With the new free form 1, I'm debating finally making my 77/357 a SBR similar to (I think) @GoLoud 's one. Does anyone know how difficult it is to remove the barrel for threading? I'm up in the air between just having a new sbr barrel blank done so I can keep the factory one, or just shortening mine, getting a new dovetail cut for the front sight, and calling it good. This is pretty much what I'm thinking about doing. Figure 158gr .38 special will be subsonic out of that, but I'll still get ~99% powder burn on full house .357. It'll just be a hair longer than the stock forend instead of inset suppressor.

The hardest part about removing the barrel will be finding a way to safely hold the receiver without damaging it. It is not like most bolt actions where they are mostly a round action and action wrenches are a dime a dozen. Having a new barrel made will probably be a little more expensive than a standard bolt action. The barrel has cut outs for the extractors. So the barrel will need to be threaded, installed, torqued, then marked, removed, and the slots milled, then reassembled. I think it would be more economical to have the original barrel threaded. It can be done with the receiver still attached. Most gunsmiths that do this type of service have mandrels they have custom made to go into the actions where the bolts go, and extend past the receiver. That way they can turn it between centers. You might contact these guys and see if they would do it for you. https://www.jpgrips.com/order/p/ruger-77357-and-7744-barrel-threading Otherwise, I am very happy with my factory threaded 77/44 and 77/357. It was not hard to work up subsonic loads for both, using 180gr 357 bullets, and 300gr 44 bullets. No SBR hoops to jump through just to save a couple inches. |
