I installed a Skinner peep site on a '82 Winchester 94 30-30 for my 13 year old. At 100 yards he was grouping the shots at about 3" consistently around the bull’s-eye using factory Remington 150gr loads.
We also tried some of the Remington reduced recoil 100gr (I think) and I was very surprised how well they shot. They seemed to group on the low side of the bull’s-eye and as far off as 5" but all and all not too bad.
I guess I'm old school in thinking everyone should start off with iorn sites and move up from there. I'm not by any means on the level of most that post on this forum but it's how I was taught and we have plenty of guns with scopes that he (my son) can choose from in time.
