Just curious Nick, how did you find it was 3-5 BHN off?
I wouldnt think 3-5 would really make any difference.

I also own the LBT hardness tester, but wanted to try the Lee because it derives the number from the definition of BHN. I was hoping it would be more accurate. Instead, the LBT told me some commercial cast bullets that claimed to be BHN 16 were at right around that hardness, while the Lee told me they were BHN 21. Trying it on other alloys ranging from pure lead to Linotype also got me numbers that were too high.

To be fair, I haven't tried to calibrate the spring force on the ball. Been waiting until I have time to put a strain gage on the press I use it with. I've done the computations from the BHN formula, and if the spring is accurate the numbers say it should be working, but it isn't. And if mine isn't, I would assume others may not be, either.

Is there any printed instructions on installing gas checks on Cast Bullets? I must have a couple thousand that were sold to me prior to me knowing enough to say......Hey, I think these aren't load ready!

First, you seat them squarely, like this:
If you don't have a couple of seater stems, you perhaps can just snap them on with your fingers and tap the bullet on the desk, or lightly with a small mallet to seat, if it fits the shank really well..... but this is not always the case. Every shank is just a little different, depending on mold size, alloy, temp of casting, etc.

Then run them through a Lee push-thru sizing die to crimp them onto the bullet. That is the simplest way.

If you have a Lyman/RCBS lubrisizer, the technique is a little different. Let us know what equipment you plan to use.
Have a Colt and a smile.
