Ruger RSM .505 Gibbs Conversion

[CTDolan]

A question to any and all – do you have a Ruger RSM which has been converted to .505 Gibbs? If so, can you send a few images of the feed rails, ramp and follower? I’m going to be doing the same later this year and was wanting to see how a few others have addressed these aspects. Based upon some preliminary work I am thinking that the rails, with two down, won’t require much work, if any. I am definitely going to need to lengthen the magazine and address the feed ramp when doing so. Further, the front receiver ring will need to be opened a bit to accept the Gibbs case. As for the follower, though, that might be able to remain stock.

Anyhow, just trying to think ahead and learn from others who have already walked the same path. Any information which can be shared would be greatly appreciated. Thank you!

BTW, going to ultimately make a new bottom plate as per Rigby’s “coffin” style, so that she’ll take three down. If any are interested in one for their RSM, in the big Gibbs, I’ll do it up, no charge.

@ActionBob has one.

Yeah, and he’s not too far from where I live. But, I don’t want to burden him (take advantage of his previously displayed generosity).

@CTDolan We should make this happen. I'll be home in a couple days and dig it out of the safe.

And I bought mine all ready done. So don't know what or how it was done. But we can compare to a 416 Rigby which is what I am told it started as... but I'm not so sure the barrel OD is not bigger. I'll have to measure. Or allow you to
