Greetings,
A few years back I did some load tests using 125, 150 and 165 grain projectiles and several types of powder. AR2206H gave good results as they all did. The test load was 44 grains of AR2206H with the 150 grain Hornady Interlok in new Winchester cases and Federal 210 primers. Only two shots per powder projectile combination as comparative velocity was the aim. Velocity was 2,675 from a 20" barrel so a book max load of 45.5 grains should produce around 2,750 fps in my 40 plus year old M700. My rifle does not shoot the 150 grain boat tail projectiles as well as the flat base but your results may differ. I also tried AR2206, which is a little faster then AR2206H plus IMR4064 and AR2208. The latter two will need powder compression to get to max loads as they were a lot slower than AR2206H.
Regards Grandpamac.
