I would appreciate all the senior shooters (50yrs plus) in competitions feed back on this matter... Lets say you have two guns to choose from.. 1. 6mm moving 105gr at 3,100fps, light recoiling... 2. 6.5mm moving 140gr at 3,000 fps, heavier recoiling... If you play the numbers over at Applied Ballistics you will see the greater hit percentage given to the 6.5mm.. So the question is given the slight improvement in hit percentage in all conditions which one would you still choose knowing you could have that advantage over the 6mm... How much does light recoiling aid you in hitting the target??? In this circumstance shooting will be from multiple positions.... Thank You
