Both guns stabilized all bullet weights equally at the velocities represented in the accompanying data table. In no case was there ever a bullet that failed to deliver acceptable to superb accuracy in both guns except for the 44-405g WLNGC. Most times this accuracy level was achieved with differing powder charges and or powder selections, but none the less, no bullet performed to a less than acceptable level... for the exception of the .44-405g WLNGC bullet. This particular bullet stabilized just fine at all tested velocities in the 444P "Outfitter" model with its 1:20" rifling twist; however, in the 444S model with it's 22" Micro-Groove 1:38" twist barrel failed to stabilize the 405g WLNGC bullet at all velocities that were developed within uniform safe operating pressures. At velocities under 1950 fps. this long bullet tumbled and keyholed in the .444S's 1:38" twist barrel in every instance. However, once velocities exceeded the 1950 fps. threshold, the bullet remained stabile out past 100 yards, in order to generate these velocities pressures exceeded the limits of safe and sane operation for the .444 Marlin in these guns, and that data will not under any circumstances be made available. The 444P "Outfitter" model with 1:20" twist in its 18.5" ported barrel stabilized the bullet very well, and it remained so out to a distance of over 200 yards!

The bullet range he reffers to is from 325gr to 405gr. and all lead projectiles were .432 in diameter versus the normal .430
