best powder for 16 " AR,75grain

[steve123]

I'm trying to decide what powders to use in my 16" AR with 75 grain Hornady HPBT match bullets.Do you guys know what the best powder is for a short barrel and heavy bullets?On hand I have Varget,AA2520,AA2200,Benchmark, and H4895.All the data I've seen are for 24" inch barrels.
Thanks,
Steve

I found out this morning that with H-4895 there was an increase of approx 150 FPS for 24.6gr at 2823 FPS.The other three powders were around 2650 -2700 for the benchmark,AA2520,Varget.

2230 has always worked for me

I've had good results with AA2230, H4895, R15, TAC and Xterminator. BLC-2 gave me poor results in everything I've tried, but lots of people like it.
