Smoker*,

These are the simulation results:

Barrel length - 28"
Bullet seating depth 0.57"
Bullet - 360 gr Northfork
Powder - 55.0 grains of IMR4320
Expected muzzle velocity - 2165 fps to 2087 fps
Expected chamber pressure ~ 51,800 psi

Barrel length - 28"
Bullet seating depth 0.57"
Bullet - 360 gr Northfork
Powder - 61.6 grains of IMR4320 (~110% load density)
Expected muzzle velocity - 2326 fps to 2248 fps
Expected chamber pressure ~ 58,200 psi

Barrel length - 28"
Bullet seating depth 0.5"
Bullet - 360 gr Northfork
Powder - 64.1 grains of IMR4320 (~110% load density)
Expected muzzle velocity - 2404 fps to 2318 fps
Expected chamber pressure ~ 60,600 psi

Changing powders:

Barrel length - 28"
Bullet seating depth 0.57"
Bullet - 360 gr Northfork
Powder - 61.5 grains of IMR4895 (~110% load density)
Expected muzzle velocity - 2381 fps to 2303 fps
Expected chamber pressure ~ 59,800 psi

Barrel length - 28"
Bullet seating depth 0.5"
Bullet - 360 gr Northfork
Powder - 64.0 grains of IMR4895 (~110% load density)
Expected muzzle velocity - 2454 fps to 2375 fps
Expected chamber pressure ~ 62,700 psi

I have not shot the Northfork bullet, thus the velocity range ie the simulation is correlated to Woodleigh bullets.

Hope it is helpful.

Hey Ass_Clown,

Thanks a bunch!!! I will begin with the lowest powder weight and work my way up.

I'll let you know what kind of data I get as soon as I can get to the range.

Thanks again,

Smoker
