I'm having fun figuring this one out. Of my four, only the little 44 mag from the 60's has been flawless. The carbine 30-30 above it in the picture has taken a giant 8 pt. and a bigger 10 pt plus other deer. It had initial problems with fouling and bedding. That one took months of serious cleaning and polishing with both J.B. Paste and Autosol polish to smooth the barrel and stop it from fouling so it would shoot.
It now shoots great but yours... Yours will shoot great right from the start. Trust me, I'm Polish.
