I recently purchased a Remington 788 308. I dont have reloading equipment but know someone I trust to do it for me. Can anyone help me with a accuracy load using a 150 gr sierra spitzer? This is my first 30 cal. Any suggestions on powder? I Might have some IMR 4350. Is this a good choice or not? Thank you for any support
No one can tell you which load will be the most accurate in your rifle since all rifles are individuals.The only way to find out is to test your rifle with some powders with a suitable burning rate.IMR 4350 would not be where I would start if you want optimum velocity from a 308win.I would be looking at r-15,imr4064 or even Varget.
4350 is a little slow for the .308 and 150 grain bullets... Of course, it wouldn't hurt to try it...Your rifle might shoot it very well, but velocity would probably be less than optimum..
4064 is a classic for the .308, and as stubblejumper said, R -15, Varget and 4895 have similar burn rates andare good candidates also...
Thank you for the input. The reason I asked about the 4350 is because I shoot it through my 788 22-250. You know, trying to keep cost down. I think I will try something different with my 308. Just shooting factory for now to aquire some brass and of coarse get aquinted with my gun. I did like the 150gr. for all around performance but they werent sierra bullets. Thanks again.
My 308 accuracy load for a pre-64 M70 WIN. was 51.5 grains of H380 with the Sierra Gameking 165-grain HPBT. This is a hot load, but was very accurate in my rifle.

If you plan to give IMR4350 a try I would suggest magnum primers like215 federal. The magnum primers will decrease the effective burn time and increase velocity. I gain over 100 fps in my 06 when switching from 210 to 215 primers with 180 grain bullets. This should work in any case capacity limited cartridge.

Of course the extra velocity is a result of extra chamber pressure produced when using the 215s.You can simply use 210 primers,and add a grain or two of powder to achieve the same results.

That what I was thinking. Anywho, I have had horrible luck with 215's and 308. Velocity spreads up to 100fps with Varget and 4064.
