Ramshot Tac for AR 75/77 gr loads???

HiBC · March 2, 2010, 02:30 AM

I just built a 20 inch .223 AR,1 in 8 twist.
I am working on loads with 77 gr MK's,77 gr Berger match,not VLD,and 75 gr Hornady match.First time out I tried some RE-15 and Varget.Velocities ,so far,are as the Sierra book predicts,in the 26 hundred plus range
One powder I have never used shows better velocity, Ramshot Tac,and is in Sierra's AR 20 in data.
Has anyone tried Ramshot Tac ?? I have not,yet.I am curious as to how clean it burns,as in does it crud a bolt carrier? Is the gas curve such that it is friendly to an AR?

I'll try it out,I guess,but feedback is welcome

Yes TAC is about my favorite 223 powder, especially 55 grns & up in the AR. I did an informal cleanliness test with H-335 & TAC won out handily. I know H-335 has a strong following & has been a top AR/223 powder but I have not bought any in years. It's also usually available, at least mail order. I buy 8 lb jugs now.

TAC works well, and it's all I use these days for 223. I had been using Varget, but it got too expensive and it doesn't seem to hold any advantages over TAC.

RL-15 works much better for 69/77 SMK .223 Rem handloads. TAC is good for 64 gr and under.

Thanks,folks.
I put a Pride-Fowler 10X scope on it with a Rapid 800 ladder type reticle.
I'd like 2700 fps minimum with a .360+ BC @ sea level.I'm at 5000 feet,with the altitude correction and the AR scope height the trajectory should work out quite well.
My Sierra load manual gives a velocity advantage to TAC,at 2750 from a 20 in AR.
Per the manual,Varget ,Re-15 and the rest are about 100 fps slower.

As TAC is a double base spherical powder,I also wonder if it may be more erosive.
Its a premium bbl and it cost some.

I like TAC just fine for my handloads from 55gr to 75gr bullets. Haven't tried any heavier bullets. I used to load BLC-2, H335, H322 & Varget.

TAC also works well in my .308 & 30-06 loads. I recently tried H380 in 30-06 with very good results, but the final verdict is not in yet.
