I have a #2 rolling block in 32RF and I was hoping to have it bored to 38/55 and swap the extractor. I got it at an auction thinking it was a larger action than it turned out to be (they were unsure of caliber and action). From reading up it looks like the #2 action can chamber the 38/55 but the strength might not be there for heavy 38/55 loads, I'd be in the bp pressure 38/55's.
Will this work or best to chamber it for 32-20/line to 25-20 and leave it OR just kick it down the road. If it was a 32-20 / 25-20 I'd probably just it a handful of times and kick it down the road.
