Questions/Opinions on 4350 powders - Page 2

I looked at the burn rate chart in the Lyman 4th edition SS manual, and the burning rates are: AA4350 fastest, then IMR4350, and then H4350. FWIW.

I made a spreadsheet with the burn rates from one of the Manufacturer's websites. It does not have some of the newer powders.

You can filter it by brand.

It has a macro in it that I used to parse the data. So you may get a virus warning.

I also have used IMR4350 under the Sierra 165gr Gameking for many years in my .06 bolt gun. Two years ago I switched to H4350, it takes a grain or two more for the desired results(velocity), but it meters so much better through my Uniflow that I'm convinced the consistency has improved the acuracy. And yes I weigh every charge for rifle re-loads.
