Do you ever get bored? I don't as a rule but to all rules there are exceptions. Between project pieces or just need a break, I get bored then my mind gets really obsessed with my hobby. When there is a bunch of junk laying around in corners I fantasize and imagine what I could with stuff. Most of the time I make some really stupid contraptions that are more of a waste of time than practical.
A few years ago while looking over a relic Swiss Mauser action that once was a 8mm (7.92mm) with the barrel blown off sometime back in time. A nice large ring receiver with a decent bolt and not much else. Considering that the 8mm cartridge shared the same base dimensions with many other cartridges like .308, .30-06. .22-250 Remington and ,45 acp etc. I weighed the possibilities. The .45 acp was my choice and it was off to the races (not a fast race) so I got paper and pencil, made some calculations. .45acp military ball ammo at 880fps is subsonic but great energy. To make something accurate in a shoulder held gun was the goal. So at what particular barrel length would the expanding gasses of ignition be consumed at the point of exit? Doing so would optimize the energy and limit the amount of muzzle blast (report) on firing. I had a chunk of rifled barrel stock with a .45 bore. Heavy stock that I picked up for no apparent reason somewhere cheap! Had British Birmingham proofs on it but a large OD. I didn't think it would be a very long barrel when finished. so I didn't consider reducing it's over all diameter. So I threaded it to fit the Mauser action. Chambered it for .45acp. I was beginning to be happy. Put the damned thing in a rest and started test firings and length cuttings. Pretty cool, (I thought) Now what? I had the barreled action green Parkerized added some scope mounts and some optics. put the whole thing on s custom fingerhole laminated stock. Made a few accessory adjustments and additions, Timney adjustsble trigger, spirit leve etc.
It works pretty well.Not really silenced but not noisy either (weird sound though) quite accurate out to a couple hundred yards. Kinda nuts huh???
It was fun and gets attention at the range.... laughs too! John
