I have only used heavy projectiles 140 -143grn so feedback relates to these.
I had a 30 inch barrel and 2213sc was my choice.
I had the barrel turned down from a #5 to a #3 and cut to 24inch and have moved to 2209, it’s still a tac driver.
Short answer, rocking horse shit would be the preferred powder.
I run 50grns of 2209 pushing 143 eldx just over 2900fps
