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!
