SinterFire Next Generation (NXG) 10mm Auto ammunition (brand part no. SF10125NXG) loads a 125-grain lead-free ball bullet in a brass case, giving 10mm shooters a lead-free training option built for reliable feeding rather than the fragmenting performance of SinterFire’s frangible SD line. Where the Special Duty frangible bullets are engineered to disintegrate on hard targets, the Next Generation ball round holds together and feeds much like a standard full metal jacket, making it a practical everyday practice choice for ranges that require lead-free ammunition without needing frangible-specific performance. That combination of lead-free construction and standard-style feeding fills a gap between frangible and conventional practice ammunition. For 10mm shooters who need lead-free ammunition without frangible construction, this handgun ammunition from SinterFire is built for exactly that.
