    I received my rifle from Mr. Spencer last week. I am goin to try some 4831 SC with 210 JLKs. What grain should I start? I thought about 60 grains. Any advice would be helpful.
    Thanks,

    I'm not BH but I shoot two 300 WSM's for 1000 yard BR.....What twist is your barrel???I would suggest you try some H4350 with the 210's..And I would start at about 56gr..

    like Boyd says, I would start with H4350. For some reason my gun like it better than anything else (MRP, MRP2, RL22). Have not tried the 4831sc in the wsm. Think you will find that somewhere in between 58-61 gr h4350 with either 190 or 210 jlk. Start .010-,015 into lands and work out after finding sweet spot.

    Note that I test my guns using the ladder method to find sweet spots and then final test off one of those spots. I do not need to push max velocity and have found out the hard way when you are right on the ragged edge, you can get good accuracy as long as the temp and humidity do not get high. If they do your load will go to hell fast. I stay back from the top end and my 300 is only pushing around 2900 with either bullet.

    Some guys have tried and found that their gun likes the 215 primers better than the 210. Also do not be surprised if the 190 shoots better than the 210 in the 300 wsm. I have shot my best and most consistent groups with the 190 and think I am going back to it next year.

    PS You will love Clays guns and I think his barrels are the absolute best of anything out there.

    Boyd, the barrel twist is 1-11.

    Bounty Hunter, I have a can of 4350 and 4831 and I couldn't decide which to use, so I flipped a coin. Saturday, I was breaking in barrel and fire forming cases with 66 grains 4831 and using 178 Amax. Extreme spread was good. Velocity in the low 2900s, groups were good. I have 190 and 210 JLKs to test. Reamer was built for the 210 JLKs. So I'm like you I want accuracy not necessarily velocity. You're right so far about Mr. Spencer's rifles; the barrel cleans up easy and it's smoooooth. With what I've seen so far, it's gonna be a shooter.
    Thanks, Taz
