for a bolt action................
If you shoot a GI issue M1 the powders around 748,4895,4064 are better for this gas operation rifle operating system. Slower powders may damage the system unless you get a special plug to change the gas pressure given off by the slower powders.
In my 1903 rifle H380, 4895,Varget and 4320 gave the best accuracy with several types of 150gr bullet styles.
The heavier 165gr did ok with these powder but 4350 and a starting load of 4831 for 2530 fps joined the party with Speer, Hornady and Sierra bullets.
Most shoot the 180gr at factory speed and 4350, H414 and 4831 worked with a little messing with primers, the same with the 200gr boat tail by Sierra.
Most loads were with the cci 500 and 550 primer but in the heavier bullets I found that my rifle got BETTER groups with the Winchester standard primer, something you might want to try.
I did get a light 180gr load with imr4350 at 2430 fps that grouped 4 @ .99 at 100 yards with the win. primer and this load only had a recoil of 16.3 ft/lbs vs the factory load kick of 19.1 ft/lbs at 2660 fps with my Fac. Dup. loading that placed five shots at .84" at 100 yards
For most bolt actions you can't go wrong with powders that burn around imr4350 with a touch of H or imr 4895 as a back up powder.
Good luck and stay safe.
