The rifle in a past life was used as a NSSA match rifle & is very accurate but the sights are regulated for 65 grains of 2F with the 500 gr minie. That's what I used. I felt it was light but knew the area well & knew the shot would be close (archery range) & decided that precise shot placement would carry the day, & it did. I don't think he ran 40 or 50 yards.
