2.7 grs. or 2.8 grs. of Bullseye may be often recommended, but may not be best for every gun and may not even be a good compromise load for several. I'd load up enough rounds to fire groups in all my guns and start at 2.5 grs. As an example, in my 52, 2.5 grs. is noticeably more accurate than heavier charges, but this will often vary from gun to gun. It's worth the time and effort to find the most accurate load.
