Careful what you say, he is an instructor
Did you stay within the legal threshold of powder when you loaded those rounds? I heard game wardens in some states hide in the shadows with a chrono, checking muzzle velocity, just waiting to give you a speeding ticket for shooting too fast of ammunition, it falls under the “meat recovery act” and it can be a fine of 5k and 42 seconds in prison for first time offenders, and 3 offenses can lead to a suspension of your tmk reloading licenseAnyhow, loaded some more 75 Amax and 77 TMK with a different powder that I have enough of to last a while. Chronograph is along this time. Don’t think I’ll see XBR this year on the shelf in my area. I’m at the farm by myself for 2 days and then my wife and daughter will be up so I may as well make hay while the sun shines.
Here is another load test: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
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.
I sure would like to know your friends load. I have the 22 CM and the 64gr TGK. Seems like a good combo.A friend shoots the 64gr TGK out of his 22 Creed for coyotes. Not fur friendly, but they don’t go anywhere.
Around 42.6 of H4350 depending on the lot. Necked down Hornady brass.I sure would like to know your friends load. I have the 22 CM and the 64gr TGK. Seems like a good combo.

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.
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.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 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.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.
