I consider myself a proficient marksman, having been trained with PB's, and I believe the basics are similar to shooting a big bore PCP. A few weeks back, I attempted to hit a 10-inch gong at 500 yards with a PCP, but I only reached 400 yards and was hitting just the outer edges of a sight-in paper target. During that season, the open field is quite windy, but I plan to try again this summer when the air is less dense and free of gusty winds.
