Perfect Barrel Size For 22 CreedMoor with Suppressor

My apologies for asking a similar question. I am going to get a Tikka T3X Lite 22-250 1 in 8 twist and have it rechambered for .22 CreedMoor. I am wanting to shoot with a suppressor. Planning on using a Banish Backcountry. What is the perfect barrel size? 18"? 20"? I want maximum light weight and ease of packing around. Will be using for Deer Hunting. Also will be using it for coyote and long range shooting as well. Thank you in advance.

Which suppressor?

Great question. Sorry I should have added that. I added it into my original question. https://www.silencercentral.com/products/banish-backcountry

I would choose the 20” with the Backcountry on first blush, but choose the length that keeps your energy and speed where you need it for the max distance you’re hunting. If they both make the mark, the shorter barrel is preferred.
