Home Forums Hunting & Shooting Single Shots Velocity gains from 26 and 28 inch rifles

Lee........I would guess a gain of around 20 fps per inch. A 50 fps (per inch) difference is a little too much and certainly a 100 fps (per inch) difference, is way too much with most cartridges.

The only way to know any accurate differences is with some side by side chrony reading comparisons.

Your previous experience with your 30" barreled 30-06 vs your 22" M/70 imo, should be a pretty good indicator of what to expect (per inch) between the longer barreled single shots and the 22' to 24" bolt actions.

The shorter 8" of barrel length with your 22" er, resulted in a 150 fps loss when compared to your 30" 30-06. 150 fps divided by 8" = 18.75 fps (per inch).

So, I`ll say and stick with, that about a 20 fps increase (per inch) is very realistic, given of course the same identical ammo or reloading components are used.
