You can get Sally Hanson's Hard as Nails at Wallgreens, CVS, or your local grocery store in the cosmetics section.

After putting calipers on newer boxes of Hornady Black and Hornady Custom ammo there doesn’t appear to have any crimp applied, unless they are using a different method that isn’t contacting the case mouth. It measures the same as my uncrimped reloads.

That is indeed an enigma. The only possible explanation that comes to mind would be the fact that they are using new, unfired brass that has not been work hardened or stretched during ignition, then resized. Brass being a ductile metal. Otherwise, your guess is as good as mine. FWIW, a quality micrometer is generally a more accurate measuring system than a digital caliper.

What was the actual reading you got?

All of them measure .477-.478. I was getting a measurement off my crimped loads at .474-.475 and uncrimped at the same .477-.478 like both box ammos.

What I do to cup-core bullets is do a double cannelure (side by side) using Ultimate Cannelure Tool then use a stab crimp....using a kinetic bullet puller it will take 5-6 very hard wacks to get a bullet to move...10 bolt drops on a AR-15 the bullet might move .005"....

I been in contact with Kevin to see about making a V- roller for the Ultimate Cannelure Tool so that a "V" can be rolled in the case after bullet is seated to secure in the cannelure of the bullet....no stab crimp needed...

If interested in purchasing a Ultimate Cannelure Tool....http://castboolits.gunloads.com/showthr ... elure-Tool

Couple videos on Ultimate Cannelure Tool

Also though about putting a Cannelure in case like 9mm 45 ACP ammo to stop bullet going deeper in case hitting feed ramp....

Using Cutting Edge Bullets Copper Raptors I put the stab crimp in one of the groove of the bullet..
