I am about 70 rounds into this load development with not much to show for it. I did a powder test and found a decent area with Low ES and SD but best groups were 1.5 MOA. I’m now doing a ladder test with seating depth. I bought a metal ASC to gain a bit more COAL up to 2.315. I’m going to now increase OAL in .006” increments from 2.260 out to 2.315 and hopefully something works. I’ve never had a load give me so much trouble. 223 wylde 20” 1/8 twist 77 tmk and ram shot Tac. I’m not giving up yet because dang I really want these to work! Just need a sub moa group consistently and I’ll be happy.

Velocity by the way has been 2840 fps. Screaming

I wasn’t getting anywhere or finding any good loads at all with the 77tmk with a couple powders but 23.3 of tac has been like magic in my rifle

Going to try out some 75 ELDMs on deer this week. They’re going 2925 out of my CTR. A friends pepper crop is getting wiped out.

In my other rifle which is a 223 predator im running tac with a 73 eldm and it’s shooting 0.3 ish moa on a good day. Not sure why these 77s are giving me so much trouble! I may have to settle for a 1.5 moa group lol

Thanks I grabbed a couple of pounds. It has been a pretty rare powder. I don’t know if it is better than TAC but I will run a future comparison for my rifles.

Long enough for guys I load for to get some so they don’t have to scavenge off me. Now we need some 77tmk in stock
They’re out there, I snagged 300 more last weekend while in Utah. Surprisingly the store didn’t have a limit and had 6 boxes on the shelf.

What rifle? What twist on the barrel, and what barrel length?

A 20” 223 wylde chamber with a 1/8 twist. AR15. I guess my next step is to increase seating depth out to 2.310 with new metal ASC mags and see if anything improves

Ive never been abke to get the TMKs to shoot as well as the SMKs out of my ARs. 77 SMK over 23.4 of 8208 or 24.5 of TAC is money in most ARs ive shot and competed against.

I was not able to either. I put a new BA 16 inch fluted barrel in 223wylde on it and voila. 24.1g 8208 and 77 TMK at standard length. Regularly can get right at .75 in my gas gun. Now I will work on decreasing the length a bit. 1/8 twist

I pretty much gave my brother in law my AR, but with 77gr smk’s, it was the most accurate rifle I have owned… it was fairly picky, but those smk’s shot crazy well… I plan to load him up some tmk’s soon, and I hope they shoot well, but I have heard the same thing you mentioned out of gas guns
