Sycamore: I use a fair amount of H 322 - its stayed "consistent" for me over several decades now.
4 of my 6 Varminters in 222 Remington prefer (accuracy wise) H 322 and 1 of my 2 Varminters in 22 Remington Bench Rest prefers H 322.
Also my ultra-accurate factory stock Remington 40XB-BR KS in 6x47 is MOST accurate when using H 322 powder.
Best of luck in your load development.
