Short barrel magnums

[WKR]

I'm used to longer barrels on my rifles but my next rifle is a 20" 7 prc and I'm curious if the powders i have on hand will work or if because of the shorter barrel a faster burning powder might be more effective and for a more full powder burn. I have plenty of H1000 and rl22 but they are both slow burners. Anyone have some knowledge to share on short barrels and slow burning powders?
Maybe I'm over thinking it But I always notice the unburned powder in my short barreled pistols when using a powder like accurate #9, and I wonder if that carries over into the magnum rifle world.

Barrel length doesn't matter. Burn rate for caliber is what matters.

You will be fine with both of those powders in a 20” 7PRC
