Re: Model 70 Extraction Problems
I have checked the extracted cases. The only "marks" are extremely light and right above the base of the cartridge. These marks look like the case was expanded against the sides of the chamber & pulled out HARD, but there are no deep marks, gouges or indentations — only rub marks. It doesn't seem like there is a rough chamber, it acts like I'm WAY over-pressure with factory ammunition. Being WAY over-pressure with factory ammunition is what concerns me.
My thought at this stage is to polish the chamber with rubbing compound, a swab, and a drill on low speed. If that doesn't work it looks like time for professional help.
