You need to try them for fit & accuracy. That's the best way to find a good bullet. What works well in gun built one minute after yours - on the same assembly line -- may not shoot anywhere near the same target holes sid-by-side.
There was never a more true statement. My brother, a friend, and I have identical 50 caliber T/C Omegas (3 guns). They all like different bullets and powders. Both of theirs shoot 777 accuratedly, but mine will not. I even sent it back to T/C and they got great groups out of it with sabots (I can't shoot sabots in Colorado). I had to go back to pyrodex to get accuracy with mine.
Each gun is different! There is NO "best" load for a group of guns, you have to experiment at the range with YOUR gun.
