Load), Federal GM Match AR primers, Hornady Brass @ ~2.270"

Out of an 18" AR, this group averaged 2425 fps. I worked up to this one in about 70 degree weather. No signs of pressure and this one really tightened up compared to my others, but I was also feeling a bit off due to a large amount of wind which calmed down slightly during this group.

I'm loading 10 for a hunting trip next weekend to have some for testing terminal performance if the opportunity presents itself, but I don't want to load too many as I'd like to experiment with some more rounds to ensure that I didn't just get lucky with this group.

This is the info I was looking for. TAC has seemed to do the best for me out of gas guns. My chamber in my BCA is 2.281. That would give me .010 jump. My barrel is 2 inches shorter @ 16". Hoping to get my chrono out, but the wand may be busted on it. I can rough calculate 2375. This might be my hunting load, as long as while I am working up I show no pressure signs.

Shot one doe, but missed another with my 6.5 CR last weekend. In a ground blind, that 22" barrel and Magpul stock are like swinging a sword. Could not get my rifle in place to get the other doe and she was only 30 yards from the blind. I need a good load for my 16" BCA to maneuver better. Longest shots is about 200 yards, so that should be perfect.

Thank you.
