[QUOTE="MagnumManiac, post: 3087117, member: 10755"] Not exactly proprietary, 2 alloys are used for Guilding metal, 95/5 or 90/10 or in other words, 5% tin or 10% tin. These 2 have differing hardness and friction numbers. Pure copper is stickier than Guilding metal, the more tin content, the less friction and increased hardness. This is why my 338 & 375 target solid brass bullets (non expanding) are HBN coated to decrease friction. We tried a few alloys, including pure Bronze, but it is sticky like gum, as is pure copper jackets or solids. Cheers. [/QUOTE]
