RE: 7mm Rem Mag Recoil
No matter how you slice it, the recoil of a 7mm Rem Mag is going to be more noticable than a 270 Win. Especially if your 270 Win is a semi. Just how much more the 7mm will recoil depends on the weight of the rifle, the weight of the bullet, and the powder charge. I have had a 7mm Rem Mag and now shoot a 300 Win Mag. I feel the 7mm's recoil is sharper and more unpleasant than the 300 Mag, but not altogether unmanageable. I actually have little use for a 7mm, but that is just my opinion. I find the 300 Win Mag to be more versatile.
