I am in need of info like this also . . . I am going to be muzzleloading for Elk in Colorado and they don't allow for saboted bullets so it looks like a PowerBelt and I was looking at the Platimum series in 300gr. Anyone have any info on this bullet?
Better make totally sure of the legality of the Powerbelt in Colorado. The last I heard, no plastic skirt was allowed which would eliminate that bullet. You may have to shoot something like a Thompson/Center Maxi Ball (a great bullet) or a patched round ball.
Powerbelts are legal here in Colorado, so shoot away!
I think if you are looking to elk hunt the perfect bullet might be the Accubonds. I like the Barnes Triple Shock but they dont have a flat trajectory like the others. For long range shooting you will find that these bullets tend to drop lower than others. The GMX line seems to be a flatter shooting round on paper but I have not shot those yet. Although they look extremely similar to Triple Shocks. On the other hand the Accubonds shoot extremely flat and you can hunt anything from thin skinned to thick.
