I have a12" 7-30 waters barrel that I love plus a 221 fire ball and 30-30 .I now have an uncontrolable urge for a 12" 6.5 tcu. My question is, if I shoot 120gr bullets at 2100 fps from the 6.5 tcu and and same bullet weight and velocity from the 7-30 waters ,will the tcu have less felt recoil because of the smaller case head. I'm looking for a very light recoiling round the will kill deer and coyote out to at 100 to 150 yards and want smaller than 7mm. Thats my best excuse for a new barrel , please humor me, thanks
