I reloaded several of these for friends of mine--the last load I did was using a 150 gr Swift Scirroco...pressures were very safe and chrono'd the load at 3170 fps...know I could push it faster than that..but with temp extremes he uses if for here in Montana..anywhere from 80F for antelope to possible -20F for elk...so kept the pressures mild..would guess you could safely get 3000fps or more especially with a 26" tube --the velocities I quoted were from 24" barrels..

I also rechambered a lightweight rifle by Lex Webernick (Rifles Inc)..that was in .280 Rem. to a 280 Ackley Improved..wish I had done that sooner..anyway, shooting 140's out of it at 3200+..
