Working up load

Do you think a gun will be accurate with any and every abstract charge?

I wasn't expecting groups to open up that much, but that's almost +200 fps increase. So I will step down and I might just get it right...

You may wanna try a load with benchmark starting at about 23grns or a load with H4895 at about 24.5grns.

Well how fast do you want to miss?? Have yet to find a round that prefers Varget...Probably because it isnt as accurate @ full throttle. Tac/H335 however are about as good as it gets for full throttle loads with the 55s in the 223 with Benchmark showing promise in some rifles.
My J action Savage only likes the 55SPSX in front of a medium load of AA2200 so guess what I load for it Yep you guessed it 23.5 grains of AA2200 a CCI 450 primer and the 55SPSX set @ 2.31. It aint fast,preaty or famous but it sure is a prairie dog killer inside of 250 yards!!

Try between 25.5 - 26.0 of IMR 8208xbr. I have found it to work wonders on the 50-60gr's.

I did few loads with H335, was not bad, but Varget is making tighter groups, also I had some good results with IMR4064 and RL15. So what Benchmark and H4895 can yield? I guess I can try them out, thing is with 1:12 twist I have limited selection and for some reason it doesn't like BT bullets. Although 55 gr Nosler Ballistic Tips were the only BT grouping well.

IMR 8208xbr that's something new, never heard of it, looks like it can me loaded in 308 and 260 I hope. Universal powder that's what I'm after
I tried Trail Boss, its subsonic alright, but grouped terribly like 3"@100.

I have found it delivers both speed and accuracy in my .223AI, .223 & 22-250 loads.
Just wish someone around here sold it in a keg at a decent price. Sportsmans has it for 21.99 lb.
