Getting 2640fps with 75 amax's outta the same rifle. They are loaded a bit further out thoughNot sure how much extra the AI will buy you, but I have a Ruger American Ranch at 16.5" and it gets a bit under 2600fps with the UM factory 77tmk (@ AR mag length, loaded with XBR 8208) ...I think you'll break 2600.
You might be in kissing the lands with those, just check when you get them. In my factory chamber those would be .020 into the lands. Assuming your talking a tikka.
It is a tikka. My newbness is shining through today! Solid points on the wind calls past 350/400. I still have a lot to learn in that department and don’t plan on slinging rounds at game just because the gun can do it. I’ve walked away from 500 yard shots before so I’m sure I can do it again if need be.You might be in kissing the lands with those, just check when you get them.

Is that small hole at top left an exit? Looks like the bullet impacted at quite a steep angle.
Ah, I see that now. At first I had thought the exit wound was the small perforation? spot of coagulated blood? a couple ribs below the actual exit as it looked roughly the size of an expanded 77 gr TMK bullet.Arrow is pointing to entrance, line is the path, and square is exit.

Out of stockFor anyone looking for factory loads, I just grabbed 200 of these:
Stand 1 Armory RCP 223 77gr Sierra Tipped Match King (TMK) - Stand 1 Armory
Stand 1 Armory 223 77gr Sierra TMK 77g Sierra Tipped Match King (long-range precision): These polymer tipped 77g Sierra TMK bullets buck the wind very well and produce extremely consistent results at distances out to one mile. These are the best long-range 223 bullets on the market, and are...stand1armory.com
Ran great in my LMT:

Stand 1 told me "these are loaded pretty hot and we are getting 2700 fps in a 14.5" gas gun." Looking forward to giving them a go on game.
Hey thanks for the reply!
I can tell you from my standpoint, I was squarely where you are. I’ve been on rokslide awhile now and have developed some friends, western based guys. When I look at the level of man years of the identifiable advocates on this thread we’re talking a very lot of man-years of western hunting experience. Also have other friends here who took this plunge, and aren’t planning to use their magnums any time soon - me included. At least at the range limits noted here.
With utmost respect to your years of western hunting experience it’s much less than the combined years of the original advocates and many many others who embarked on this information and have made kills.
If you personally haven’t used a tmk in this caliber or witnessed a kill personally how can you summarily dismiss based on your years of western hunting minus this data point?
Wherever they end up below 1800-2000 fpsEven with a week off, I don't think I have enough time to get a 115 pages of info read. So I'll just ask. What has been the decided range for the heavier bullets on most of the game animals that have been discussed? Thanks.
The post is “.223 for bear, deer, elk and moose”. As I stated earlier, if it’s legal in your state go for it. Even with the 77 gr TMK, it will fall below 1000 ft/lbs of energy around 160 yards. For small deer at close range (less than 200 yds) its probably fine. For large deer I feel it’s marginal, especially at range. For bear, elk or moose its probably unethical. Magnum cartridges are unnecessary however I feel we owe the animal a quick clean dispatch with a cartridge best matched for the quarry. I realize this is an unpopular position on this thread, however I respectfully disagree. After 30 years of military experience with 5.56 cartridge, I have doubts on its suitability for big game.Hey thanks for the reply!
