Several threads and trains of thought have brought me to what I hope is an interesting thought exercise: .45 Super and/or .460 Rowland performance from a 10”-20” barrel.
I’ve seen .45 ACP doesn’t gain near the performance boost from a longer barrel unlike other calibers like 9mm. But as best I can recall I’ve never seen numbers on the Super or Rowland from a longer barrel.
If anyone has seen or has actually done some testing I’d be interested if you’re willing to post it up.
Thanks!
