I picked up a older M7 in .308 with 18.5" barrel a few weeks ago. Thinking I want to load this for my son who is shooting rimfire now. Thinking this may have too much recoil/muzzle flash in standard loads was wondering if anyone has reduced loads for a short barrel for one to learn to shoot? BTW my son is 10 years old...

BTW...guys I was thinking of getting the Ruger American in .243 per Jim in Idaho's post on him buying an American. But I just have not yet gotten over the looks of the American. I am used to rifles in the traditional sense like wood stock and blued...like what you see in the Winchesters and Remington and Rugers. Cannot get over the newer rifles with thosechanges made to the looks. So this is why I bought this M7...maybe I goofed and have to go get a Ruger American down the road.
