Many AR members have told me that Mosins are crude, rough, awkward and unsuitable for a sporting rifle.
(except one)
I find them just the opposite, super strong, and highly suitable for large bore cartridges. I move the bolt handle from the middle, to a location behind the bridge, and install a normal scope base on the receiver.
Here are some pictures that might interest; might not.
First two are a 1937 91-30 and a 1917 91. Note that both have the internal shoulder similar to a 98 Mauser.

This shows a 1942 and a 1954 Mosin. Note that they eliminated the internal shoulder, and on the 1954 one, broached the rifling out to form the bolt guide ways. Could make a take down out of that one!
Anyway, for your info.

No of course, someone at your level of artisanship would not use one. The lines of them do not exactly flow smoothly. They are an acquired taste, but very useful in some ways.
Pretty sure never is the appropriate word.
I'm not trying to make converts; just show the design changes.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.




What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

And that is flat out amazing. As is having one converted to 9.3x62; nothing like the original rimmed cartridge.

Here is a load development target from the original rifle in 7.62x54r demonstrating the OCW method.

While the 43.6 grn load is very accurate it is likely unstainable as .4 increase cause the grpup to open way up. But you can see steady improvement as the powder charge is increased. I settled on 46.2 splitting the 46.0 and 46.4 while maintaining sub MOA accuracy.



Here is my deer hunting load when it was in 7.62x54r I settled on 54 grains.

I see the 7.62 x 54 is still very busy in Ukraine. That would seem to make it the world's longest serving military cartridge. Wink

Would you mind posting some photos of how you moved the bolt handle? I don't have an action and am interested in how that works
Thanks

The 7.62x54R cartridge is very much alive and well in the Russian and most East block countries' armies; still used in the PKM and PKT machine guns. I even saw one Ukranian guy (Soldier, National Guard, Civilian, Foreign Volunteer; they all wear uniforms) with a 1941 Mosin PU Sniper rifle.
However, I would never build a rifle for that cartridge; there would be no challenge to it.
Yes, it is the longest serving military cartridge on earth; the 9mm and the 50 BMG are still being used here;1901 and 1920. So not far behind the 1891 Russian.

Now that really improves the looks of the Mosin. What cartridge would be a good fit for this action and be unique enough to make it interesting?

the 9x53r would make a great woods and pig rifle. 250 gr 9,3 bullet around ~2000 fps

I've made them in 762x54R, 405 Grenadier, 405 WCF, 50-110 win, 500 S&W, 45-70, 38-56, 375 Flanged Mag, 444 marlin, 9.3x62.
The 9.3x53R is popular in Finland for moose/elk.

Nice look. The bottom two appear to have modified M17/P14 trigger guards? I like the dogleg bolt handle and the FN style too. How was the magazine constructed?

I have one that dpcd converted into a single shot 45-70. Very accurate and fun to shoot. Draws a lot of attention at the range when I compete in single shot matches.

Several years ago, I built a heavy F-Class rifle for a Russian immigrant in 7.62x54R using a BAT action and 30" Krieger .308" barrel. Had a reamer made to match spec's and did load development with Lapua cases and Sierra MatchKings. Wonderfully accurate at velocities approaching a .300 Win Mag (used a chrono). Easily as accurate as any .308 Win match rifle I've made. Would also make a great hunting round in single shots that take only rimmed cartridges.

Bob; I put different mag systems in these. some are single shot, like the bottom one in the pic is a 375 Flanged Mag. Sometimes I use the original mags. Sometimes they are internal and then I use the 1917 TGs.
Unfortunately I can't build any more because an AR member has stolen my stock pattern and won't return it.
