As stated above they are about the same but I would choose the 6.5 for one reason only.
Reload with lighter bullets like a 100 gr NBT and down load it to around 25-2700 FPS and it should be a pussy cat. Yep, Yep2 y’all. A 100gr Hornady at 2500 to 2600 does more than you might think. That’s the speed a lot of folks are getting out of 5.56 ARs with the mind numbing and magical 77gr TMK. And in a 20” Model 7 the recoil is cream puffish. At 100 yards the crosshairs don’t leave the target. In a couple years as she becomes more tolerant just ease up to full charge 100gr TTSX and shoot whatever presents itself.
