flint head
I bought a pack of these to try in my new Knight Disc Elite in the 250 grain Red Hots ( Barnes Expander MZ ). With a load of 3 777 pelletsI was getting terrible results about 2 1/2 inch groups at 100 yards and I know this gun is better than that...
Reading down through some of these post - the thing that stands out for me the most is the word NEW Knight.... 2 1/2" in a 100 out of a NEW barrel really is not that bad. Get a 100 rounds thru it then judge it. Barnes are awfull good bullets and the sabots are made by MMP so I think the combination is correct - although I gotta tell ya... Noslers are better bullets - just my opinion!!!
Might try something in that Knight if I can suggest - contact Cayugad have him give you his technique for polishing a barrel with JB's bore paste. Your lands and grooves will benefit...
Just as a side note - I shoot 100/110 grains of T7-2f and get really very good accuracy.
Good luck - mike
