    Default Heavy 308 loads

    Looking for bison legal 308 load. Regulations require a 30 caliber 180 grain bullet that generates 2800 foot pounds. Buffalo Bore sells 308 loads that make it so I know its possible. Does anyone have any info on handholds that will do it???

    Looks like anything going around 2650 or a little better will do it according to my information.

    The factory Federal Premium 180 partitions in the red box are close. If you could get a shade hotter you could do it.

    Years ago, Lanche and I headed to the range running a gamut of 200 grain 308 bullets over the chronograph that met the legal requirement for bison on the Alaska side of the regs.

    Depending on barrel length, 2450-2550 fps was the norm for everyone running mr-2000 powder. 46-47 grains was the sweet spot for max loads for three different handloaders. MR-2000 gave less deviation in velocity over reloader 17 for some folks:

    I just looked on the Delta Bison Hunter Orientation and it says a 200g bullet with 2000 FP. Where are you hunting?

    In Yukon Territory the minimum load is a 180 grain bullet at 2800 ft pounds. Basically designed around the 30-06 as a minimum. 308 might make it loaded heavy and with a long barrel.

    Got it. Much more simple then.

    180 TSX to near maximum. Get all the weight retention you can out of the bullet and go kill stuff.

    If you can't shoot those long TSX bullets, then get some Aframes and then go kill stuff.

    If I was going to use a 308 for Bison in the Yukon I'd chronograph my loads on Video and present the information to the folks on Burns Road before venturing out. Arguing with enforcement 50 miles in about a very marginal caliber that can only make it by hot loading would possibly end up with a confiscated firearm, an ongoing dispute and a ruined hunt.

    How the heck do you enforce such a rule?

    Yukon,

    I sent you a PM. The load I sent isn't by any means a recommendation, it's just to show that it can be done. Work up to safe levels in your rifle.

    You mean an 06 or a 300wm.... 😁

    As no one carries a chronograph on a Bison hunt I believe it's more of a list thing. I'd be worried a 308 would cause trouble no matter how hot it was loaded while a 30-06 with a mild loading would generally pass muster. You might win in the long run but it could get ugly. Who needs it?

    As mainer mentioned above we did some work ups with RL-17 and 2000-MR powders and 200 grainers.

    I found I got better velocity and accuracy with RL-17 and 200 grainers in my .308. Was able to get 2550 fps with my 20" barrel .308 with 200 grain partitions and RL-17 powder.

    But 2000-MR was better for 180 grainers in which I was able to get 2650 fps with the same 20" barrel.

    Hope that helps.
