I did some load testing today with my new Christensen Arms Ridgeline Scout .223. This rifle has a 1/8 twist 16" barrel. My best load was:

Sierra 77 grain TMK
IMR 8208 XBR 23.2 grains
CCI BR4 primers
Mixed brass
2.300" COAL

Max 2664
Min 2642
Avg 2649
SD 8.6
Here is another load test:

Sierra 77 grain TMK
RL 15.5 - 24.8 grains
CCI BR4 primers
Mixed brass 2.330" COAL

Max 2632
Min 2612
Avg 2625
SD 7.6

This load groups well. However, it is a compressed load. The seating die leaves a minor crease in the bullet ogive.

Mine from last week.
IMR 8208 XBR @ 23.5 grains,
CCI 400 Primer
2.26 COAL
77 GR TMK
ADI Brass

2564 FPS. Never measured, but 5 at MOA or just under at 100 yards with the Magneto Speed on the barrel. I would assume it would be at least as good if not a little better without the chrono on. This is a Ruger American Ranch with a 16” barrel. It’s slower than I had hoped, but I picked up 100 FPS over Varget. StrelokPro says 1806 FPS at 410 yards. It will work for me.

Are you using mtn tac magazines? I have liked the 73 eldm but the 75s are too long to use in the factory mag, playing with the 77 tmk now.

Yep, billet magazines.

SAFE IN MY GUN. DO NOT EXCEED PUBLISHED MAXIMUMS.

I’m getting right at 3100 fps at the muzzle. Accuracy ain’t bad. Top target is three shots, bottom target is 4 shots.

I love my .223's and find myself taking one instead of the more traditional deer calibers. They are low-recoiling, accurate, and will do their work as long as you do yours. Like folks mentioned, limit your shots to about 150 yds. or so, use a good bullet and concentrate on shot placement. Even better if you can shoot it suppressed.

Regarding the 77tmk in a 22 creed. I’m toying around the idea of buying a 16” 22 creed barrel being that I now have the equipment to swap around barrels. Wondering what you would consider a reasonable upper limit on impact velocity for up to deer? Also if you have any experience with real short 22 creeds. I think a 16” with a suppressor still pushing the 77 at 3000 fps would be pretty awesome.

I actually haven’t seen an upper limit per se. Even at 3,300fps impact that still penetrated enough and caused very large wounds. You’ll be well above 3,000fps MV from a 16” 22CM.

There is no upper limit. I shoot in the neck to keep the cleaning table tidy. The 77 TMK has show ability for me out to 500 on a rare occasion.

There is sone staggering photo evidence of elk kills over 400 yards in this thread if you read all of it. Key to this success is not using traditional bullets.
