I don't own an Ultra but do own a 7MM Rem. My cousin owns the ultra. His is a Remington 700 BDL Deluxe. The 7MM I own is an old Ruger 77 w/tang safety given as a gift by my Step-Dad who owned it for over 20 years and fired it 8 times. THe Ultra I guess by stock design seems to kick less than my 7 Rem. I know this isn't the case but my cousin installed and R3 recoil pad and I've now installed an R3 on my 7MM. I do agree that if you only fire factory ammo get a 7MM Rem. and not the Ultra as factory loads seem pathetic and are very limited nowadays for the Ultra. 7MM Rem. Mag ammo is available about anywhere that carries 30-06 ammo.

Note*
If you do handload as I and my cousin do the 7 Ultra can achieve some awesome velocities with a 26" factory barrel.
