.223 powders

Re: .223 powders

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: longrange30</div><div class="ubbcode-body">Also what are some good powders for .223 from Alliant or IMR or any other brands.

52-53gr.
62gr.
68-69gr.
77gr.</div></div>

As nativecraft mentioned RL-15 and Varget are the most used. I used Varget for years in Highpower comp. Then Benchmark came out and I used that to get Gold and make the Presidents-100 at Camp Perry.Also Benchmark meters better.
 
Re: .223 powders

62 grain bullets and under, I have the best luck with Benchmark and Win 748.

With bullets over 62 grains, Varget has given me the best results.
 
Re: .223 powders

TAC is a good powder for USGI ball-equivalent loads, being in ths same burn rate range (roughly) as W748. Big Game is more like W760/H414, and Hunter is more like H4350.

For .223; I'd use TAC for 40-60gr, and Big Game for 62-77gr. Never went with any higher bullet weights than that, but for the heavies, I'd try the Big Game, and if it was too fast, try the Hunter.

Re: .223 powders

I use nothing but RL-15 in my service gun, 24.3 grains with 77 SMK's and 25.0 with 80 grain SMK's, they both come out at around 2750 FPS. Have never had a failure at the local ranges nor Perry. Headed out there next week.
 
Re: .223 powders

I have used TAC with VERY good results. This is the powder that Black Hills uses for the Red Box 50gr Vmax load. I just duplicate their load....24.8gns of TAC OAL 2.250. Shoots sub 1/2" five shot groups at 100yrds out of my Tikka T3 Lite....and has bagged many a yote as seen in these videos from a couple of my last winters hunts

Take care,Stan

Re: .223 powders

I've gotten the best out of my Sig 556 (1:7 barrel) with 77gr. SMK's over 24 gr. of TAC. That's about 2550 fps. out of a 16" tube. I've also gotten nice performance out of the same bullets with slower powders like 4895 and 4064 but they don't meter nearly as well.

62 gr. bullets over 20 gr. of 4198 is also a very accurate load in this rifle, but it doesn't cycle consistently at the normal gas valve setting without a can on.

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: NativeCraft</div><div class="ubbcode-body">Alliant's Reloader-15 is the .223 powder. Either that or Hodgdon's Varget. </div></div>

These are the two that work best for me.
 
Re: .223 powders

I'm getting good results with 748 with 55 and 62gr bullets. I load 223 on a 650 so I need a ball powder, how ever I load 308 on a single stage press and 748 has given the best results there too.
 
Re: .223 powders

I just today attempted to duplicate the Black Hills 77gr SMK load. Rifle is a Tikka T3 Varmint with 24" 1:8 twist barrel. Ambient temperature 94 deg.

BHA 77gr SMK match ammo
avg. velocity = 2774 fps
st. deviation = 15.8 fps

77gr SMK, 23.6 gr TAC, Rem 7-1/2 primers, new Winchester brass, OAL = 2.26"
avg. velocity = 2778 fps
st. deviation = 15.9 fps

New cases had primer pocket deburred and neck sized and chamfered, but were not trimmed.

An article in the latest issue of American Rifleman presents some results for temperature dependence of powders. His 223 load using TAC showed zero change in muzzle velocity between 0 deg F and 70 deg F. Seems to be good stuff and more available than some other powders.
 
Re: .223 powders

I've had good success with TAC as well with the 77 gr. Sierra HPBT in my 18" MSTN AR.

Given my barrel length, I'm loading hotter than the bolt guns with 24" barrels.
24.3-24.4 gr. TAC (Win brass, WSR)
Yields 2730 fps average with 14.8 SD (at 6000+ ft. altitude, 80 degrees).

Accuracy is pretty good as I shot 3 .5-.6 MOA 10-shot groups at 425yds.
And my experience is like Guinness's -- I can usually get it w/in a week.

I defer to others on various other powder results. I was just trying to get a serviceable 3-gun load with available components and TAC was recommended -- it's worked well for me in this application.
 
Re: .223 powders

I keep trying to make Varget work with 69g SMKs in a match barrel (1 in 8) because I have almost an entire 8lb can of it, but IMR4320 wins every time.
 
Re: .223 powders

Hunter is the ideal Ramshot powder for the .260 Rem and the 140's. Think of it as H4350 in ball form. Since most serious .260's wear custom barrels; I'd be hesitant to specify loads. But as a ballpark, I'd consider the 140 SMK and A-Max, also the 140 SST for hunting, the 142SMK and 139 Scenar, and start my loads at 42.0gr. First things first, do incremental pressure testing for <span style="font-style: italic">your</span> barrel. The 120 Nosler BT and 120SMK are very good for semi's and upclose, and the 95 V-Max is a flat, accurate, and devastating varmint bullet. For the 120's and down, the Hunter will work fine, but Big game is also worth trying, maybe even TAC for the 95. My 95 V-Max load is 47gr of H4350, a Hodgdon published <span style="font-style: italic">minimum</span> load. I use the minimum because I'm being cautious about running bullets at 3400-3500fps through a 1:8" twist.

Re: .223 powders

BgBmBoo you sent my Wifes dogs into a tizzy. The sound on my computer is down so low I can barely hear it in my lap but those dogs heard it in another room of the house. They knew exactly what that was they have heard it many many times before.

For my 223 I shoot a 55gr ball and I was working up loads with Varget and I did not like my groups so I switched to Benchmark and my groups have settled way down.
 
Re: .223 powders

Im not sure why but NOBODY seems to use H322 except for me and one of my buddies. Its more fun in a bolt gun where you can load them hotter but hes running all of his service rifle loads with H322. It has been incredibly accurate with everything from 45grn V-maxes up the the 77grn Matchkings
