I have a Knight Master Hunter Disk Extreme that has been in the possession of the gunsmith more than it has been in mine since I bought it 11 years ago. It has failed me on 3 straight hunts in a row, so I decided to get something else and the rifle is going back to Knight to see if they can figure out the issue once and for all. When it shoots, it is a very accurate rifle. Anyway, living in New Mexico, I am planning on using this for the deer hunt and hopefully for an elk hunt at some point. Thank you for the advice! I will start with the load you recommended and work from there.
I was working at Academy Sports in 2007 when we got the Knight disc rifles in and I said to myself, then, that there would be problems with that rifle. We sold three of those, and all three were brought back by the customers. We replaced them with one of the break over models that Knight had, and it performed very well. I've had mine since 2008 and never had any issues.
Knight has developed a new disc bolt that is supposed to be the remedy for their earlier problems.
I just upgraded to the new Knight VISION MAX 1 BREAK ACTION, which is a break-over rifle. We put 10 rounds thru it last weekend and it was almost perfection at 100 and 200 yards! Also shot my old, first muzzy - CVA Buckhorn. It's still a tack driver too! Shot my first 6x6 bull elk with it in November, 2001 at a range of 154 yards!
