Fx-Impacted!

Ok tried these things this afternoon, pushed pellets through bore from brass breech to end of muzzle “Clean barrel” pellets look great no deformities (Within reason) no lead chamfered off land depressions on pellet or skirt, transfer port is free of burrs inspected with barrel out, also passed the q-tip lint test! I really think it’s a overly tight choke? That’s where the lead is concentrated! I believe the diffuser ports at end of shroud are directing the lead dust and vapor back through shroud and depositing it on the barrel sleeve just like it’s supposed to, like Michael referred to in his earlier post, (otherwise the shroud wouldn’t do anything!) I just couldn’t see those elongated ports until I really looked for them! Now onto accuracy issues? That will come after the holidays, Thanks to all your input guy’s Saved me tons of time and gained much knowledge of this rifle! One last comment “I now know how to index the moderater so Donny fl is in right position to read it!” It wasn’t from factory... 

What do you think? Clean barrel 56 shots later, no shroud or DonnyFL! Accuracy was slowly getting worse as I shot, it is trying to group but flyers all over the place! I really don’t think it’s a clipping issue don’t see any leading inside shroud diffuser ports or DonnyFL?

Not accurate at all! That’s the problem... trying to determine if it’s clipping or excessive choke or ??? But I’ve never seen a barrel look like this after 60rnds! It’s leaded alright!!!

Here’s a comparison of my LW-poly from my Daystate RW .22hp, mind you this is 60 shots with 25gr jsb’s at 950fps, just to be clear I shot two groups of 3-cleaning pellets after shooting, you will notice the transfer port isn’t as cleanly machined as the FX and also some leading at the entrance to the lands of barrel
