I want to buy may be my last long range hunting rifle and i need informations to choose who will build it for me, the caliber and a lot of things, for now my only choice is the Mc millan stock (Lazzeroni sporter). For the caliber I want a really fast 30 one, 300 hulk may be... I would like a caliber that use nice brass quality may be a standard caliber all I want is, First high precision and second really high velocity, I'm reloader but I don't want to have to turning neck of my brass. I don't know what's the best fit between the brass and the chamber for my utility vs accuracy, i can buy some reamers for this project, one for the chamber and the other for die, I don't know, I want to be sure of the result. If these rifle would be accurate .375 MOA or less it would be fine. Who would be the best for me for this project, i have to choose barrel lenght, etc.. I want a rifle weight approx 8.5 pounds. Let me hear your comments about that Thank You.
