Aquatech,my Omega was a bear to load untill I lapped it [I fire lapped mine] it loads much better now they have cut barrels and some times fine burrs and sharp edges on the rifleing.There are a number of ways to lap for this purpose I rub polishing compound into ticking patches and shoot round balls till the bore is polished. I have heared of people mixing it with grease and shooting lead bullets. You can also pour a slug right in the barrel and drive it out and put compound on it and push it through the barrel till it is polished, for this process you should hunt up some experanced help. Good Luck Lee
