Through a proprietary sizing process that creates a unique geometry, NSR bullets provide bullet to bore performance with load and shoot convenience without sacrificing performance.
While the NSR bullets do allow for variations in bore diameter, they are only able to accommodate a limited range. They were designed to work with Brux & Bartlein barrels. See below list for feasibility of use with other brands of barrels.
Should work but has not been tested: Rock Creek
NOT RECOMMENDED FOR USE IN FOLLOWING: Preferred, CVA Paramount, McGowen, Pac-Nor: may work in some cases, but generally will not as barrels on these guns all typically run substantially looser or tighter than a Brux: Pac-Nor: May work in some case
For ease of loading, there are two sizes (large & small diameter). Recommend starting with smaller size; and if not enough loading pressure, bump up to the large size. Test pack available for testing.
The Arrowhead NSR line has proven itself on the range and in the field. The unique hybrid ogive maximizes the ballistic coefficient while maintaining excellent shootability. 0.021″ Jacket Thickness produces excellent terminal results on game at all ranges. If you’re looking for maximum performance out of your muzzleloader, this is the bullet for you!
