their are alot of things that play into recoil other than the round being shot , the shape of the stock the weight of the gun the length of the barrel.
Is this gonna be a custom gun or the factory elver gun? If you have ever shot the 30-30 in the Marlin 336 then you can expect a little bit more recoil than that but a bit less than the 35 Rem in that gun which has a suprising amount of recoil ,not that its bad just a bit more than one would expect.
I got into a kick with the lever guns about 10 yrs agao and I know have the 30-30 35 Rem , 444 and 45-70. I have thought about wildcatting the 444 or the 45-70 by necking the case down to 30 cal and shooting the big round nose bullets , it should give velocities in the 2500-2700fps range and that would be in the class with the 30-06.
I'm surprised that you think the 35 Rem kicks. I wonder if your stock has funny wood grain or something. My 336 35 Rem and my hunting buddy's have very little recoil with 200 gr RN at 2000 fps. It might be that you are so small and skinny! LOL
The critters have to win every time, I only have to win once.
James hit it perfectly. "Felt recoil" is about perception and many different factors.
Stock material (glass flexes compared to wood), weight of the gun, type of recoil pad, size of butt, angle of butt, LOP, cheekpiece and angle to the face, individual familiarity with recoil and ability to handle etc.
Some guys cannot handle a 308 with everything in their favor and others consider the 308 like a 22.
Only way to know for sure IF you are recoil sensitive is to try it.
