I could have killed most deer with a 22lr. And would have if legal.

That said you can't just assume pressure is safe vs speed. I mean you can find load data for modern rifles and speed is relevant to pressure every time.

Even a milder loaded x57 will kill stuff all day long.

The fascination with another 100 or 150 FPS never ceases to amaze me. Had one friend pushed a 25-06. He loaded "safe" but hot ammo. Eventually the lugs beat the recesses back enough he could not unlock the bolt. We had to remove the barrel. Safe. I'd say not. Lucky is more like it.

Getting same speed as cartridges with more powder capacity for the most part is scary to me.

We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
