Could a 13 year old kid handle the recoil of a .300 win mag using full power 150 grain loads ? What about Remington Managed recoil loads ? This will be a shooting around/range rifle ( sometimes a coyote gun, not hunting for fur ) for him. For target shooting, would a Lead Sled work ? I plan to handload in the future or near purchase. I have some data off the net from some people who looked in manauals, they are light loads of course ! I forgot, the rifle ( in the title ) is a savage 111 TH XP, would I need to buy an aftermarket recoil pad or does it come with a good one ?
