Now, We are back to something Bigger than the 270 Winchester....Thoughts??
Recoil is a function of the physics of mass x acceleration. There is actually a free recoil calculator on the JBM site
Here You may want to run some numbers
Bigger than a 270, smaller than a belted magnum. 280Rem, '06Spr, 284Win, or maybe a short magnum.
You may want to look at a 284Win built on a short action. It can push 140 or 150 class bullets a bit faster than a 7-08, probably in the 3000FPS range. The rifle will be more compact and lighter on the short action, and the recoil should be manageable. That said, my 7-08 gets an honest 2900+MV from 140 Accubonds. I'd bet it would get the same from the 140 Partition. I wouldn't hesitate to shoot that at an elk inside of 300 yards, and it's still carrying 1500ft*lbs all the way to 350 yards. We all shoot the gun we have because we like it. I think the 7-08 hits a pretty sweet balance in a hunting rifle. Now, is it better than a 270, ehhh? (would I carry my 7-08 out west for a hunt, probably not, I'd grab the 7mmRM because it is there)
In order to push the 30 caliber bullets that are designed for big game you may have to get to a heavier bullet and more recoil that she will want. Just the physics of shooting heavier 30 cal big game bullets will probably rule out a 30, but that's up to you and her. If you really want to get a 30 Cal then look at the 308 and the 30-06. Those are your steps. The 308 will work great with 165 class bullets, but with a bit more recoil than the 284s shooting 140/150s. The 30-06 has successfully killed pretty much everything walking on this continent. But you get the recoil of pushing a 30 cal.
If she's already got a 270Win I wouldn't consider anything that class or smaller. She's already got a great hunting round in that class so there is no point in duplicating the performance from something else.
I don't have any experience with magnums other than my 7mmRM and we've pretty much ruled out the belted magnum class.
Another thing to think about when it comes to flinching is whether it is enhanced by muzzle blast using a break. Using something like a 284 or a 7-08 may minimize that.
