I bought some new winchester 223 brass when I usually use remington brass and was wondering if I should expect a different pressure and load accuracy from the winchester brass. I use 24.5gn of 2230 powder and 55gn vmax bullets . my worst group with that load is 9/16 of an inch with 5 shots at 100 yards. I wanted to know if any one had some opinions on what to expect.
