RE: 6" - 7" Spread - What I'm I doing wrong?
 

The .45 caliber Knight Wolverine 209 with the 26" barrel has a 1-30 twist. And yes there were shorter models that first came out with a 22" barrel. The manual will tell you the maximum charge but since yours is a 209 ignition I will guess to say that the max charge would be 150 grains of powder (again, refer to your rifle manufacturers recommendations). That does not mean you will get the best accuracy with that kind of load. For instance the Wolverine II which I own has a 22" barrel and they recommend 120 grains as a max load. I personally think the rifle could handle a larger charge but because of the short barrel would never get the chance to burn that off. My rifle depending on the powder and projectile tunes in between 85 - 110 grains of powder.

cayugad how low have you actually loaded and had good accuracy. i just always loaded 80 or 90 grains for practice being the same as i hunt with. ever been down around 30 or 40 grains. just wondered how it worked out.

RE: 6" - 7" Spread - What I'm I doing wrong?
 

I loaded down to 50 grains of Goex 2f and a REAL conical. And that rifle was just drilling the bullseye with that light load. With roundball I had the rifle down to 40 grains. I was getting an occasional flyer but accuracy was very good at the 35 yard station. The recoil was not even there at that point. That was a day when the kids wanted to shoot, so we were loading everything light for them so they could blast away and not be scared.
