Winchester Supreme 180gr Accubonds - shot 2920fps.
Nosler Custom 180 gr Accubonds - shot 2720 fps (which I was a little suprised)
The Nosler grouped .5" at 100 yds - the Winchester grouped 1.1" at 100 yds. Most of the shooting on this trip will be 300-400 yds. (about 3" different at 400yds according to the ballistic calc - but 200 lower K.Energy).
Is that too slow in you opinion? I guess I like the accuracy and feel I can place it better.....but want enough juice behind it as well.
If you don't have time to hunt for other ammo I would go with the best shooting ammo.
2720 ft/sec is slow for the WSM but that's plenty fast for shooting 400 yards.
The Winchester supreme velocities are going to be hard to beat in a factory load because
the use proprietary powder that was developed for the WSM and cannot be purchased
by any other ammo manufacture. so don't expect any other brand to reach the velocity of
the Winchester brand In the WSMs.
Most Weatherby ammo is hard to duplicate for the same reason.
