I realize that every rifle is different and that loads need to be developed but I would like some ideas of where to start. Buying many different bullets and powders gets expensive.

My goal is an accurate hunting load for big game ( deer pretty well, won't be shooting moose or elk ) The rifle is an m77 mk II in 308 win. with a 22" barrel and I would like it accurate to 300 + yds. If anyone has some good bullet and powder combos to look at that would be great. Especially if they involve IMR 4831 because I have a pile of it right now.
 
4831 is on the slow side for .308 case. You would likely be able to work up an accurate load but might not realize the full potential of the case. Something along the line of win 748, imr 4064, varget, etc would likely give better performance.

Good luck, 44Bore
 
get your Ruger bedded and the trigger turned down to a nice, crisp pull

then load some 150 gr. Nosler Accubonds over some Varget or RL15, in Lapua brass and lit off with Federal 210M primers.

that might work

Sunray is correct.

I have a Ruger MKII in .308win and it is very fond of IMR 4064 with 165gr Sierra BTHP. It will shoot pretty much any 165gr bullet well, but it really likes the Sierras. I use a charge weight of 43.5gr which shows no pressure signs in my Ruger.

I don't shoot 300yards with it, but it groups well at 100 metres and 200 metres.

Good luck.

i would be trying reloader 15 or varget. these powders seem to give good acuracy and velocity. i would try one of the bonded 150 to 165 grn. i like swift scirrocos, a little pricey but very accurate.
 
As suggested, start out with a 4064ish powder, and you know what? Some people might suggest you don't need the bestest, most expensiviest, premium bullet out there in a 308, if your budget is limited. Interlocks, hot-cors, gamekings will likely allow you to shoot more and become a better shot, and will perform nicely out of a 308, especially on deer at reasonable distances. But don't let that stop you from going premium if you want to.
 
I would suggest a 165 grain to 170 grain bullet and:
N-550 From 40.7 grains to 48.9 grains
Remington 9-1/2 Primer

However, if you are stuck with IMR-4831 and with 165 to 170 bullets:
IMR-4831 From 45.0 grains to 51.0 grains
Remington 9-1/2 Primer
