I run 26.5 grs of 15 in my Remington with 75's. 3,100 but its got a 24" tube.
Also needs bushed....
Reminds me,I should have another flat rate box here somewhere,with a freshly massaged bolt and threaded handle.
Midway was blowing out a bunch of bolt knobs,for like 6 Clams a pop and there should be a goodly herd of them either here,or enroute.
Generally takes a coupla days,for me to get all the mail sorted out............
