I am going to pick up one of those Dicks Remmy 700 on the black Friday sale for my son in .223. (with the coupons my wife has I will be able to get one for right about $300) They come with a 26 inch heavy barrel so I want to have it cut down and recrowned. Just want opinions on a good length? Somewhere from 16 to 20 inches. What do you suggest? This will be for plinking/coyote hunting. Shot out to 3-400. Maybe 600 at steal for fun. (he loves shooting my 308 at my 600 yard steel)
