Hey guys. My Remington 700 Sendero .338 win mag long range precision rifle build I'd coming along slowly but surely. I have decided I am going to rebarrel as now is the time instead of later. I called and spoke personally with Mr. Lilja of Lilja barrels Friday and with a customer service rep at shilen. What about kreiger or obermeyer? I was actually looking for a 5R or 3 groove type rifling instead of the conventional 6 groove in .338 caliber if possible with a finished barrel length of 27"-29" possibly even 30". Muzzle will be threaded for muzzle brake. Would like to keep the barrel fluted as came from the factory. Stainless vs. standard chrome moly not sure of yet. Guys any and all help will be GREATLY appreciated as this is something I don't mind paying top dollar for but only want to do it once! Thanks guys.
