I have 4 Brown pounders (Ruger 77 tang-long- 6.5 Rm, R700-3006, 2 R700's -7MSM) and have filled and finished them all myself. My finish isn't perfect but I also don't do auto paint and body for a living. I have worked fiberglass boats and done Bondo repairs before so I didn't find them so hard. The big thing is to not be in a hurry. I really like mine and would use them again in a heart beat.
