    If you don't want to tool up to load for another round, then don't.

    The x54r is so cheap to feed I would just shoot bought ammo. It's cheap enough to not have to handload.

    Problem solved

    Monetize it and let it be someone else’s problem - problem solved.

    I saw that. Seen a few actually. Kinda takes the fun out of it though.

    It’s not a problem if you find it fun. And I do. Found a place. They have the action now. McGown has it for a new barrel. I am going to be sticking with 762x54r. I can actually make it 45-70!pretty easily. But I just don’t shoot 45-70 as much anymore. Going to have some fun with 762 with an nice sporter.

    If you can, find a copy of Shotgun News Gunsmithing Projects Book which has Reid Coffield's step by step conversion of a Mosin (spanning several columns in the regular magazine) to a nice looking sporter rifle.

    Here is a Cast Boolits forum posting about it.

    All of my Mosins and Mosin-derivatives are fun - and I have five of them.

    The Finn M39 heavy barrel is a good starting point for a custom hog gun. Finns make good parts.

    Thinking of so many ways to customize a Mosin, there's a guy up in I think Newfoundland... he's a youtuber... he took a M44... polished all the steel nice and bright, shortened the front end of the stock and slicked up the wood. He stayed with the original lines, but made it lighter, handier, and prettier.

    How about .30-30? Not a powerhouse, I know. But the Mosin receiver would be more than strong enough. Might make a nice little hunting rig.

    Two thoughts. There is a steel ram cartridge, they made it the "rimmed Remington." You use .303 Brit brass/shell holder and .35 Remington dies. I think the .303 rim and the 7.62x54R are close. #2). The .405 WCF was an almost straight, minimum taper, .30/40 Krag case (or .303 Brit), slightly longer, in .40 cal. There was a .35 WCF, same case necked to .358, that went nowhere fast. These are bigger, heavier bullet rounds. Another thought, Mr. Bellm, bellmtcs.com, did a rimmed line for the T/C rifles. .444 Marlin cases and shell holder and .308 family dies. .358 WCF is no problem and load data abounds. I would be conservative with that action, but you are "in the weeds." And now there is rimmed .308 brass, eg. .307/.356... Enjoy. Luck. Happy Trails.

    So here is Where I stand. I have ordered a cheap discounted Boyd’s gun stock. It’s there prairie hunter that some was selling on eBay for cheap. A timiny trigger I’m going to pick out and order some express sights from New England gun works and have some fun. Chamber is going to stay 762x54. I’ve ordered some reloading dies too. Going to learn a new cartridge.

    Interesting list of options. Considering you're talking about a hog hunter, what barrel length do you have in mind?

    Going to trim it down to 24 inch. That seems to be a good length for both long distance shots and stalking. Anymore then that won’t provide much gain and less seems to just mostly makes more noise and fire balls.

    See Joshua Smith's Mosin Trigger discussion in gunsmithing. Might be an option that you would like to use to improve the trigger.

    That 24" barrel sounds good with the rest of the picture.

    But, as a necked down version of the Imperial Russian "Three Line Cartridge, model of 1891" , would it not have to be necked to .277" rather than 7 mm ? o_O

    For an iron sight rig, the Hornady 174RN and IMR 4064 are your friend...unless you are getting a .308 bore, then the whole world of .308 bullets is open to you. This bullet works well on the feed ramp and hammers deer sized game. You don't need to fiddle with COL, just seat to the cannelure. It's been very accurate for me across a few different Mosins with little experimentation required.

    Well the Boyd’s showed up. It’s going to need some inletting for this action. I heard back on my other action and they are 6 months out on a new barrel. So I’m going to start with this one and when the new one shows up just get another stock or fit it this one. The Timney trigger feels better. In these pics you can see that the lower needs quite a bit of fitting and the upper needs just a bit. I have not cut the barrel yet. Between work, going back to college, and being a busy uncle I’ve not touched this in three weeks. I will say that the length of the barrel is not to bad. May cut it just behind the front sight since I have new front and rear traditional sights on order. I figure I can practice silver soldering on this one as the barrel rifling is truely trashed and prints about 1 foot or more at 100 yards. It’s not a smooth bore yet lol. But what rounds I have recovered have little groove marks compared to my other Mosins. For the action getting a new barrel it will the nice New England Custom Gunsworks sights.

    I didn’t want the sling studs or butt pad. This was an eBay buy. Turns out even after calling them I can’t get it with out them.

    So it took six hours and a tube of lip stick to fit. But the rifle is fitted and feeding as well as a mosin ever has. The top fitted pretty much just fine right out of the box. The bottom didn’t fit at all. The front back didn’t fit a single bit. Furthermore the front lug screw holt is drill at the wrong angle so the screw would not mount. So I had to widen the entire cut out for the lower trigger guard/mag. Depthsr was spot on. Neither the upper or lower needed any depth work. That took the longest to sort out. I do have pillars for puller bedding. And a glass bedding kit. That will happen later. Right now the rifle looks like a rifle again and shoots. The front of the stock around for end looks like crap as far as fitting goes. Way to much of a gap. But I’m kinda stuck with it.

    > So, is the Mosin action strong enough for 35 Whelen?

    No problemo. The Mosin action might well exceed the Arisaka for strength. And the .35 should be an easy conversion; a century ago Bannerman did a bunch of conversions to .30-06 with minimal work and no problems with feeding from the magazine.

    The Bannerman conversions had a bad reputation because they Bubba'd the job, running an '06 reamer up the Mosin barrel. Unfortunately the shoulder on the '06 is larger in diameter and farther forward than the 54R, and there was seldom more than .050" of barrel wall there. Sometimes less. Sometimes a lot less, with ugly results. No problem when you're using a new barrel, of course.

    If you want more cowbell, Tony Rumore at Tromix built a Mosin in .500 S&W. You could contact him through his web site and see if he put up build pictures anywhere; he often details builds on various forums.

    Huh. Never thought of 500s&w. I would love to see the bolt head of the 30-06 mosin to compare it to stock and see what all needs done.
