GB, In these times of supply chain disruption, we gotta use what we got. But the whole point of using faster burn powders and lighter bullets is recoil reduction. Using your 150 gr bullet and a 7.7# rifle on 'shooters. com' recoil calculator as an example...a 46 gr powder charge, at 2750 fps will yield 16.6 ft lbs of recoil. Drop to 40 gr at 2700fps, you will get 15.05# recoil...doesn't sound like much, but it's a hair over 10% reduction. Develop a load with 130 gr Hornady, with small charges of fast powder and we are talking serious recoil reduction, below .30-30 levels.
In the recoil formula the powder charge weight is significant (called ejecta). Play with the formula, you will quickly see the benefit of reducing the total ejecta weight.
