Hello All,

You may remember this post from a couple years ago, about my really BIG - Big Bore ...
http://forums.accuratereloadin...341045342#4341045342

Well, .... I added another really BIG, BIG-BORE to my collection. An 1895 model 3.6" Field Mortar. I had to build a custom trailer to transport the 545 pound rig, and its permanently mounted thereon.

Take a look at that "bullet" ... - WEIGHS 20 pounds ... 750 fps velocity ... 4,000 yard range .... THAT'S 2-1/4 MILES ....

No one is going to have a bigger gun than I.





















.

ORIGINAL LOADING DATA is listed as ... "HOWITZER" from 0 degrees to 40 degrees ... and as ... "MORTAR" from 45 degrees to 85 degrees

Might work for elk, a little small for Buffalo.

Just kidding of course. I love seeing your wares.

My father was a machinest at the Waterveliet Arsenal for 30+ years. He rifled the 1st atomic cannon and made numerous trips to the proving grounds in New Jersey.

You sure are the man. A fair bit smaller but I love your Winslow 378.

That would be fun with aluminum projectiles! Try to get to 2,700 FPS and put a scope on it!

Nice trailer carriage.
How far backwards does the trailer roll when you shoot it ?

hi, helmut..that's a very impressive new find!!!......i'd recommend a 6-24 nightforce scope in griffin and howe mounts for those long shots.!!!!!! very cool to see for an old artillery man!...best regards...JOHN

I wonder what the Taylor KO factor is on that one!

From which end?

You have to take that one out after coyotes.

I enjoy artillery and that is a pretty nifty find. I've only got replicas but they range from BB at .177" bore up to BB at 8.75" bore. My current favorite is a full scale 3lb breech loading swivel gun. It's been enough firepower to keep the pirates off the lake!

Maybe that is where WEATHERBY got the idea for many locking lugs ?

Now you have to start looking for a bigger gun.

Weatherby got it from Newton, who got it from Ross, who got it from artillery. More than a few other makers have tried the same interrupted screw-thread principle. It works, but it was more difficult to machine until CNC took over.

Now buckstix will find a suitable pipe with 3.6" OD, some crazy filler material and start making projos and lobbing them about the countryside!

He will be selling blank firings to attendees
at the local annual festival, to anyone who will pay for the BP used for the shot.

A friend has a Rem. 788 in .30-30 he has made into a BENCH REST RIFLE (new bbl, stock, etc,). He told me that most of the locking lugs have no contact !

But that is mass produced before CNC (I think) machines

That's sad. I'm certainly no Remington authority, but I believe the 788 was a budget model. Just because something is harder to do without CNC doesn't mean it can't be done; it just takes more human skill and time (and therefore more money) to do it. The 788 was built to a price, so not every last ounce of care and craftsmanship went into it. That's why they chose a rear-locking bolt; it's easier to machine the recesses in that location.

Years ago I toured the Pratt and Whitney plant for which we performed all the metallurgical testing and lab work. Automated inventory, robot carts whirring around the plant, a sea of CNC machines, it looked like the Blade Runner set. I came across a small group of non-CNC, old-fashioned (but brand new) manual machines. I stopped and talked to the man running an immaculate SIP jig borer, identical to one I had used back in school. I said it was not at all the sort of machine I expected to see there, and asked what type of work they did. He pointed to a cart with a few extremely sophisticated titanium castings and told me, "We fix up the CNC f***-ups." If one of the machining centres went a millionth of a frog hair out of tolerance, it was up to them to try to save the casting. CNC is awesome; it's not infallible.

that is pretty cool even the garage door and trailer are to scale. :-)

buckstix,
Have you tried out our modern BP to see how it compares to the most excellent powders of the 19th century ?
I wonder how the range of impact varies for those elevation angles, with a 20-pounder ?
What elevation gives the 4000-yard range of the original loadings, 40 degrees ?
I am pretty sure 90 degrees elevation might be too friendly a firing angle.
Friendly to the enemy.

I think I saw an identical item on a Morphy site. Helmut, you better bid to keep somebody from challenging you in the big bore race. I can see it now, a matched pair and a bigger trailer.
