I have had good luck with IMR 4831 in my 7mm Rem Mag (Remington 700 BDL Custom Shop Rifle) and use Win 748 in all of my .223's with consistent performance (7 different rifles...from a Rock River AR-15 to my daughters H&R single shot)...but as many have said, the bullet, rifle, barrel...and many other factors come into play. Doing your homework and taking your time are the most important.
