In my 22" barrel I get 2966fps with 160gn Accubonds over 61gn of Rel 22.

My 7mm Remington propels 175's at the same velocity from a 26" barrel but the Ackley is chambered in a Featherwight Model 70 while the Rem is a standard Model 70 and a pound more in weight.

Thanks! That's what I was looking for. My 22" T3 7mm RM only did around 3000 with 160's (book handloads), so the 280AI looks pretty good there.

My one problem with the 7mm Rem Mag, as a handloader, was brass life; don't remember what brands I used but never got more than 3-4 firings before cases started to crack just above the belt.


you need to start sizing off the shoulder instead of the belt and your 7 mag cases will last much longer
