This group was from my recently purchased para pro custom. 250gr lead 3.3 gr of clays so chugging along at a mild 710fps. I had to elevate the front sight so only 1/2 the blade was within the rear sight, held at 12:00 on the wood so the target was obscured. I fired 5 shots, you can clearly see 4 hits, there is what might be 5th but I can't explain it. It doesn't look like it penetrated the wood but the mark (lower left corner just to the right of the bullet hole) is exactly the same size as the other holes. Distance was 100 yards, arms resting a bench.
