I was thinking of trying the 162gr but wasn't sure if there could be stability issues with the slower twist. I remember using them many years ago in a 7RM Browning A-Bolt and the accuracy was amazing with H870.
Yes, as soon as I seen it I had to snatch it up haha. Good to know the DOM, thanks. I wasn't originally sure if it was actually an Accumark or one of the ULW.
This is actually the first 280 I have ever owned. And it's a Weatherby Accumark which is not a common chambering I'm thinking. Will mostly be for whitetail deer, so was thinking of trying some 140gr BT. Always had great success with them on deer. Might have to pick up some IMR4350 as well.
Just acquired a 280 and was wondering what powders folks have used? Currently have H4831 and since it has a 1-10 twist, was thinking 140-160gr bullets.
Got out to the range today to test some more loads and things seem to be coming along pretty good.
Two loads broke 3/4" using the Hornady 100gr BTSP and H4831. The larger group was 52.5grs and the next one is 53grs.
Unfortunately I didn't pay attention to which shot went astray. I will try the 4 shot group. I'm also going to check stock and mounts torque. Got some other bullets to try as well. Nosler 90gr BT, Hornady 100gr BTSP and some Speer 90gr SP.
Tried H4831 with the 85gr TSX. Not sure if it was me on that stray shot. It was pretty cold and my hands were freezing lol
The other group with the stray going the other way was with Speer 100gr BT and H4831.
I have owned and shot most of the Bee's and the worst so far was an older Japanese .378 with no brake and a lighter contour barrel. Just plain nasty from the bench. Even an older Pendleton braked .460 firing the old "elephant" box factory ammo wasn't near as bad. Still gives me nightmares.
Got my eye on a nice Mk V Safari and was wondering what a good powder would be for 350-400gr bullets. Alliant powders seem to be almost impossible to find these days, so RL22 might not be possible.
Just picked up some 120gr A-Frames to try in my .264 and was wondering if anyone had access to Swift data? If they perform well, I will buy the manual lol
