I just got a 24" barrel in 358 Win for my Savage model 11. My plan is to shoot reduced loads to cull small deer at 150 yds or less. In full power loads I know a shorter barrel means a greater blast but I have no experience shooting this caliber or heavier, slower bullets. I'd like to cut this barrel back to 20" to make it handier and lighter. Anyone have any experience with this? Thanks.
