I guess I kinda phrased my question wrong, it was late, sorry. I was really more curious about at what level is the larger case head safe? Would it have to be loaded to 450 marlin levels at 42,000, or even lower because of the tapered case? In all reality, I was not considering rechambering for 300 H&H, I realize gains would be minimal, I was more curious about what the math said the pressure levels would be safe, the 300 H&H was just the first case I saw that was operating at lower pressures than a standard caliber when I was up late last night. Like I said, just curious really, sometime being alone late at night here makes me curious about odd things. Thanks, Billy
And as an aside, it had me thinking about the 500 S&W, which can supposedly be loaded to 60,000, but as I understand it the rimmed case has less internal area to produce thrust, and it is straight walled as well, so I do not know how much that affects it, but do most guys keep it loaded to lower levels to avoid any trouble that some seem to have had? Thanks
