Seems to me the difference would be insignificant when shooting at something. Paper, game, neighbors dog . . . (lol!!!) (Really . . . I LOVE dogs!!)
I mean, no matter what you're shooting, you still need to cover holes with holes in paper. That way you know exactly where your gun is shooting.
If the muzzle velocity is different by a 100 fps or so, what does that really mean out 200 yards? 1/8", 1/16", (or less)???
See what I mean? Insignificant. There are more features on a rifle that I look for than an inch or two of barrel length. Action, stock material, barrel, action material, adjutable trigger, etc.
