Well, there ya go- the 12 bore runs from light loads in the .308 recoil range up to in excess of the .458 mag in the 3" category and 2 oz loads.(over 55lb.) I merely picked a heavy 2 3/4" load. The 1oz slugs I just bought are rated at 1,700fps with about 28lb recoil, probably in the 150gr. .300 mag range.
: Atempting to rate recoil with no information other than a 12 bore load, with it's extreme recoil range, and with rifle rounds also having large recoil ranges depending on loads, especially with Hornady's 'light' 'women & kid's loads" is a very difficult task. What loads does one use? Pick the lightest laod out there, or a medium one which would be similar to your .330 mag?
: I call the Ultra Mags ridiculous due mostly to their outrageous powder charges and wayyyyy overbore capacities. When the .300 mags are already at or over max for the case, burning an extra 25gr. of powder just seems a bit foolish, but then, some people will do anything to get a few more fps. I guess that's why some people neck the old '06 down to .224, or .378's down to .30. The fps race just seems foolish - it is never-ending with companies trying to milk every last penny from customers.
: Yes - that's my opinon and I'm within my rights to give it - at least on an American web site.
