here is the rifle and specs

http://www.ruger.com/products/HawkeyeCompact/specSheets/37137.html

i am attempting to work up a load to match federal 55g bt. the box says 3240 fps

i have these powders, blc-(2), benchmark, 3031, h335, h4895, imr4064,imr 4350, imr3031, win 760 and 780

i am using br4 primers and federal casings.

my first work ups consisted of benchmark, blc2 3031 and h335. blc and benchmark shot ok and i think blc and benchmark had the best group. i wasnt shooting in the best conditions and didnt have a very stable rest (ammo can). i was trying to match the federal factory rounds but only one load (benchmark 25.6g) says it shoots around 3240 fps. def had a nice flame shootin out the end but no signs of pressure on the primers. i know the short barrel has some to do with this i just dont want to fry the rifle
