    what is the best load for AR10 308win with Varget on the 18" SASS 1:10 twist barrel. The bullet is Hornady 165Gr. InterLock BTSP.

    Start at 42.0. Work your way up in small .2 -.3 grain increments. Max is 46.0, which yields a compressed load, and is a bad prescription IMO.

    Consult a good load book. There is no "best load" for any rifle, only the best load you can derive through trial and error. If you use military cases, drop your loads by 10%.

    Asking for load data on the interwebs from people you don't know is a recipe for pain.

    Good luck!

    ^truth.
    It will vary by rifle.
    Same make and model, no 2 just alike.

    Mid range loads generally shoot the best but you have some testing to do.

    Exactly.

    I got rid of my .308 before I started using Varget, so I can't offer a suggested load, but I can say that I found quite a bit of difference in accuracy with loads 0.5 grains different. The .308 seemed to be much more susceptible to that than the .30-06, but I don't know how much is because of case volume and how much was just the particular rifle. Set up some loads and test until you find a sweet spot. (A .308 can be extremely consistent when you get the right load.)

    Like previously stated, every rifle is different. One of my 308s, a Remington 700 AAC-SD with 1:10 twists seems to hate Varget. But H380 shoots good in it.

    I won't quote my own powder charges online but perhaps the following might be on point. It's quoted from Zediker's Handloading for Competition:
