RE: Remington Genesis
I have one also. I got the blue/black model on sale from Cabela's. I wasn't looking for an in-line, but with the MFR's rebate it cost me $100, so figured I couldn't lose.
I like the gun a lot. I do not care for the ramrod. The design prevents a rod of a useable length from being stored under the barrel, so they employed an extendable rod that seems very likely to bend or break. The rod isn't really long enough to easily clean the gun even when extended. Most use a cleaning rod anyway.
Mine really likes Hornady FPBs with 100 gr Pyrodex RS.
