Ruger Mk3 hunter fps vs barrel length question

[problemchild]

I am looking for this gun.
KMKIII512H with a 5.5" barrel


I happen to find this one with a 4.5 inch barrel How much fps will that 1" cost me?

In the VOL. 9, NO. 4 issue of GUNS & AMMO magazine, Bob Milek wrote an article titled: BARREL LENGTH VS VELOCITY, where he took a number of barrels and guns and cut down the barrels in one inch increments, measuring the velocity loss at each step of the process for a number of centerfires as well as the 22LRs. It's a very interesting article. Here are the velocities recorded for the 22LR starting at 14 inches and going down to 4 inches.

14" = 1,105 fps.
13" = 1,106
12" = 1,110
11" = 1,089
10" = 1,114
..9" = 1,077
..8" = 1,063
..7" = 1,057
..6" = 1,024
..5" = ..959
..4" = ..927 fps.

Thanks looks like 4.5 to 5.5 would be aprox 30-40 fps.

I bought a 6.88” barrel Hunter for the accuracy not the fps necessarily but every little but helps. Did you check Buds lately for that handgun? Two weeks ago Buds had a number of the 6.88” Hunters that’s when I grabbed one as it appears Ruger is going to be slow to get out MKIII models for awhile.
