cjp45, I use 24.8 grn's of VV-N133, 50 grn V-MAX, Fed 205Match Primers and Lupa Brass. The velocity for this load is 3150 FPS. My 223 loves this load. My best three shot group is .107 at 100 yards. It's not a hot load, but it is very very accurate and is what I use when shooting varmints. My 223 consists of the following, Remington action trued, blueprinted to a 25" Shilen SS match barrel, 1.250 at the muzzle, Peller bedded into a H&S varmint stock and trigger job, topped with 4.5x14x50 30mm tube Leupold M1 Long Range Target. This is my 200 to 300 yard varmint rig. Try this load, I think you will like it. Let me know if it works. My friend used it in his 223, and he has seen similar results.
Good Luck, Wildcat
