Pienoiskivääri m/91 Finnish .22 Mosin Trainer (Ad-free)

This and all the other Finnish Mosins are detailed in my new book "Forged in Snow": https://www.kickstarter.com/projects/headstamp/forged-in-snow?ref=b8ft1r In the 1920s the Finnish Defense Forces wanted a reduced-power training rifle to allow low-cost marksmanship practice and to allow shooting on small ranges. After investigating drop-in rimfire conversions, they decided to make dedicated .22 rimfire m/91 Mosins. A contract was given to the ATV-1 armory to make 1,500 barrels using the Salerno process; inserting .22 caliber liners into drilled-out m/91 barrels. These barrel were paired with a rimfire conversion of the bolt, and the result was the m/91 pienoiskivääri ("miniature rifle"). Production ended in 1927 because of a scandal over the serviceability of Salerno process 7.62x54R rifles, and a second contract was given to Tikkakoski in 1929 for an addition .22 rimfire barrels. In total, about 2,500 of these rifles were made by the early 1930s. They were typically issued in batches of 3-5 per regiment, and used regularly until World War Two. In addition, a .22 rimfire version of the m/27 rifle was also produced, although not in sufficient quantities to replace the m/91 in this role. During the Winter War Finland captured a huge amount of Soviet 7.62x54R ammunition, and also developed its own reduced-power loading. This made the .22 rimfire training rifles unnecessary, and they were sold off as surplus shortly after the end of the Continuation War. Most went to Defense Forces personnel and to film and theater companies to use as props. They were never sold in bulk to importers like InterArms, and so they are very scarce in the Unites States today.

I wonder why they went with a barrel so long. 22lr seems hardly have enough powder not to be breaked down with such barrel length. -- hmm. DID anybody rebuild mosins to 7,62x39? not a strong reason why one should, 7,62x54R isn't exactly expensive, but... could be fun. that 22, too. brit no9 would outshoot that SO bad though.

Some rifles in .22LR had very long barrels. The Swedes made one (CG-63) with a 74 cm (30 inches) barrel. When .22 Short rounds were used the firing was nearly inaudible as the powder was completely burned up inside the barrel before the bullet exited the muzzle. This was like firing a silenced rifle but without using a silencer.
