I would appreciate getting feedback on what would be the minimum barrel length that would work well with a 22-250. I'm looking at getting one for coyote hunting and want a light weight gun. I see that Sako makes one that's a mere 5lb lbs. It only has a 20 1/4" barrel (1:14 twist) and I'm wondering if this would be too short to get reasonable performance from this cartridge. Thanks.
