Hey,

I was curious if anybody has tried to work up a sub-moa load with 75 or heavier grain bullets?? I would like to try to work up a 1000yd. load with it since it acheives higher velocities, but wanted to see if anyone has gone before me first...

Thanks,
Tres

I have had great success with Tac. Shooting it with 68, 69 & 75 grainers. I have found Varget to be faster with the 75's though. Excellent powder choose.

TAC powder works "very well" with the heavier bullets in 223 Rem. 5.56mm LR aka MK 262 (Mod 0 and Mod 1) is manufactured by Black Hills. From memory, MK 262 Mod 1 has a muzzle velocity of approx 2820fps from a 20 inch barrel. SF has used this ammunition with great success. Not sure if the data is still available but, it was/is loaded with a little know powder, C1700. C1700 is a canister grade powder from Western powder company. Probably better known is its commercial equivalent "Ramshot TAC." And now you know the rest of the story!

23.0 grains is a good starting point with the 77's. Work up from there watching velocity and pressure.

Thanks fellas.

Are you guys saying Varegt gives higher MV with 75 & 77 bullets over Tac IN A 20" BARREL?

Thanks again!

Winchester Western C1700 loaded with the 77gr. SBTHP shooting out of a barrel of 1/5 twist is the most accurate you can get with the .223 round.

I have good luck with a 1-7" twist with 77's-90's and Varget.

Where do you get a 1-5" twist?

I, too am using TAC. Out of my 24" 7twist hart long range AR-15, 23.6 grains of TAC, virgin winchester brass, CCI BR-4s, sierra 77 grainers seated to 2.260. avg velocity is 2846 fps through chrony. very accurate. 24.0 grains of TAC is listed as max load in sierra manual for ar-15 with 77 grainers. Work up to that load. CCI primers can handle the pressures better than the winchester small rifle primers i tried.
