I have a .45 caliber CVA Firebolt Ultramag (nickel plated barrel with synthetic stock).  Thanks to FrontierGander's recommendation in a previous post, I changed to a Kodiak/Optima breech plug (AC1678a) and added an o-ring to be able to shoot BH209 powder.  The gun now shoots BH209 without any problems.

I would now like to improve the accuracy.  The group size varies, but sometimes is around 3 inches at 100 yards.  I would like to improve that.  The scope rings are snug.  I am currently shooting a 200 gr. SST bullet in front of 90 gr. BH209.  The barrel presently fits tight in the forearm of the stock, resting on a series of "ribs" or "cradles". Could this tight fit possibly be affecting the accuracy?  If so, is it possible to free float the barrel?  How would I go about doing this?

Rick, remove that plastic from the stock channel thats rubbing against the sides and under the barrel. I normally used a few pop can shims under the lug to lift the barrel up and then everything was good to go.

Here's one that shows how to do this, Marty also has his pictures to help out as well.

i used the section of a  wood handle from an old broom and wrapped some 80 grit around it to clean out the barrel channel.  it only took a few minutes. i have not got around to the jb weld yet, it seems to shoot ok as is.
