txpete,
On the closest bullet I have to yours, the 362 grain NEI GC, the 31.5grs of 5744 gave me and avg mvl of 1591fps with extreme spread of 29.70 fps and a std dev of 17.02 fps. That's in the 32" BC so with your Marlin with the 27 grains of 5744, I think you've picked a winner. I'd speculate a mvl of 1400+ fps or so. But more than that, I'd look for some unexpected accuracy. Oh btw I used CCI BR primers which are really the same as the CCI 200 standard LRPs When I went to the Federal 215 MLRP's in an attempt to get more efficient burning with the 5744, avg mvl went up some (1614fps) but there was still unburned powder. But with the superb accuracy I got (with the Feds as well as the CCIs), I figured I could blow out a few powder grains. I don't know if it'd cause trouble in your lever or not. Just have to see I reckon.
Be looking forward to your range results
:wink:
