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

In my .223's
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.
