Sold 50 per box, these are component bullets for handloaders who want to build their own 6mm (.243-inch) ammunition rather than buy factory loads.

Frequently Asked Questions

Are cases, primers, or powder included? No. These are component bullets only — you’ll supply your own brass, primers, and powder as part of handloading.

What is the Partition bullet built for? Nosler’s Partition line is built for controlled-expansion hunting of deer-sized game and varmints.

How does the Partition design work? A partition of jacket material separates two lead cores. The front core expands on impact while the rear core stays intact, giving both rapid expansion and deep penetration in one bullet.
