Anyone getting good accuracy out of TAC in 223? - AR15. COM TAC is my base powder in 223, and it’s the first powder I try when testing a new bullet It can give fantastic velocity all of the time and great accuracy some of the time In 223, there is typically a 2 gr window in the 5 56 pressure range when SD’s will be single digits
Best powders for particular grain ranges of bullets in 223 556 - Your . . . TAC throws with SD = 0 014 gr, however, this low dispersion of charge weight does not show up as low dispersion in muzzle velocity (VBarget has lower MV SD than TAC) The accuracy and SD numbers given above are for large sample tests (# of samples, n>20, typically about 100 samples)
Reloading 6. 5 grendel, any tips or suggestions on powder? - AR15. COM 26 7gr of TAC topped off with a 120gr Gold Dot got me a 96" 5 shot group 26 6gr of TAC with a 120gr Sierra Pro-Hunter was just a shade over 1" with a 5 shot group I don't know what kind of velocities I'm getting since I don't yet have a chrono
H335 - Whats its equal? gt; Reloading - AR15. COM It's anecdotal, but for what its worth when comparing wc844 to tac both loaded to 5 56 pressures in a 11 5 barrel, WC844 will make some nice fireballs where with tac it is almost non-existant Given where tac and h335 fall on the burn rate chart I would have thought it would have been the opposite
68gr Hornady BTHP 5. 56 load data gt; Reloading gt; AR15. COM AA 2460, Tac, 2230, all 3 will get want you want AA's website has all the info you want for 62,00psi loads, Ramshot Tac and 2460 looks like the best, and maybe 2230 for a shorter barrel For 223 pressured rounds 2230 is hard to beat, 2015 for lighter bullets is perfect But for NATO rounds
Recommended Powder for Sierra Matchking . 22 77gr HPBT - AR15. COM These TAC groups are normally in the 0 5-0 75 MOA range but all above powders have produced MOA or better groups Over-mag-length 80gr Berger VLDs worked up over high pressure TAC loads are showing a lot of promise for use at long range but have not been tested past 500yds yet My last 5 56mm barrel preferred Aardvark's 77gr
