RE: Youth load forT/C Black Diamond?
You didn't say what bullet he's using, but 90 grains T-7 and a 250 grain Speer Gold Dot in Harvester Crush Rib sabotsgives me a little over 1700fps from my gun. A fine 150 yard load and not a lot of recoil.
Or, switch to 90 grains Pyrodex for an even softer shooting load at around 1500 fps.
