I loaned the guy who bought my practice my .44mag H+R single shot to let his 7 yr old so deer hunt with this year. I loaded him some .429421 at about 1350 fps from the rifle telling him that that combo would be easier on the kid's shoulder, quieter, ant at least as effective at under 100yds as the .243 he planned to purchase for his 1st gun. This advice, as you can imagine, was not similar to advice from others. He was skeptical. He sent me a picture of his smiling 7yr old sunday night with my gun and a small doe as his 1st deer. On a follow up phone call, could hear his son in the background say "Tell Doc his gun worked good!" I smiled inside and thought "yep"!
