Man, I need some AA-2230 to get a solid 2450 fps with the 450gr TSX's Ron, have been on the lookout, and no Sir, I haven't shot any coated bullets in my rifles.
gunner500,
I learn from you. I am going to go back to AA-2230 and use a shorter COL like you did with the 450-grain TSX": 3.565" instead of 3.680" You must have noted that 83.0 grains of AA-2460 is a full load and got you only 2418 fps from a 24" barrel. BUT YOUR PRIMERS WERE NOT FLATTENED. We need a slightly faster powder to get pressures and velocities up, aye. I will SWAG again, I think AA-2230 is just a form of AA-2460 in which a certain percentage of the perfect spheres of AA-2460 have been flattened. The flattening allows greater weight of powder to fill a fixed volume with the AA-2230, and the flattened balls produces greater surface area of the powder so it burns faster.
And I learn from you as well Sir, agreed, AA-2230's slightly hastened burn should indeed give a full 2450 fps from my 458 Win Mag+, don't know why that figure is stuck in my head, 2415 fps would slay any creature out to a long 300 yards anyone would send a soft point bullet in to, the AA-2460 load would be perfect for 110 degree buffalo hunting, the primers are so round, with cases falling from the chamber, gotta be on the low end of sammi spec.
