Im keen to warm up my 6BR a little for varmint shooting at night under a spotlight. Have been loading 33.8gr 8208 behind 55gr noslers with no pressure signs around 3650fps. Accuracy is good enough, but not brilliant for a 6BR. Chamber is a .272 neck with 0 freebore. I have access to RL10x and H322 but nothing else like 2230 or N135. Any suggestions on a powder of choice?

Powder of choice is AA2230 with Rem 7 1/2 or CCI BR-4, velocity is 3900+ out of a 26" barrel, and 3/4" at 300 yards
H335 would be a second choice, tiny, tiny groups, 60g Sierra and 58g V max are excellent also,but B.C. of the 55g Nosler is fantastic.
Accuracy spread is huge with these powders, and the hotter it gets, the better they group.
Gene Harwood, NBRSA director, sat a world record with the 6 BR with his own 60g Bullets using H335 at 3700 fps out of a 24" with crappy Rem 6 BR brass....what's that tell you?
8208, H322 are slow compared to aa2230, and all are very accurate. Barrel life with H335 and aa2230 are nothing short of unbelievable.

Thanks- I knew 2230 was the best from any web searching but in Aus we dont have it available. Any of the extreme series powders from Hodgdons we can get here as they are made here. Can also get alliant powders too hence why I thought RL10x might be worth looking at. It had great velocity in 20 cals based on 223 cases.
