I have been useing Varget for 55gr. and H-335 for 40gr. all my Bolt Guns and getting 1/2" groups. However with my new AR 1:8 twist I would like to experiment alittle.
Considering these Powders: TAC Exterminator Benchmark Anyone have any Pet Loads with any of these. Also would like to try some 60gr. Pills |
| Try Ramshot's Xterminator powder with 55 gr bullets. I get more velocity out of 16' and 20" barrels with it than with Tac. I also use it with 50 gr Hornady SPSX in my 26" bolt and it gives the best accuracy of any powder I have tried. As a point of reference I have used 748, BL-C2, H335, Varget, RL-15, and 2230 (far and away the dirtiest powder I have ever used in a 223) in ARs and my bolt. Unless I go heavier than 55, I will only use Xterminator. |

I use TAC and 2230, with the light bullets your shooting I would stay away from TAC and go with 2230 Same here. 2230 for 55's 62 and up get Tac Same here. 2230 for bulk reloading 55gr, and TAC for all else. I find both are near identical in accuracy, for me at least. I also use the TAC for .308 150 gr Hornady FMJ's. |

For now I'm using H335, TAC and WC844.
But I need to order some of this to try out in some 75 grn Hornady T1 and 77 grn SMK loads. http://www.sinclairintl.com/.aspx/sid=72737/pid=34652/sku/IMR_8208_XBR_Powder___8_lb_?utm_medium=shoppingengine&utm_source=googlebase&mc_id=8000 |

I use Tac, H335, H322 and Varget. Varget great for heavy bullets but pain to meter, H335 good on 55 like mentioned.The H322 is great on Sierra 52gr SMK (1:8) and the TAC is awesome in anything really.
I think TAC smells good when it burns too...but i might be brain damaged by now. 
Hornady 55gr FMJ TAC 25.6(it was worked up to that) Sierra 52gr BTHP Match H322 23.4 (worked up from 22.8) Same Sierra 52 but with 26gr TAC( seems like i started at about 24.5) Nosler Ballistic Tip Spizer 55gr TAC 25.6..(worked up). My favorites |

Main two loads I tried were with Hornady 55SP on top of TAC and H-335
I think it is liking the H-335 Still need to do some more testing, but things are looking better. I shot alot more groups and with other loads, but these were the best perfomers. I did notice that it shoots better when clean, after about 12-20 rounds things start to open up, I wonder if hand lapping the barrel would help. First group was 24.5 and the second was 24.8 
And the TAC load: First group was great, that is 4 shots, but the second group opened up. I also tried 25.0 of TAC but that wa sno good. I will test more with 25.5 and bump it up alittle. I like that TAC, burns really clean, H-335 is not bad but TAC is alittle cleaner burning. I did notice that the TAC recoils much softer as well
