I have just purchased a new Remington Sendero SF in .300 Win Mag. I am interested in turning this into a "beanfield" for my deer hunting here in the Southeast. I have already ran nearly two hundred rounds through the barrel, the first fifty with a boresnake following every shot, the next fifty with the boresnake following every third shot. My first few groups were one holers at 100 yards, and the best five shot group was 2.13 @ 300 yards, the worst 3.4. I am already very pleased with my choice of guns but would like to do everything within reason to it the most accurate rifle I can. Any tips as to what I can do for the rifle would be appreciated.
