Zink/Copper alloy jacketed bullets
« on: November 10, 2024, 08:32:37 PM »
I just saw RMR is making silver jacketed bullets with a zink/copper alloy have any of you tried them?  They are about the price of copper plated or Hitek coated bullets. With the high cost of copper they my be a good alternative.

See RMR web page:  https://www.rmrbullets.com/

Look for their name "Idaho Silver". About $20 less per 1000 !!

A common alloy of zinc and copper — often 1/3rd zinc and 2/3rd copper — is brass. Current spot prices are: zinc — $1.36/lb; copper — $4.29/lb. Brass is more corrosion resistant than copper, and it is stronger (resists deformation more) than copper.

I have not tried any but read the listing on the RMR site. There are a couple notables regarding the use of these. https://www.rmrbullets.com/shop/bullets/pistol/9mm-355/idaho-silver-9mm-120-jhp-nuke-read-full-description-before-ordering/

 Well I broke down and bought a couple thousand of RMR's new silver zink jacketed 9mm 130gr FMJRN bullets. They ran through my Mr. Bullet feeder and loaded just like my old stand by RMR 124gr copper jacketed bullets. When I shot them they felt the same as the copper and the POI was also the same. Clean up was easy so I'll be buying more in the future.
