There is nothing wrong with 3031 Powder !
Mike Walker,Head of the Remington custom shop for many years, inventor of the .222 Rem & .222Rem Mag as well as Multi champion Bench Rest Shooter, told me "the accuracy test load for the 22-250 Rem Cartridge was 33 Grains of 3031."
I have used it in many cartridges, but the load which I find the most impressive is 53 Grains under a 400 gr Speer Flat point,for well over 2000 fps in my Straight Grip Marlin 45/70 !
That is energy !!
Some guys at the Gun club ask to shoot it, but they never want to shoot it twice !
