.458 HOMEBUILT GUN — NEW BULLET MOLD
THIS WINTER I BUILT A NEW GUN
.458 CAL. 44 INCH LONG BARREL.
I WAS PLAYING AROUND WITH A BULLET MOLD TODAY.
HAD AN OLD LEE MOLD FOR 30 CAL M1 CARBINE LAYING AROUND. SOLD THE GUN MANY YEARS AGO.
I MACHINED OUT THE MOLD FOR .458
PLUNGED DOWN WITH A .437 BALL ENDMILL, THEN CUT 2 DRIVING BANDS AT .460.
THE BULLET AND GUN COMBO MAKES 951 FPS, AND THE BULLET WEIGHS 380 GRAINS. THATS 763 FPE ON A 3100 PSI FILL.
THIS THING HAS HUGE RECOIL!!!
SEE THE RECOVERED BULLET, SOFT LEAD, SHOT INTO A CATALOG – IT DOESNT EVEN LOOK LIKE A BULLET ANYMORE!.
THATS A .22 KODIAK PELLET FOR SIZE COMPAIRSON.

its gonna go right through….i shot my .458 into a pc tower cabinet….it tore through both sides soft china sheet metal, through the PSU (2 sides and electronics) through a crossbeam…and out the other side….and deformated to a lead splatter on my 1/4″ steel backstop !!!
if the 6×6 is hung and placed so it can move it might not tear all the way through….as a lot of the energy will be converted to motion, but if its places so the wood cannot move…right through no doubt !
and thats with just 350-400 fpe and done before i got to 600 fpe….MM’s rifle is way more powerfull
😯 Awesome rifle!!!! Please do a video of it’s effect on a piece of 4×4 or 4×6….please 🙂
wow!!! talk about recoil!!!
cant wait til ur finish with it…
make sure you post pic of it when ur done… 😆
That’s monster power!
Your slugs look like they’re coming out great. I like the round nose design at 380 grains. If you’ve plans of casting in quantity I would be interested in buying a few off of you.
I’m hoping Dennis will call soon.
I have another reason to be excited for deer season, i can’t wait for this years pics and story. Get that thing ready! Maybe add a video camera mount? 😀 I predict a bang-flop this year. That things a beast.
Thats a big lump of lead ! 😯 i think the phone book in the vid is mortally wounded 😀
Wow that was friggin awesome!
That was awsome, well done good sir.
id love to see a video of it shooting tagets and the devistation it causes
😀
Looks like it had a pretty good kick! Thanks for the comments also.
Holy CRAP! That was awesome!!
I watched it three times laughing to myself. Not because it’s funny, but because I don’t know what else to do. The power of your handheld air-cannon is simply incredible. 
Also, that’s a sweet little shop you’ve got there. 
Yup.
She-bang!
Thanks for the vid, pretty damn cool!

Big file, takes time to get it.
750 FPE shot, .458 caliber, 380 grain bullet.
That white square is a 4 inch thick catalog in a cardboard box.
Nice…..

O.K. is that a working gattlin gun cannon in your pic? You probably made it also. 😀
