Hood Cores - Just how accurate?

I have just taken a small sample of 25 Hood cores, and weighed them for accuracy. The sample was only 25, but I feel this is enough to give us a good idea of what to expect. Target weight was 79.0 gr. Results are:

Lightest - 78.968 gr.
Heaviest - 79.016 gr.

Total variation - .048 gr.

You might just say 1/2 of 1/10 gr.

As said before, you'd be hard pressed to duplicate this kind of accuracy with your own squirt dies.

Thanks Charles

I have ordered 112 and 118 grs' from Charlie and have been happy with both. The cores arrived in a timely manner and the product is great. Just another satisfied customer.

I would like to see how Charlie does that, I can keep mine within a tenth, but it is very time consuming. I bet Charlie does his in a 1/4 of the time it takes me. With that being said, if you are weighing every core or bullet that you buy, you need to get a pet or a high maintenance girl friend if you aren't married or a second and third job.:eek:

I wish I had a scale like Michael has, that is that accurate.:)

what is he using to cut his cores so accurately and in such large quantities?

That's simple, Charlie told me @ a IBS shoot in Elberton Ga a couple years back what he use's to make all those cores and keep the quality on track............................. he use's Mrs Hood,,, Cheryl does the cores,,,,, sorry Charlie I let the secret out the bag,,,,,,,,,,,

the wind is my friend,,,,,,,,,,,,

All I know is, if it doesn't go into the squirt die at consistent weight, it won't come out of the squirt die a consistent weight either. The closer the rough cores weigh to one another the better. I think a very solid "stop" on the core cutter helps to prevent flexing as the wire is fed through the cutter.--Mike

Yep, on all counts. -Al
 
I'm certain that Charlie's press design has less stretch than ours do. Even a positive stop on the bottom of the squirt die could do wonders for the accuracy of the cores. When you see a variation on the weight of a squit core, you can mic it. If it is heavier, it will mic longer. I'm certain that a few people would like to know what scale I use. It is a Acculab, but the upper line of analytical laboratory scales. Some have even finer resolution, but mine at .002 gr. is fine enough.

Here's a link that Randy put in another bullet making related thread on here recently, with pics of some good looking core cutters IMO..and lots more good info and pics. http://www.bench-talk.com/photos/r_g_robinett/picture773.aspx If you're using a cutter with a light piece of angle iron and a 1/4" bolt as a stop, just feel how flimsy the stop is. Watch it move when you lightly push the lead wire against it.--Mike
