It doesn't get much better. Thanks Gear!

I do appreciate the tip to look at the archives. I have done a little bit of exploration. I do recognize the great collective wisdom there. I also know that I am a complete bullet lube novice in...

White mineral oils are very heat stable but they are pretty lousy lubricants and horrible as rust preventatives. They are sometimes used as high temperature additive carrier oils / base stocks. The...

For making Felix Lube:
There are so many different kind of white mineral oil. Some contain liquid paraffin some don't. Exactly what products seem to give the best results? Has anybody ever...

My rifle has the ballard grooves and 20 inch twist. Bullets are .432 diameter.

These days, most of my shooting is with a 444 Marlin lever gun with 265 and 300 grain Ranch Dog designed cast bullets. I have an old 450 Lyman Lube-Sizer. What hot and cold stick lubes would you...

Anybody ever cast a pewter bullet for use in those places that don't allow lead? Seems like the Tin - Antimony - Copper alloys ought to work OK, but the density is very low.

The BH number I reported seemed too low for a reason. No the core was not Jello. It's not even pure lead. (I confirmed antimony content with XRF.) It happened because of a mix-up in samples with...

Anybody ever check core hardness on a jacketed bullet? I just did for 44 cal Hornady 265 grain FP. I was surprised to find it was all the way down to 4 BHN. To be fair, this is not quite true...

Regarding direct reading Brinell testers, There is an ASTM spec on Brinell testers fitted with a indentor travel indicator; I think it is E103. I used to have such a tester that was used for high...

Well, Happy New Year and sorry for the late response. I do have a 10 mm ball but have not yet fabricated a proper holder for it. You are absolutely correct; the 100 Kg load used for the "B" scale...

The rule for Brinell impressions margin is 2.5 times the impression diameter from the edge of the test piece; so, it is hard to fit much of an impression on a boolit meplat. That doesn't mean you...

A couple of Brinell comments: (1) The load to ball diameter squared ratio is a critical characteristic of the measurement system. Brinell hardness measured at 3000 Kg with a 10 mm ball is exactly...

You raise an extremely pertinent point, JSnover. Where I WANT to wind up is somehow being able to generate hardness data that either is directly, or through conversion, equal to Brinell. Moreover,...

I'm a grizzled old metallurgist but just a new kid on the block when it comes to bullet casting. I do appreciate the helpful information. I'm leaning towards the CabinTree tester now, but because...

I wouldn't be too hung up on diameter of impression vs. depth. With a conical indenter, depth of penetration is linear with respect to strength. Rockwell C is an example. Brinell numbers are...

Engineers have a saying: "To measure is to improve." Data based decisions are only as good as the data. How much bias or noise is in the data? How well correlated is it to reference standard...

If you want to understand what Brinell testing is and isn't, a good place to start is ASTM E10. All the cheap lead hardness testers I've seen certainly are not at all compliant with that...

As far as I can tell from reading various posts of experiments, the LBT hardness tester may be about the best for measuring Brinell hardness of bullets. I wonder if anyone has tried to use a...

I'm curious how you came to select 60 pounds and a 5/32 inch ball.

Thanks for the posts Turbo1889 and Phaessler. I'm not sure why Lyman made a knockoff of an airgun pellet; so, I like the idea of the Lyman 575494 and the Lee 575470, but I'll spend a little bit of...

Yes Brinell is roughly linear with respect to tensile strength. Rebounding indentor hardness testers are not a new idea, but existing ones work by measuring coefficient of restitution as hardness...

I have an Ultraslug in 20 gauge and the Lyman mold for the 350 grain slug that looks just like the heavier one for the 12 gauge. I have not shot any yet. Are any of you guys into 20 gauge?...
