1 mile it depend's what bullet I'm using, 225g ELDM says I need 21.1 Mils (73.8 moa )of elevation, a 230G ATip 18.6 Mils. (65 moa)To convert mils to Moa multiply by 3.5 or divide by 3.5 find Moa. Hope this helps.
I own both 300prc and 338 lm and to be honest, I do enjoy shooting my 300prc alot more vs the 338. Just a great round for the money in my humble opinion.
