I own a Knight Super 45 DISC. The gun is supposed to be accurate to 200 yards and shoot 150 grains of powder. When shooting 150 grains the bullets tumble, i thought no big deal and decided to back it down to 100 grains. At 100 yards it will shoot 2 bullets in a nice group but it always will throw one. I cannot figure out what the problem is, i have tried different bullets, different brands of powder, even switched from pellets to loose powder. Please help!!

Have you cleand, I mean realy CLEANED, the bore? This sounds like residue build up in the lands and grooves. Also - how does the muzzle crown look? Any chips dents in the lands/groves at the crown?

Swabbing between shots may help also!

Yes, it was cleaned VERY well a few days before i shot, and i used to swab between shots but it didnt seem to help so i thought why bother.

Are you shooting Sabots? When I had my Omega I found out (by recovering my sabots from the range) that the sabots were blowing apart from the pressures (it was a tight bore) The gun would shoot 100 grains of poweder fine but when you got over 115 or 120 it was blowing the sabots apart, pedals from the side and sometime blowing out the bottom. follow this link to my solution...dont know if this is your issue but it may be worth a try http://www.muzzleloadingbullets.com/muzzleloader_magnum_sub_bases.html I used these until I sold my omega and I have not had this issue with my encore.

dont know if you can find these in 45 cal

NOt real familiar with the disc guns. What is used for ignition? We have had the same issue with 209 primers and figured it out to be certain primers did this. I changed to 25 acp in my Encore and it helped the "flyer".
