Hello Parashooter.
I have been running this QuickLoad today and to see if it was acting right, I ran the earlier mentioned 4350 loads with 220 grain bullets in 30/40. With the 41.5 grains mentioned that cracked a bolt Q/L shows that is under the 47,137PSI safe value but unknown tolerances may cause dangerous pressures! With 40. grains of 4350 it suggest to check loading manuals because secondary explosive effects are possible.

Switching to 35/40 it shows 47 grains of Varget to be a compressed charge and tolerances could cause dangerous pressures. No such warning at 46 grains, with 3300 FPS velocity, almost exactly half way between 30 Remington and 358 Winchester with a 200 grain bullet! I am thinking I will fireform one case at 40 grains and double check the water volume.
If all checks out I will use 46 as max and look for a load in the 42 to 45 range that is accurate and does not kick too hard. I weighed the completed rifle and right at 9 LBS, 1 pound less than a scoped 1917 Enfield.
