I found out the .308 version only comes with a 20" barrel. I want to be able to shoot ELR so velocity concerns me, I purposely chose .308 over the 6.5 because I'm actually fine with worse ballistics so I can learn to counter them. Also I don't have reloading equipment yet so I want cheapish ammo and a longer barrel life is another huge plus. My question is if the barrel being 20" will impede my desires to shoot to 1000+ yards, and if I should not get the RPR and go for something with a 24"+ barrel length to get the most out of the .308? My budget for a rifle is $1,500.
