Time to make the donuts....

[RGRobinett]

I was waiting to see what was said about them, anyway they are caused be an uneven pinch trim. if its not square you will get folds.

^^^^^^^ I'm with George on this - I had a LOT of, the seemingly defunct Hines, 224/.705" long jackets, purchased through Bart Sauter, which folded at about 30-40%! I had no sooner begun using that LOT, and was going to call Bart to learn what could be done, when, proactively, Bart called and advised
that I should stop using them, and return them. This was done, and the jackets returned to Hines, and replaced.

To avoid being completely left without .224 jackets, I retained one case of those jackets (10K+), and thinking that work-hardening promoted the folding, put them in the oven, punched-in the "draw back" program and looked forward to, "the cure" . . . the draw back reduced the failure rate to, a still unacceptable, about 25%.

So, I called and cried on George's shoulder - his advice was to put my pinch-trim die to good use . . . "AND THAT was the cure". Following pinch-trimming, making the entire 10K into a little shorter bullet, resulted in but a single fold. Powerful evidence that George was correct - and as, usual, pointed me toward a solution which cost me a little time, but saved me some $$. The 47 Gr. bullets shot GREAT & "sold like hotcakes" . . . Again, Bart/Hines replaced all of the returned jackets: excellent service AND excellent bullets. RG

P.S. Fold rates are generally 1-2 in several thousand pieces: occasionally, I've had a few irritating LOTs which folded at 2-3% - fortunately, "a few" is key those LOTs were FAR apart and far from the norm.

I'm glad it worked out ....

These are some good examples of how connected the bullet making community is....people work together to help each other out.

For example, I seat cores for use in the Robinett carbide point die on one of several Blackmon steel dies. Randy felt that having a larger post-seated jacket diameter would be of some benefit and suggested lapping one of the Blackmon dies a few tenths larger. After getting another core seat die from Larry Blackmon, Randy walked me through the process and I couldn't be happier with the result.

And George helped me out with info on punches, his theories on 'bump up' and a punch itself...a huge deal in the world of bullet making.

In modern parlance, this would be termed 'reaching out', 'collaborative efforting', 'results oriented focusing', 'networking', etc.

Damn, George - you KNEW it was gonna werk! You've been, "like a gold mine" - it's, sometimes, difficult to locate a vein, but when the, "right question" is asked, worth the admission price!! RG

The question of a short/long length jacket and folds came up. Here's what happens when your dies are set for pointing 1.00" jackets and .925" gets in the mix:

Washed the lube off 1,000 144 gr. .925's with acetone this morning. A smidge of color in the fresh acetone.

Good shootin' -Al

You can wash them fifty times and never get the jacket particles off and after every operation if you wash them they will show more....Al I thought you had that .925 vs. 1.00 jacket thing figured out with some weird double nut contraption...

Al, did the knock out pin go right through the met plate? If so, how did you get it out of the die? Or does it have a hole in the base?

Anyway, as of so far, we have not “crunched” a bullet on point up. I could attribute this to my phenomenal bullet making skills, but the truth is, I’m just darned lucky.

 

[geo.ulrich]

Jackie , they normally move fairly easy just pushing on the lead and you might or might not have enough at the bottom of the die to grab it and pull it off...

It felt herky and I knew right away what had happened....the ejector pin went into the lead core. Removing the shaft collar from the top of the ejector gave it enough extra travel so the bullet cleared the bottom of the die so I could grab it and give it a "...yerk and a jank", as my Dad would say.

Now, George...don't be dissin' my double lock nut lash up.

For anyone wondering what's the double nuts are about, it's like this. Going from the 1.00" to the .925's, the 'bizness nut' (bottom) is backed up against the top nut and lightly snugged. Then the top nut is backed up .030 from the 'bizness nut' and snugged down. The die then gets turned down and the marks lined up. The punch goes up and touches nuthin' but air. The rubber 'o' rings between the 'bizness nut and the die bushing and press are like free money. To go back to the 1.00", it's just the reverse....keeping in mind the to subtract the extra .030. Doing it this way, it will repeat the b-o within a couple thou. right away. Sounds complicated but it's not....works for my pea brain, anyway.

It's like running a firing order valve lash loop on the dyno...which we'll be doing over the next two days on a very good SBC 283 NHRA Super Stock engine package.

Rorshach 6mm core squirt die set up in a Ulrich converted Lee press. Makes very uniform cores. Tedious chore and not worth the time except to make small test batches. I will use the same press to core seat and a very old RCBS conversion to point up.

keep it simple buy them from Charlie ....

For anything in quantity, Hood cores are the only way to go.

Now that would be simple, if you could get them shipped to New Zealand for a reasonable cost

True enough Ian...

 

[D Coots]

And folks here bitch about the price of shooting....

 

[jackieschmidt]

I cannot imagine what it would cost to ship 100+ pounds of cores over 8000 miles from Georgia to New Zealand.

Yep part of the problem is that lead wire to be used for bullet making become ITAR regulated
So most importers won't ship it, some even with the right paperwork still won't ship it

To give you an idea of exchange rate at the moment US$450 is almost NZ$800 so by the time you factor that in this sport isn't cheap

 

[D Coots]

Remember folks, the only difference is OUR 2ND AMENDMENT.

I feel bad for shooters like you Ian.
