The .45 Caliber Muzzle-Loaders Hornady ELD-X Muzzleloading Ramrod Tip is precisely engineered to perfectly fit over the tip of Hornady Bore Driver ELD-X muzzleloader bullets. To ensure proper loading and alignment of the bullet as it is pushed down the muzzle a properly fitted loading jag is an absolute necessity. Unlike universal loading jag tips this jag matches the ogive of the ELD-X Hornady projectiles perfectly. Why does that matter? With a perfect ogive match, you are ensuring that the bullet and the ballistic tip are not damaged in any way during loading procedures. This ensures the bullet will perform as intended every time. If you are going to be using Hornady ELD-X muzzleloader bullets we highly recommend that you purchase one of these jags for both your bullet starter and ramrod to ensure proper loading and alignment. The all-brass construction of the ELD-X Loading Tip makes this jag perfectly safe for every muzzleloader barrel and will not scratch or damage the rifling. Additionally, the jag features 10/32 threads making it compatible with the vast majority of muzzleloading ramrods and bullet starters on the market today.
