I want to use accubond 260gr. in a #1 tropical .375 and I would really like to use IMR 4350. Other powders are likely better but I have a bunch of the 4350 on hand. I would like a fairly heave load as it will be used for moose in the open at 200 to 300 yds. Sure would appreciate some help.

My Nosler Reloading Guide 5th Edition, lists IMR4350 with the 260 gr solid base and BT. Partition and the 270 gr CT Fail Safe as follows:

Start load: 75.5 gr @ 2570 fps and 89% load density.

Max load: 78.5 gr @ 2747 fps and 94% load density.

The 75.5 gr load was designated the most accurate.

Perfect--thankyou--now I have a place to start.
