Building a 6ARC from a Ruger #1 ?

[Bassfish1952]

The extractor part of the ejection system probably will need to match the head size/rim of your 6mm ARC brass. As an example, I once re-barreled a 45-70 Remington rolling block black powder cartridge rifle to 40-70 Sharps. The 45-70 extractor would not extract the slightly smaller 40-70 cartridge. Fortunately, I was able to find a couple of extractors. The Rolling block ejection is different from the the Ruger #1 but the idea remains the same, removing spent or unfired cartriges from your rifle. The ejector/extractor needs to match the head/rim of the case.

Ruger did make a #1 in 7.62x39 but only 200 to 300 of them so they're gonna be hard to find. You might call or write to Ruger & ask them, if by chance, the might have a 7.62x39 extractor still in stock.

I took a chance and bought an older Ruger #1 7mm mag, case size is different but I'm going to see what it would take to make a 6 arc or a 6.5 CM out of it. Should be able to get a lot of barrel and still stay really short and somewhat light with that rifle.   So far I have yet to need more than 1 round per deer and it looks like it would be just as easy to load one than work a bolt.
