6.8 based wildcat- 16" barrel
If you are looking for the most reliable and best all out terminal performance on hogs and deer out to 300yds the TAC 30 is it. The rounds hit like Thor's hammer...DRT, a perfect match for Texas hog hunters. I've heard some 300 Ham-r and X40 cheerleaders say it is as fast as the TAC 30. It has 5gr less capacity, it isn't as fast. The TAC 30 is 150-200fps faster than the ham-r or any 5.56 based 30 cal. The 6.8 cases will handle 58000psi easy.
The Cavity Back bullets 125gr MKZ open to .800" diameter, imagine the wound channel! They are pushing the 125gr MKZ to 2775 out of an 18" barrel with 29.4gr of SW blackout. That is 150fps faster than a 20" Grendel and 450fps faster than a 300 Blackout. The Herrett using SW BO powder is as fast out of an 18" barrel as the 30 Remington AR was out of a 24" barrel. The TAC 30 is big brother to the TAC 6 cartridge. It is a wildcat that you must reload, form and trim cases but you do not need to fire-form and you don't need to modify mags like the BO or Ham-R.
4150 CMV 30 Herrett mid wt profile, Hybrid 5R rifling 11.25 twist . 2lb-2oz
M4 feed ramps, mid length gas system, .850 taper to.750 under the guard, .750 gas block dia. .700 dia from gas block to muzzle. 5/8-24 thread muzzle.
30 Herrett reloading dies are used with a 6.8 shell holder. 6.8 SPC brass is easiest to use, S&B, Hornady, Starline in that order. Trim to 1.570, 1.580" is max case length. It is important to size the brass close to the chamber size. Set the dies up where they push the shoulder back just enough to chamber the brass. Hornady 30 Herrett dies seem to work best but again be careful not to push the shoulder back too far. The 30 Herrett was a wildcat many years ago and the older dies vary in size. You do not need to fireform or turn the necks on the brass. Just trim, size, load and shoot.
The 30 Herrett in an AR can be loaded to higher pressures than the old TC pistols. With 125-130gr bullets Shooters World BO, 1680, 4198 and RE7 work well. S&B, Hornady, Starline, Federal brass in that order works best. I would not use Remington large primer brass. SSA brass made by Nosler was soft, may change or may be better now still better than Remington.
Suggested maximum loads-16"barrel
125gr Sierra prohunter loaded to 2.240-30.5gr 1680=2610fps CCI 450 primer
125gr Nosler Ballistic tip loaded to 2.3"-30.5gr 1680=2680fps CCI 450primer
130gr MK319 30gr AA1680 =2590fps -very accurate and a great hunting bullet
110gr Barnes TSX loaded to 2.295, 31gr 1680=2678fps
110gr Barnes TSX loaded to 2.295, 32gr 1680=2796fps
All loads produced groups in the 3/4-1" range and should be good for hunting, 100-200fps faster than the 6.8.
The Hornady 125SST was not as accurate as the bullets above.
28.5gr 1680 behind a 125 TNT hit 2500fps out of a 16" barrel.
29.5gr 1680 apx 2570fps with 125gr Speer TNT or Hornady SST loaded to 2.3" is a good load.
30.5gr 1680 =2655- 57000psi-Should be considered max load , do not load hotter than this.
150gr Nosler BT-27.5gr 1680=2366fps
