Many comparisons between .22 & .25 use "similar" length barrels, but a 2" .25 and a 3" .22 are not really similar. The 3" bbl is 1/3 longer than the 2". The shorter the barrel, the more difference even a little length makes in velocity.
The difference in a 16" barrel and an 18" barrel may not be much, but when you get down to 2 inches, even 1/4 inch makes quite a bit of difference
In this test the advantage was to the underdog, .25ACP. The difference in barrel length was only 1/4 inch, which IMO is close enough for this test.

Bigger hole in wood doesn't automatically mean bigger hole in flesh, organs and muscle. And it definitely doesn't mean a better hole
But when you consider these projectiles are moving at almost the exact same velocity, I believe the larger of the two will have the advantage. Either way, I do believe it will make a larger hole through bone.

And thanks Andy!
