My go to 44 Mag deer hunting load for years has been 240 gr XTP with 23.5- 24 gr H110. Been shooting it for years out of a Ruger carbine and shoots great. shoot them out of a super blackhawk also with no problems. I recently borrowed a friends chronograph for other rifles but thought id see what these where running. For some reason i grabbed my Marlin(REM) ss 1894 and shot 3 rnds. all three where so tight in the chamber after firing i couldn't hardly work the lever. primers seem a little flattened but not horrible. Chrony read all around 1700fps...My first thought being i loaded this batch with to much powder. pulled a couple and they are all at 23.8. Coal is 1.60". is the barrel tighter in the marlin? is this normal? thanks SB
