I thought about bumping up loads for my 10yo this year...but I stayed with 36gr of h4895 out of his model 7 708 youth. My 7yo maybe able to shoot it this year so I didn't want to get crazy. I've never chronographed it but your data gives me a better idea. For fun, I shot my "adult" loads out of that little model 7 youth, had a nice little punch. I know the doe my son shot last year with those youth loads at 85 yards put quite the hole in a big doe. We are using 120bt.
