The 308 class of guns 308, 7-08, 6.5 creed kill well and are more user friendly than the 30-06 and up in similar guns. When my son and I go to shoot we stay 4 to 5 hrs and take multiple guns from .22 on up. My braked 308 ,6.5 Rem mag, 30-30, 7-30 Waters, 35 Rem.and such I can shoot all day without undue pain. Not so with the 30-06,.358 J.D.J.,45-70,etc. They are more 3 to 5 shots and lay them down for awhile, or bad habits sneak in that are DAMN hard to get rid of. Everyone has different recoil tolerances and I know mine. If a softer recoiling gun will do what I want that is what I will use. Why do I keep the boomers? I'm dumber than a rock,like variety, and still love them, but in smaller doses.
