I want to try some 162 gr. A-Max bullets in my 7mm Weatherby magnum, but the box says a 1 in 8" twist. Really? Is anyone using them in a 1in 10"? I normally use Berger 168 gr. but they are not always available at my store of choice.
 
I use them exclusively in my 7MM Rem Mag and have great success.
I believe my rifle has twist rate of 1:9.5 and these bullets group nicely at 100 and 200, I push them out a 24" barrel around 3000fps with IMR4350 and have used RL22 as well.

I've used them on Black Bear, Deer, Grouse, Sheep, all one shot willies.
I would have used them on moose but didn't get the chance.

My 280 has a 1:10 twist rate, but still haven't loaded any of these bullets it for it yet. I'm pretty sure they would work tho.
