Okay.... I did not find H-110 a suitable powder for the .444 Marlin with any bullet weight, in either rifle or handgun. Load from a disk does not recommend H-110. Here is the data from Quick Load: **** Input data: Date: 20-May-2004 Time: 15:18:42 Cartridge................. = .444 Marlin Projectile type........... = .429, 180, Sierra JHC 8600 with flatbase Max.avg.pressure(Piezo CIP)= 51488 psi Shot start / init pressure = 2176 psi Projectile weight (gr)= 180 Groove caliber (in)= 0.430 Length of cartridge (in)= 2.548 Length of case (in)= 2.215 Case capacity(Grains Water)= 69.00 Length of projectile (in)= 0.583 Length of barrel (in)= 18.500 **** Values calculated: Seating depth (in)= 0.250 Volume displaced (gn H2O)= 9.18 Comb.chamber volume(gn H2O)= 59.82 Projectile travel (in)= 16.535 **** Input data: Propellant type........... = Hodgdon H110 Charge weight..........(gr)= 55.0 Load density......(g/cu.cm)= 0.918 Heat of Explosion (cal/lb)= 445279 Ratio of spec. heats cp/cv = 1.220 Solid density (gr/cu.in)= 409.7 Weighting factor.......... = 0.8 Burning rate factor Ba(1/s)= 0.794 Pro-/degressivity factor a = 5.217 Burning limit ......... z1 = 0.3 Combust.Chamber Vb(ft�)= 1.371435E-4 Factor.................. b = 1.833 X-S.Area of Bore A(ft�)= 9.959076E-4 Bulk density (gr/cu.in)= 247.3 Projectile mass mp (lb)= 2.571385E-2 Loading ratio (%)= 93.8 Projectile travel x(ft)= 1.377923E+0 **** Results calculated: Maximum pressure ........ = 56254 psi Way of projectile at Pmax = 0.92 in Muzzle velocity ......Ve = 2884 fps Muzzle pressure ......Pe = 5823 psi Project. energy at muzzle = 3325 ft.lbs Fraction of powder burnt = 99.9 % Projectile travel time from 10% Pmax to muzzle = .8 ms D A N G E R: Load exceeds Maximum Average Pressure ! DO NOT USE THIS LOAD ! | |||

And here is the data for his 60 grain load... **** Input data: Date: 20-May-2004 Time: 15:24:44 Cartridge................. = .444 Marlin Projectile type........... = .429, 180, Sierra JHC 8600 with flatbase Max.avg.pressure(Piezo CIP)= 51488 psi Shot start / init pressure = 2176 psi Projectile weight (gr)= 180 Groove caliber (in)= 0.430 Length of cartridge (in)= 2.548 Length of case (in)= 2.215 Case capacity(Grains Water)= 69.00 Length of projectile (in)= 0.583 Length of barrel (in)= 18.500 **** Values calculated: Seating depth (in)= 0.250 Volume displaced (gn H2O)= 9.18 Comb.chamber volume(gn H2O)= 59.82 Projectile travel (in)= 16.535 **** Input data: Propellant type........... = Hodgdon H110 Charge weight..........(gr)= 60.0 Load density......(g/cu.cm)= 1.001 Heat of Explosion (cal/lb)= 445279 Ratio of spec. heats cp/cv = 1.220 Solid density (gr/cu.in)= 409.7 Weighting factor.......... = 0.8 Burning rate factor Ba(1/s)= 0.794 Pro-/degressivity factor a = 5.217 Burning limit ......... z1 = 0.3 Combust.Chamber Vb(ft�)= 1.371435E-4 Factor.................. b = 1.833 X-S.Area of Bore A(ft�)= 9.959076E-4 Bulk density (gr/cu.in)= 247.3 Projectile mass mp (lb)= 2.571385E-2 Loading ratio (%)= 102.4 Projectile travel x(ft)= 1.377923E+0 **** Results calculated: Maximum pressure ........ = 75738 psi Way of projectile at Pmax = 0.78 in Muzzle velocity ......Ve = 3104 fps Muzzle pressure ......Pe = 5981 psi Project. energy at muzzle = 3852 ft.lbs Fraction of powder burnt = 100 % Projectile travel time from 10% Pmax to muzzle = .71 ms D A N G E R: Load exceeds Maximum Average Pressure !
