I use IMR 4350 and Win 760 with 100-105 grain bullets. Very accurate.
For a ball powder...Win 760 works really, really well. Even more accurate than 4350 in my rifle. Bullets I use are the Sierra 100gr and the Speer 105 gr. Win 760 meters in a powder measure super accurately, and so makes a good choice if you use a progressive. With that load I often get 1/2" outside diameter holes at 100m, on a rest, in my Remington 600 Mohawk carbine (really). Velocity is less than using IMR4350, but I never saw a deer that cared. When going after deer, I rarely take anything bigger. The .243 600 does the job with the least amount of weight and recoil. Truly one of my favorite rifles.
