I know the feeling, I have broken my share of reamers [smilie=b:. With 4 flutes .224" reamer tips get really thin, so my latest reamer is 3 flute :wink:. Keep up the good work.

Loaded with 13.9 grains of Vihtavuori N130 and Lapua D166 200gr FMJBT, my Sako M92S cycles perfectly, velocity is 1000 fps and accuracy close to full power 123gr FMJ loads.

It sure can be done.
First draw takes lots of force, and then it gets easier.
I get my jacket material by raiding scrap barrel at work :wink:. There isn't much, but enough 0.031" copper and brass...

Manleyjt,

Thats the idea.





Short answer, washers and shims :bigsmyl2: I like simple solutions.
These pictures show how parts fit together.

This is what I did.
0.1" thick HSS papercutter blade cut to shape. Works fine on aluminium, with bigger calibers.

Reamer and mold cut with it....

Manleyjt,

Once more you got it right.

1 ½"-12 thread on RCBS and Hornady .50 BMG dies.
1 1/4"-12 size is big enough for lube channels. Problem is, how to control lube flow during sizing operation. Not so easy if using H&I dies.

...

Thanks again, need to make few tests to find out proper depth, starting with 0.015" and going down from there.

Next bit starting to take shape. If shimming doesn't work, I must make one of these...

Thanks to you all.
I was thinking about 0.02" as max depth for groove.
Teeths on my cannelure wheel are about 0.015" deep and 0.02" apart.
I was thinking about using stainless steel shimstock...

How deep should cannelure groove be?
I'm building cannelure tool and would like to hear what works, before making all parts.
Any help appreciated.

I made one few years ago, but it was 1 1/4"-12 thread size.

DukeInMaine,

You are right, it's simple way to trim cases and really easy to smash cutting edge, if not properly set. But when properly set there is no problem, and it's easy to make new bushings....

Here is my pinchtrim die to trim .38 spl cases. Just add correct lenght and diameter bushing to trim other caliber cases.
Lenght adjustments should be easy with hot glue and washers :mrgreen:.
...

It is :grin:[smilie=w:

And since I don't need pinch trimmer for .38 spl cases, I can send it to you.
I need to cut it to correct lenght, make little modification to cone die and heat treat...

Just for fun I made pinch trimmer for .38 spl brass.

Just one of my :redneck: ideas, but how about modified pinch trim die.

Bullseye93,

I will post whole story on jacket drawing, once I get all my tools and dies to working order and to bit more practice on how it's done.
What I can tell you is, that it's not that hard...

I have a question about .50 BMG bullets.
How thick should jacket walls be ?
I'm thinking about drawing from 0.03"-0.04" brass sheet. Would it hold together ?


Kaj

Thats why I use 7 ton log splitter, some old shock absorber rods, few feet steel bar and chrome moly steel for dies :-D. I'm cheap ;-).

Just got an idea :idea:. What about my original idea on lube flow control turned upside down?
