Try the 75 amax/eld. You may be surprised to find you get stability from that Ackley cartridge.
60 gr TMK?
- Thread starter grovey
- Start date
Doubtful without saying NO WAY !!! Hard to say never in this game.
I always thought Sierra had the best bullet viewing website ever. They just changed it.... Its terrible.
I am not sure what the point of a 60gr TMK is? Why would somebody buy those over the 69gr version? Especially for shooting at distance and/or in the wind.

284Winner is pretty spot on and I'd say unless you were shooting these things from the top of Mt Everest, they probably aren't going to shoot very well for you in a 14tw anything.
Unfortunately, that 14tw barrel is going to limit you to shooting bullets around 52gr and lighter. That's the bad new, but the good news is you should be able to make the 52gr Amax or 52gr ELD-M shoot very well in that particular gun. A few years ago a good friend of mine had a Winchester M70 22-250, his was the Coyote model. I worked up a load for his with Hornady 52gr A-max and H414. It shot that combination extremely well and if I recall, with that particular load, they were leaving the barrel around 3700-3750 which is no slouch from a 24in barrel. Doubt you'll find any 52gr Amax, unless it's some old stock someone has sitting on the shelf, but the new 52gr ELD-M is pretty much the same bullet so they should work as well, if not better.
Just depends on what twist a person's barrel is. A 10 twist may not stabilize the 69s in some guns. Some guns may shoot the 60s with a 12 twist. The 69s may not in either.
Probably a combination of being able to push them a little faster with a G1 loss of only 0.052. Also, the 60s are running about $0.18 per while the 69s are $0.28 per. More than a 1/3 cost savings isn't something to sneeze about when you're buying 1000s of them. I'm really thinking these might be interesting on a prairie dog shoot or for coyote hunting. I have 350 I need to load up and try soon.
I am able to push these out of a 24" AR with a 8t barrel over 3200fps with good results. For someone looking for a bullet that sits between the velocity of a 50gr and the ballistic performance of a 69gr, this bullet is the cats meow. Price is a plus and that green tip sure makes me feel special.
Can you share more info on this? That sounds high out of a bolt gun, let alone an AR! Varget gets some of the better numbers with this bullet from the info I've seen, and that's at about 3160 with a compressed load stuffed like a Thanksgiving turkey. Be safe fellow shooter.
Older post but figured I’d update with some info. I loaded up some of the 60 TMK in 1/2gr increments of R17 in a 26” 22 Creedmoor starting at 39 gr. SRP Peterson brass was used that I had to drill flash hole to .080” to prevent hangfires. Velocities went from 3300 up to 3780fps and I loaded 7 of the 3705fps load. They shot into 1/3 MOA and I think I have my coyote hammer right there. Barrel is a 1-8tw but I wanted to hold on fur as far as possible and this should do it!
3700+ and a bullet with a 0.323 G1? That is great!
Yes, the 3705fps load went up to 3730 with the enlarged flash holes and shot very well. Looking at the #'s for trajectory, it's as flat to 500 as any of the higher BC VLD's at 3500 and under, but the heavies (75-80gr) do have a noticeable advantage in wind from 400 on out. Since I'm looking for a rifle to shoot coyotes of opportunity spotted from the house, distance is usually 300-600 yards. I'm going to shoot some 75gr Amax and see how they perform. For a calling rifle and typical 50-300 yard shots I think these will really work well.
73 & 75 eldm's are mean on critters, especially when they start their journey around 3500fps+
I asked a gent at Sierra the same question before these became a full time offering. They were originally developed as an option for departments/agencies/armed forces groups that are required to shoot match bullets instead of hp or sp options due to certain restrictions, but who still wanted improved terminal performance over standard ball ammunition options. Based on what I have seen with these out of my 223ai in the 69gn flavor...it makes perfect sense. It is still technically a match bullet, so it fits in the proper category, but it comes unhitched relatively quickly once it hits soft tissue. Best of both worlds for those guys.
Is anyone running the 60 TMK out of a 223 AI? What are your experiences with them?
scroll down in Sierra's add/listing and it shows BC.
So far I have shot the 60 TMK in 3 rifles with sub half moa accuracy in all three.
1. 223 7 twist. 2. 223 AI 8 twist (fireforming only as I my size die was messed up from the factory and they haven't replaced it yet.) 3. 22/250 10 twist.
So far I have shot 12 coyotes and recovered 11 using the 22/250 at 3650 FPS. No velocity data yet from the 223. A guy on predator masters reports 3500 with a 223 AI AR15 which I have to think is rather hot.
A brief description of the coyote kills are as follows.
Coyote 1: 311 yards. Broadside. POI crease of the shoulder. Bang Flop, no twitch that I saw but I wasn't looking really. If I know a yote is down I am watching for more coyotes not ogling the one on the ground. Exit wound was about 2 inches.
Coyote 2: Approx 100 yards, Broadside, POI crease of shoulder, bang flop with no observed twitch, small dime sized exit.
Coyote 3: 549 yards. Broadside, POI right on or just behind the diaphragm (too far back). Coyote ran 100 yards and laid down in a small wash. Dime sized exit. Walked over and gave a finisher at 40 yards to the back of the head with the predictable graphic results.
Coyote 4: Approx 100 yards, straight on, bang flop with no observed twitch. No exit.
Coyote 5: Approx 50 yards, coyote turned right as I shot and bullet raked its side. Yote did the death spin for 20 yards and had a 3 inch tear. Can't blame the bullet on this one obviously.
Coyote 6: 318 yards, broadside, POI pretty much dead center of rib cage, Coyote did a death run for maybe 40 or 50 yards, 2 inch exit.
Coyote 7: 564 yards. I screwed up, remembering yote #3, I gave a touch more windage. Looked like the impact was low and forward on the shoulder. Yote was laying down so it was hard to tell. Looked until dark but was unable to recover.
Second day:
All yardages are guesstimates as I forgot my rangefinder.
Yote 1. 200 yards. Broadside, POI top of shoulder. Bang Flop. 2 inch tear. Mangy dog so oh well.
Yote 2. 100 yards. Broadside, crease of shoulder, Bang Flop, 2 inch exit.
Yote 3. 200 yards. Broadside, POI top of shoulder, Bang Flop, 3 inch blow out.
Yote 4. 50 yards. Straight one, Bang Flop, nickle sized entrance, no exit.
Yote 5. 50 yards (was 10 yards from #4 when #4 got hosed). Broadside. POI rear shoulder. 20 yards of circle spin. 3 inch entrance, no exit. Saw the splash in the scope, knew right away it was a splash.
Up until the last coyote, I contemplated using them on a meat doe but the close range splash moved me to load up (my go to) 68 grain hornady match which a friend used to great effect on a big mulie doe at 204 yards. 4 inch hole through the lungs with chunks of lungs on ground from the exit.
Going to keep using the TMKs the rest of the year on yotes however I expect the trend not being overly fur friendly to continue.

I'm thinking about building a short barreled light-ish 22 Creedmoor to shoot the mid weight bullets. My current idea/plan is to use a 10tw, seriously considering one of Frank G's Bartlein barrels in maybe a 5R rifling, and though I've had great success with the Hornady 53gr Vmax the 60gr TMK will likely be my bullet of choice for this particular build so it's good to hear they're not only shooting well but it sounds like they do a number on coyotes too.
