Just because a rifle's destructive testing has shown it will take 100K psi doesn't mean every action or piece of brass in that cal. will take anywhere near that much pressure. Normal proof loads are about 30% over normal running pressure and that's it. The 7rem is a bad cartridge running at lower pressure than many of the designs are capable of. But there are rifles in 7rem that do NOT have the headroom to play with extremely heavy loads. Not to mention the fact that the higher pressure you run the rifle, the faster the throut wears and the more action wear you will have and I don't care if you have a bolt or falling block.
In short get a bigger gun if you want to run with the bigger guns.
Anyone who would take someones load off the internet and use that as there starting point.....well do I really need to say anything?
I give people a little more credit then that.
I just worked up a load. 66 gn IMR 4831 162 gn Amax Nosler brass CCI 250
another one is 69 gn H4831sc with same bullet. I haven't cronoed either yet but what I have been shooting is 67 gn IMR 4831 160 gn sierra for 3140 fps
I do not load for velocity. These loads are what my rifle shoots most accurately, With absolutely no pressure signs. Depending on what book, I'm 3 to 4 gns over their published Max. I did start at the min charge weight.
That's funny, I just checked, I'm in 7mm rum published territory. Who knows if I had a rum I'd might be off the charts, if that's what my rifle dictated. I do have rifles that are loaded below the max because that's what they shoot the best.
