Depending on what I available I use IMR 4064 using 47.9 grains of powder Federal 210 primers and the 165 grains BTSP hornady. I don't go for velocity but for accuracy. I also use reloader 15, same bullet and 48.3 grains of powder same primers.
What test rifle did they use in this latest edtion ?. In the nineth edition they list max charge max charge for IMR 4064 at 50.2 Grains vs 51.9 grains in this latest edition. Not a big difference butt still not the same...
Same wording and rifle in the 9th edition but didn't list IMR 4350 in this 10th edtion , strange. Thanks! for posting Lennyjoe.
With a 165/168gr bullet my most accurate load is 57.0gr IMR4350.
