Took the Knight Disc to the range today to see if I could tell what bullet weight it likes. Pretty breezy conditions today with a 14 mph wind & gusts to 23 mph, so I shot at 50 yards.
Shot 2 groups with 110 grains ffg T-7.
First with 300 grain Hornady XTPs:
Next group with 240 grain Hornady XTPs:
Looks like it likes lighter bullets, so I decided to change powder. Used 110 grains Pyrodex R/S ffg for a group.
Looks like it doesn't really matter which powder I feed it, but it is going to be picky about bullet weight. Never shot a deer with a 240 grain XTP (I have killed one with a 300 grain XTP), but I may give it a try this year.
