I just don't get why people can't accept that a punk-ass loser killed JFK

71. No link but the testimony of 2 gun collectors in 1969.

One I worked with the other was a friend, neither knew the other. Both had bought the same type rifle because of its notoriety. Both men said that their rifles were extremely inaccurate and that they would never use them to hunt and not even to shoot again on the range as that would be a waste of ammo. Both these men were expert marksmen and not prone to lying. I trust what they told me.

But here's a link that might shed a bit of light:

The Italian government adopted the 6.5x52mm cartridge and the Mannlicher-Carcano M-91 bolt action rifle in 1891. This rifle and cartridge served the Italian military through two World Wars, victoriously in the First, and in a losing effort in the Second.

The M-91's used in WW II were, in the main, not very well made rifles; nor were they particularly accurate. Although the M-91 was always nominally a 6.5mm rifle, during the long years of production the bore and groove sizes of barrels varied considerably, which certainly did not help the rifle's reputation for accuracy. At least some (and perhaps all) M-91 TS Carbines were rifled with an unusual gain twist in their handy 21" barrel. By the end of the Second World War many of the M-91's had actions that were rather loose. In addition, the Mannlicher-Carcano action is not an easy one to adopt to a telescopic sight (although it can be done). For all of these reasons the M-91 is not the best military rifle to use as the basis of a sporter--in fact it is probably one of the worst.

The one real virtue of the M-91 is that it was a fast to operate. Perhaps this was partly because the action was not real tight, and partly due to the Mannlicher design. But for whatever reason, the bolt slid very easily and very fast in its recess. A buddy of mine owned an M-91 Carbine, and I remember it as being the fastest bolt action military rifle I ever cycled. Practically anyone, with a minimum of practice, could shoot a Mannlicher-Carcano rifle quickly.

A number of these rough rifles were brought home as "war trophies" by GI's after the conclusion of hostilities in 1945. Later on the Italian government declared the remaining M-91 service rifles surplus. A large number of them found their way to the United States, where they were sold to shooters seeking an inexpensive or knockabout rifle for deer hunting.
