I agree that 760 is a great powder for extra energy and it meters nice and smooth. Also ball powders have a great chemical stability and will last longer in storage than any other type. Definately the powder for the survivalist or doomsday prepper , seriously .
I use it in my 30-06 AI and it gives good ballistics. However Varget , H 4895 and Benchmark are much better at resisting temperature changes than ball powders.
I am not concerned with tiny groups with the 30-06 however extra velocity is a good thing. If I am trying to shoot tiny groups then I would use H 4350 ( Eq to Aussie AR 2209) which is about the same in burining rate to 760 and H414 .
For general hunting there is many powders that will do the job just fine and one gun might love one powder and another gun hate it . We can't generalise with this kind of thing , one shoe size does not fit all.
