I got the bug to build another gun. Want something small for low recoil and fast. I don’t mind wildcat rounds but am thinking I want to keep this one simple and have factory ammo at least an option. 204 sounds about right. I have a Remington 700 action I will blueprint, a Masterpiece Arms chassis, Leupold scope, but no barrel yet. Did some quick looking and it appears a .20 caliber barrel is going to be a little more difficult to find than others. I don’t want to wait 6 months or more to have a barrel made. Where can I find a good .20 cal barrel in stock? Hart’s website is claiming a 8-10 week wait. Wonder how accurate that is. I’m also considering having the barrel fluted just for looks but don’t want to sacrifice accuracy. If the barrel is heavy enough will fluting change accuracy much? I am wanting this gun to be as accurate as I can make it out to 300yds. I have other guns if I want to shoot further than that. Thanks
