A good load I've been using is CCI small rifle primer, 23.5 grains of IMR 3031 powder and 55 grain SPBT bullets. They have performed very well and give me 1" groups at 100 yards. My load is from Lee reloading manual #2. There are a number of excellent references from powder manufacturers that can be found on line free. Each gun likes different loads so you'll have to experiment some. Good Luck and great shooting!since .223 ammo is non existant around here I`m curious as to whats a good starting point? I can get brass from the AR guys at the range.
