max load under 140 gr. Hornday in a 22" 7mm-08 will run 2917 fps

max load under 140 gr. Hornady in a 22" .280 will run 3004 fps

max load under 140 gr. Hornady in a 22" 7 RM will run 3206 fps

max load under 140 gr. Hornady in a 26" 7 RM will run 3342 fps

all calculated using optimum powder for velocity and SAAMI pressures.

probably about the same diff @ 24" and 26" but i don't care enough to run the numbers. still, i see 200 fps as a healthy step up.

this suggests you will loost 34 fps per inch of barrel in the 7mm RM when going from 26" to 22"
