My 30 caliber "Glazer"

Rangefinder · June 14, 2012, 04:47 PM

Had a little "experiment" go really well. I was recently loading for my neighbor's 5.7x28 in return for a bunch of roofing he's supplied me with (among other things). After a lot of very careful work on the project, we decided to scrap it before finishing with a $1200 hand grenade. So I have all this 5.7 brass laying around....

Running with Brian's 300 Win Mag trials, I decided to see what kind of fun I could have turning these stupid little cases into FL gas checks. So, I cut the shoulder off to a respectable length. Then I pushed in some #7 shot, dropped in an airsoft pellet, and squeezed 'em carefully into a 220 Swift FL sizing die with the decapper removed to form a basic Truncated Cone. Lastly, I ran 'em through a .311 sizer (finished at .312 after spring-back), and finished with a weight of 95.0 to 95.4gr on the small test batch. Originally I was intending to run them in my AK, but thought I'd push the trial run through something a little heavier--so I loaded one for my Mosin over 51gr. H335 (Data for a 110gr jacketed), and squeezed one off with a little hesitation. Not only did it fire well, and accurate, but the results on the dry-pack were simply amazing. Not target photos yet because I was too excited about it to bother with the camera. Photos of wet-pack tests coming very soon--just wanted to get this up right away. NOW I can go do the more scientific documenting stuff.

You'll note the nose is a little crooked--next batch will be run through the case trimmer to square them up better before forming--I was more interested at how well they would form up last night so I skipped a few things. Next run should be a LOT more pretty now that I know it has potential and don't mind spending the time on it.

Continued this afternoon...

HOLY CARP, BATMAN! What an insane bullet!

So I squeezed out a few more this afternoon with careful trim length, etc... Then I wet-pack tested one... So, with a couple plastic jugs crammed with wet paper and then topped off with more water, I sent one of these crazy little buggers into 'em.

Here's what it started out looking like...

Here's what I managed to recover from the middle of the second jug.

And then there's the first jug--or what's left of it. I heard "plop-plop-plop" for a good second or two after the hit from falling globs of soggy paper still falling. I have no idea where the lid to the coffee jug landed--could be in the next county, I never saw it after impact.

Now, the job is to dial in the load to tighten up the accuracy. It's gonna be limited I have a feeling, just by the nature of not having a solid core. But this bullet is gonna be truly frightening against any unsuspecting yote.

That is 100% bad-ass, and brings a wide grin to my face

Rock on!

Very cool. My knowledge of reloading and all that is very limited, but it's always cool to see someone try something new.

I feel very uncreative after having read/seen this. Nicely done!

Rangefinder · June 15, 2012, 11:49 AM

Update: After it performed well enough in the Mosin with a stiff load, I felt comfortable loading a few for the AK. With that nice rounded airsoft pellet tip, they feed very well--takes a stiff crimp to keep solid neck tension and prevent set-back though. Looks like I'll be building a basic canalure tool next. With 15gr. 2400 these little buggers fed and fired through the AK with average 2000fps of explosive authority, and it also dropped my brass in a nice little pile about 8' away rather than send it into the next county. Oh, this is turning into a fun little project! Guess I'll have to cut a core mold now so I can make some solids and partitions.

Rangefinder · June 15, 2012, 01:49 PM

Oh boy, did I figure out something else cool---These slip right over and crimp tight to a 6mm 100gr. soft point to make one really hard-hitting 150gr. sabot! No photos of that one yet since I need to get to work. BUT---they're coming.

armoredman · June 15, 2012, 01:54 PM

That's fascinating!

Rangefinder · June 16, 2012, 01:05 AM

I think I've solved my canalure issue...

So I was thinking tonight at work, putting together in my head all manner of complex mechanical things that would over-complicate any and all projects... And then it hit me---K-I-S-S... Keep It Simple Stupid. I use a pipe cutter to initially cut the shoulder off the 5.7 brass before I trim and seat whatever core I'm using. The first twist with the pipe/tubing cutter pushes a groove all the way around the soon-to-be jacket before I tighten it again and continue cutting. Problem solved! Intentionally dull the cutter wheel of a tubing cutter so it will "dent" but not cut, even notch it if you will, thread a stop-nut onto the tightening handle so it only squeezes so far, and... BINGO!! A poor man's canalure tool!

No photos to share yet because I haven't made it out to the shop yet since getting off work... BUT, they're coming as soon as possible.

Just sharing the thought!

this is Awesome, please keep posting pics.

also have you started a blog yet? this kind of stuff could definitely start one

That's just hilarious. I applaud your craftyness.

I remember reading about Glaser rifle loads in a Gun Digest when I was a kid. The concept seems much more sound compared to the lightweight, relatively slow moving, underpenetrating pistol versions.

With a little tinkering I have a canalure tool now.

I took the rotary blade out, spun it with a belt sander till it had a nice flat edge. Then took the tubing cutter to the drill press. A quick hole, tap, screw, and a couple nylon bushings with lock washers sanded to make the depth I wanted, and BINGO. Works like a charm.

How does it look after finished? Like this:

that is mad science at it's finest.

Is there enough room to do the same thing with a 6.5mm/.264 bullet? They tend to be long for the weight and have a high SD and fairly decent BC as I recall.

No telling--but it'd be easy to check after I trim one. I bet it would stuff in pretty easily. I'm going out to trim some cases tonight so I'll see what the average interior diameter is on a prep'd before my initial sizing.

EDIT---interior diameter is .269 average before running through a .311 sizer. SO, a 6.5 would sabot very well.
