jrkrk I have a couple of disk rifles. I also had a encore that I got the first year they came out.
I did not have good luck with the encore and sold it before I did something stupid like wrap it around a tree out of frustration. The guy I sold it too sent it back to the factory once replaced a couple of factory parts and now it shoots good for him and is easy to clean.
Both the disk rifles I have shot good for me from the first range session.
The disk magnum I have with 26 inch barrel and thumbhole shoots pretty good with three pyro pellets and a 250 gr xtp in a knight high pressure sabot. However, it will sling a flyer every now and then with the 150 pellet charge. With 100 grains of 777 ffg and the 250xtp it will print snuff can groups consistantly as long as I do my part at 100 yds. However, I have had some good days at the range and cloverleafed some groups under an inch. I havent had any flyer problems yet. Dead on at 100 yds it hits about 3 inches low at 150 with the same dead on hold.
The standard disk rifle I have also shoots good with 100gr of 777 ffg and the 250 xtp. Again around snuff can groups consistantly at 100 yds and sometimes better.
I could never justify the conversion to the new type disks(the red ones) that was offered by knight because the orange disks have served me so well.
The encore is much easier to clean. It feels good to me too. I might even buy it back if the opportunity ever arises. However, I really like the feel of the disk rifles too. The disk rifles are a little more time consuming to clean if you do it right.
I feel 275 is a good price for a new stainless disk in the box. I wouldnt sell either of my used disk rifles for 275 and they are both black on black.
