.338 Edge Improved?

Thanks guys for some information and some laughs. I have a 7 mm on a 338 rum and I use 7 mm rum brass to get that longer neck. BUT I have to trim after every shot. Therefore, I want the 40° improved shoulder to prevent so much trimming on my .338 Edge improved.
 
I do remember some magazine writer sued Winchester and Remington for their short fats.

I'm 80 and did one when I was 39 years old. I took a 378 Weatherby and shorten it to 2 1/4", necked it down to 7mm and called it "Short Fat Seven. Later I discovered Dan Lija did the same thing but he made his 2 1/2" Long for the case.
 
I don't think there's much to be gained by improving it via shoulder angle and case taper. I did a 375 RUM-Imp and also moved the shoulder ahead I gained about 6.5gr of H2O capacity

If your just after reduced trimming look at 338 RUM data should be really close. I found about 3150 with a 215.

REDUCED LOADS? That's against my shooting religion.

I'm a small guy with a Napoleon complex. My psyche requires a light rifle with a big cartridge and a big scope and a big brake to compensate for my Napoleon complex.

338 RUM and Edge are so close it's silly. Load 'em however you want.
