FWIW I have been shooting my 6.5 PRC and 7 PRC back-to-back quite a bit the last several weeks.
6.5 PRC is a Seekins Havak element
7 PRC is a Christensen Arms Ridgeline FFT
Both rifles are shot with my Hyperion K suppressor (CA was shot with a muzzle break prior)
My thoughts:
Recoil wise, the 7 PRC is LESS then I expected and the 6.5 PRC is MORE then I expected (coming from the 6.5 creedmoor land). Neither is punishing at all (and these are in lightweight rifles), and I can blow more money on ammo shooting then is practical in a short amount of time

The 6.5 is obvious a decent bit less than the 7... but with a can, both are "pleasant" to shoot and sessions of 30-40 shots are easily done.
Stock and recoil pad make a difference... the CA 7PRC is significantly more pleasant to shoot then my un-braked T3x in 30-06, for example. The Seekins is in the same ballpark as my 6.5 creedmoor T3x.
In my opinion, at least with my rifles, recoil is just not really an issue (at least with a break or can).
Both are awesome rounds!
