If you can get a copy of Walter's CAD disc, I can get you some free time on a friends CNC machine this fall.

I have found a load:



Varget 81 grains

400 grain Woodleigh RNSP

Norma brass

GM215M primer

Ave. vel. for 3 shots = 2401 fps

SD = 3 fps

ES = 6 fps



This is about a 95% load density with this bullet and powder.



My best guess of pressure is < 51,000 psi.



There is room to use 400 grain Swifts and TSX's with no worries of compression.



Saeed gets higher velocities with his banded monometal 400 grain Walterhog.



I would too if I had such a boolit.



BTW the max load I tested was 84 grains of Varget, giving 2490 fps in my gun.



I think my 81 grain Varget load has great potential for any 400 grain bullet.



I might even add a dacron filler to prevent any shake of powder granules whilst bouncing around in travel. It is unseemly to grind your powder down to a faster speed down the road.
