I've had a couple, and gave them away to those in need...

I was perfectly happy with performance with stout loads and 150 grain Speer FNs..

For heavy duty, I actually loaded it with 220 grain RNs and W 748, with the bullets seated deep and powder compressed...

but for general use for kids...18 to 20 grains of SR 4759 and the 150 FN Speer, or 110 gr RNs/or SP with 10 grains of Unique...

more than capable to 150 yds...
