Need load for Barnes .223 Varmit Grenade bullet.

[ADKWOODSMAN]

Barnes Bullets lists a load, on their web site, for their varmint grenade .223 36 gr. bullet with a load of benchmark of 25 grains and TAC powder of 27. 5 grains as starter loads.

There is none of this powders locally and I have the bullets so I’m wondering if anyone has loaded these bullets With IMR 3031 or IMR 4895 as these are the powders I have?

TAC has a burn rate listed as No. 109 on the burn chart on www.reloaderbench.com/burn.html and IMR 4895 has a burn chart No. of 114.

Benchmark is No. 95 and IMR 3031 is No. 94. Would a starting load of IMR 3031 in place of Benchmark and a load of IMR 4895 in place of TAC be O.K. or should I start 10 percent below these starting loads?

Im shooting 35 gr Hornady vmaxs in my 223, with 28 grains of varget (vibrated, and compressed) Start with the base load and you should be good-

I wanted to give those a try but from what I read you need a slower twist then a 1 in 9.

I'll be trying some today in a 1 in 9 using benchmark, I'll let you know.

Idano, they shot pretty good in my Bushmaster a little over an inch in a gusting cross wind on a crappy bench.

In my loading experience, I found that lighter (36 gr varmint grenade especially) bullets need a slower, 1:12 or 1:14 twist in .223. A lighter bullet gets unstable at faster rotation. Both my .223 AR's (Bushmaster XM-15 & Rock River A2 Varminter) are 1:9 twist and they like 55's, 69's & 75 gr bullets. Most of my shots are at 50 & 100 yds from a rest.
YMMV

I think the varmint grenade is a no lead bullet,therefore long for a light bullet.I got the idea to try it in my xm from a poster on here that said they key-holed in his hornet.

Doug b, did you shoot 36gr or 50 gr varmint grenades?
What twist?
