I am working through a bunch of powders to find the most accurate overall load for my .223 AR and my .308 bolt gun. Once I find the most accurate for my good precision rifles, I'll make that my main load and load most of my plinkers to that load too.

I have a batch of new Winchester .223 brass for the .223 and Lapua brass for the .308


I have tried TAC for the .223 and got about 1.5" off a wobbly shooting bench in the wind. It shows promise. I need to get on a concrete bench where I can see how accurate it is really.

I have not tried anything in teh .308 yet.


What are your pet accuracy loads I can try?

Currently shooting 22.8 gr N133/69 gr SHPBT in my AR with 1/8 twist. 23 gr X-terminator/69 gr SHPBT in LTR .223. 43 gr RE-15/165 gr SGK in .308 LTR. All three rifles shoot these loads excellent.

For out to about 300-400 yards, my favorite .308 load in my 1:12" 26" Remington VLS is 45.0 gr Varget, Hornady fire-formed match brass, collet neck sized, CCI LRP, with a Hornady 150gr SST (yes, a hunting bullet!). About 2800 fps.

.223 in my 1:8" ss AR is 24.5gr Varget in once fired LC brass, Sierra 69gr SMK. About 2750 fps.

Varget is a favorite if you can find some. It measures poorly, you will need a drop tube. Accuracy is great in both calibers.

I like Re -15, same accuracy, a lot easier to load.

Tac is a great powder, just not quite as accurate as the 2 above.

I've got half pound of Varget left. I have never used a drop tube. will Varget meter out of an RCBS powder measure?

24gr. IMR 3031, 52 gr. Hornady HPBT, CCI SR, LC once fired brass for .223
21.5 gr. Reloader 7, 52 gr. Hornady HPBT, CCI SR, LC once fired brass for .223
* If using once fired make SURE they are trimmed to proper length, this CAN effect accuracy as much as 3/4-1", in my gun anyways
RRA with 24" in 1-10" Bull Barrel

Honday 68gr OTM
23.3gr AA2230
ATI '09 cases


Got amazing groups with this at 100 yards considering armalite advertises my rifle as 2-2.5MOA. Also i wan only shooting 3 shot groups to compare different loads of powder. between 32.1, 23.3, 23.5, 23.7. The 23.3 did the best, none other had hole touching, im guessing it was me though, not the ammo.

Yuppers.

When I worked up my loads, there was no varget anywhere at least up here, VVN 150 is a great powder, it's meters well, burns cleanly, the only downside is it's a little more expensive than varget.

For .223, 69 SMK, 25.3 Varget, LC brass and Rem 7.5 primer. 10 rnds @ 100 into .5x". This is Sierra's accuracy load for this bullet. About 2800 fps out of a 20" 1-7 Krieger.

just picked up some Varget, and some H335. Will try and find some Vihtavuori. I like Vihtavuori cause I speak Finnish, but that stuff is expensive

.223: 25.3gr Varget, Nosler 69gr Custom Competition, CCI400

.308: 45.7gr Varget, Nosler 168gr Custom Competition, CCI200

I didn't see any difference between Sierra MKs and the Nosler CCs but the Noslers are cheaper.
