I need a refresher course in M39 mosin Nagants.

[krinko]

The Finns did extensive work on improving the basic Mosin.

1.Adopted a shorter barreled rifle in 1927.
2.Also, starting in 1927, rehung the trigger to get cleaner trigger pull. Some of these have a coil spring added, as well.
3.Used a variation of the Swiss M1911 aluminum barrel bushing in the forestock bearing surface of the M28/30.
4.Refined the back sight starting with the 28/30, adding a windage adjustable front sight in the process.
5.Dropped the aluminum barrel bushing for the M39, just like the Swiss did for the K31. This would seem to be a deliberate effort to get the maximum accuracy out of a full stocked military rifle.
6.Etc.

As for this:" Does not make a whole lot of sense to shoot these rifles off a rest."
I don't know what that means.
With my M39, firing from a rest and using a spotter to walk me in, I hit a 12oz. 7up can on the 300 yard rail at my club range. Shot number four.

These rifles, particularly M-39s can be shot incredibly fast from the standing position without losing the weld to your shoulder. Does not make a whole lot of sense to shoot these rifles off a rest.

I'll take a bit of exception to those claims. first of all, maintaining cheekweld is pointless if you're losing sight picture, which is impossible NOT to do if you're firing a rifle with a straight bolt handle. incredibly fast is subjective to the amount of practice a shooter has had. the only bolt rifle I've every considered "incredibly fast" is a enfield which is far easier to shoot fast than mosin nagants. secondly, nobody intentionally makes a rifle harder to operate, military engineering makes it a point to improve where possible to increase efficiency and effectiveness. intentionally leaving a crude design as is because "it's designed be hard to use" is about the same logic as saying "a tank is SUPPOSED to only have an effective operating distance of 100 miles". lastly, anyone who claims there is no sense or purpose of shooting these rifles from a rest needs to learn about a fellow named Simo Hayha

Amazing that after all of these detailed responses, nobody thought to recommend to the OP to slug his barrel. The only tried and true reliable way to select correct diameter bullets for any milsurp C&R gun.

question, has anyone tried the rock solid zipper strips on a M39? they look pretty nifty.
