The Turtle Gun
« on: April 29, 2014, 09:13:27 am »



   Of many dozens of custom rifles and handguns I have built, this is the only one I have left.. Probably because I built it for my wife.
   In the Maine woods those boys like heavy calibers and light guns. The trend when I was running my gun shop was for them to buy the 444 Marlin lever action rifles, then have me modify them. Never fired befor they were handed to me. I shortened the barrels and installed muzzle breaks. Rather than fine tuning the triggers for a lighter pull, they wanted the triggers STIFF but crisp.. 
   I bought large ring surplus mousers (8mm) for about 80 dollars each, and cleaned them up and resold them.. Sometimes I used the actions to build a customer a specific gun.. I have a lot of pictures but no scanner..  Give me time.
   So I had an idea for these guys wanting big calibers..  I designed a crartridge based off of a .300 win mag case. I liked the cases because they have a shoulder to headspace on, instead of a rim or the shoulder.
   Two of the cartridges laying beside an unmodified .300 win mag case.



   I spent considerable time making the cartridge specifically for the large ring mouser actions, and sent the design to Clymer manufacturing. They in turn built me a chamber reamer, and designated it the "Sievers .44"
    I ordered five barrel blanks from Blackstar, and set about turning them down on the lathe and cutting the chambers. Threading them for the large ring mousers and head spacing them.
   I made bolt handels, put Timney triggers in them and custom safeties. Two of them I remanufactured to accept remington clips, the rest I used the original floorplates and made a button to remove the floorplate as this gun has. Trigger guards were modified etc, etc..   The two custom rifles with remington clips recieved Custom walnut stocks, two recieved laminated stocks of black, brown and green laminates, the last used the original mauser stock. I mounted sights, and drilled and tapped them for scope mounts, then ran them all through the bluing tanks..   I advertised them, and sold them with the dies needed to create the cases.
   I sold all of them but the one I was keeping in less than a week.  The last one had my wifes name stamped into the reciver, so I presented it to her for her birthday...
   She took a nice doe with it that fall, and used it for several years..  the looks of disbelief on the "guys" faces when she pulls that cannon out of the case are ALWAYS priceless.  At that time she weighed about 140 and stood about 5'6" so it was a lot of gun for her, but she loved it.. she is getting rounder now and handles it a little better with a little weight to put behind the metal buttplate.
   So the Turtle gun got its name, because my son and some of his friends were out in our front yard with their .22's plinking at snapping turtles in our pond..  they were not having much luck hitting them...  I stepped out the other door and waited, the turtle gun in hand...  A big snapper poked his head up, and the rest is history... they all came out of their chairs when that gun went off, and the turtle.. well, he was in multiple pieces....   The gun is widely known in this area as the turtle gun, and it is often heard if someone is having trouble with deer, coyoters etc. to hire the turtle gun, it fixes most problems...

   The cartridges are loaded with .300 gran soft point pistol bullets. They have the weight to penetrate, but are too soft to go clear through. they go in eight to ten inches and disintegrate. The bear that were shot with this cartridge dropped on the spot, without taking a single step, needless to say the deer do not go far either. Coy dogs and coyotes are a little difficult to pick up to load in the truck.
   The turtle gun has an OLD Weaver 4X metal post reticle style scope. It holds up to the recoil well, but you really dont want to get too close to it or it will idiot kick you hard enough to need stitches. The stock is oil finished and has seen a lot of abuse busting brush up in the northeast. It was made to hunt with, and has served well, I hope it continues to serve for a LONG time after its maker has gone.













   So lets see some pics of your favorite!

Nice!
I am a die hard .444 nut. I believe it to be the most versatile caliber on earth. I can load a round ball at 500fps for small game, three round balls at 1500fps, a light 200gr cast bullet for plinking at 1000fps, even a load that mirrors a .410 shot shell. I've used black powder as well. When I need the hammer-of-thor, a 350gr WFN at 2200fps will topple just about anything.

What velocities were you able to develop with the Turtle Gun? I am currently trying to decide on a mauser based project to undertake. I was actually leaning toward a big bore since I am also a cast boolit fan, either 405 (.411) or 44 (.429), using one of the belted cases.

Max loads were running about 2630 FPS through the Crono and still producing 2" groups at 100 yards. I pushed 180 grain hollow points to just over 3200 and hand cast 365 grain bullets for planking targets at 1000 yards at around 2480..
  (Off the top of my head. Dont have the journal in front of me.)
   Loading the hand cast 240 grain bullets with copper gas checks down to around 1000 fps makes it a real joy to shoot, but the best accuracy at 100 yards is with the 300 grain at around 2500 fps. From sand bags it will destroy a soda can (unopened) every shot, and really ticks off some of the 22-250 varmint guys that live here abouts.
   I think if I fussed a bit with the tin/antimony in the cast bullets I could probably get better accuracy at lower velocities. I have never tried loading black powder for it. I dislike the scrubbing involved after a day of shooting.

   It is about all the gun I want to shoot if I intend to shoot it more than three or four times. I owned a .458 weatherby, and it was an excellent gun that shot very well, but after the third or fourth shot I had no desire to pull the trigger again.
   A good friend had a 45-70 Bolt gun that I liked about as much as the turtle gun..   We used to use a single thumb tack in the center of the paper plate / target with a black dot magic markered in the center..   That 45-70 would make the plate fall off the backboard three out of four shots.

   I built a small ring Mauser to accept a .44 mag by shortening the action and building a custom stock for it. I have built quite a few custom rifles in a plethora of calibers, but like you, I like the big bores.

I had a 458 win. mag. that I was so happy to trade for an over under 12 ga.The 458 you felt in the heel of your feet after you shot it.Mostly I use a Browning A-bolt 300 win mag. 
I don't know.It was like that when I got here.

.300 win mag is enough gun to take down anything in the world that walks.  the .30 cal bullets are available in great diversity, so if you hand load you can tailor the .300 to just about any task.  I used to shoot accelerators, which were just sabbots with 75 grain hollow points all the way up to 225 grain BTHP Hornadys. Accuracy suffers one way or the other depending on the twist of the rifling in the barrel, but tinkering with speeds/powders etc was about half the fun, trying to get the best accuracy with each load/bullet weight.
   458 is an impressive round, unfortunately that impressiveness is impressed upon you every time you pull the trigger. I like to shoot for fun, that .300 is right there on the borderline for me.
  the versatility of that caliber prompted me to build a mountain gun from a .300...   short light barrel I tapered and chambered myself on a large ring mauser with a lightweight birch stock... with a 165 grain bullet it shot sub MOA in a gun that weighed in at just over 5 pounds...  It was a little bit brutal to shoot, but it was easy to carry...   Then one day that emergency shot arrived, the gun came up, cross hairs centered....  split my eyebrow open when the scope hit.. 5 stitches later I sold it...   Always regretted selling it.. moving the scope forward an inch would have fixed it.

The 300 short mags are popular out here.If I was buying another rifle that's probably what I'd get, but I always go back to old faithful.
