    150 Sierra gamekings and varget powder


    I have a staggered feed savage 16 308. I bought varget powder and 150gr Sierra gamekings. Has anyone else used this combo? How much powder and what overall cartridge length has done best?

    Try from 46.0 to 47.5 gr of Varget with Winchester brass. I seat them at 0.020" from the lands which is a COAL of about 2.925" in my son's factory sporter barrel. 47.0 gr is right at 2850 fps in his 24" barrel. Sub-1" at 100 all day long.

    I know this is higher than some load tables list as max loads. But the Hodgdon site goes to 47.5 gr as a compressed load.

    Luck, Tim

    I don't know exactly what length I should use for the coal. I used an empty cartridge and seated the bullet just enough to hold the head . The I chambered it and measured it afterwards and got 2.86 for a chamber depth. Anyone else use the meth?n how accurate is it?

    I take a case and cut a slice length wise in the neck with a Dremel tool. I run the brass through my FL size, then lightly seat a bullet in the neck of the brass. Then chamber. Slowly open the bolt and push the round back with a cleaning rod from the muzzle end. Take the measurement 3-4 times with 3-5 different bullets. Personally I make all my measurements at the ogive with a Stony Point tool. A lead tip like the SGK will vary +0.025" or more in the same box of bullets.
