When the target is past 100 metres and your discipline demands consistency, round-to-round variation simply isn't an option. The SK 22LR Long Range Match 40gr LRN Rimfire Ammo - 500 Round Slab is purpose-built for exactly these conditions, engineered to deliver the flattest possible subsonic trajectory without breaking the sound barrier, with the lowest achievable standard deviation and extreme spread in its class. Loaded with a 40gr (2.59g) Lead Round Nose match-grade projectile at a muzzle velocity of 1,106 fps, this ammunition sits right at the upper edge of the subsonic window, maximising ballistic efficiency while maintaining consistent, repeatable performance string after string. Whether you're competing in precision rimfire competition (PRC), tactical rimfire, long-range silhouette, or training on a .22 LR platform that mirrors a centrefire big-bore setup, this 500-round slab gives you the volume and consistency to put in serious work at the range.

SK 22LR Long Range Match 40gr LRN Rimfire Ammo - 500 Round Slab Key Features

• Calibre and Configuration: Chambered in .22 LR with a 40gr (2.59g) Lead Round Nose (LRN) match-grade projectile loaded in brass cases. Non-corrosive and designed to feed reliably through competitive target rifles and a wide range of .22 LR firearms.
• Muzzle Velocity and Energy: Rated at 1,106 fps muzzle velocity with 107 ft-lbs of muzzle energy, tested from a 26" (660mm) barrel. This places the round at the fastest practical subsonic velocity, maximising downrange energy retention without transitioning through the transonic zone.
• Ballistic Coefficient: G1 BC of 0.172 (calculated via Quick Target Unlimited Lapua Edition from V0 to V75), providing meaningful resistance to wind drift and velocity drop-off at extended distances where typical .22 LR ammunition falls apart.
• Long-Range Capability: Engineered with accuracy and consistency sufficient for shooting out to 300 yards (approximately 275 metres) and beyond, making it a genuine option for serious precision rimfire disciplines rather than a standard plinking round dressed up with match-grade labelling.
• Standard Deviation and Extreme Spread: SK's manufacturing process is optimised specifically to minimise SD and ES, the two metrics that matter most in precision shooting. Low shot-to-shot velocity variation translates directly to tighter groupings at distance.
• Consistent Ignition: Ultra-reliable shot-to-shot ignition is built into the primer specification, reducing the misfires and hang-fires that can disrupt strings in competition or extended training sessions.
• Barrel Fouling: The LRN bullet formulation is designed to minimise barrel fouling, allowing longer shooting strings without the accuracy degradation that builds as lead deposits accumulate in the bore.
• Feeding and Extraction: Dimensionally consistent brass cases promote smooth chambering and extraction across a broad range of .22 LR actions, reducing the likelihood of malfunctions during competition or high-volume training.
• Low Recoil: The subsonic loading keeps recoil to a minimum, making this well-suited to extended range sessions, high-round-count training, and shooters using .22 LR platforms to replicate centrefire technique and position work.
• 500-Round Slab: Supplied as a 500-round slab, offering a practical quantity for competition preparation and sustained training without the per-round cost penalty of smaller pack sizes.

SK has built a reputation among precision rimfire competitors globally for delivering match-grade consistency at a price point that makes high-volume training viable, and the Long Range Match load is the clearest expression of that. For Australian shooters competing in or preparing for precision rimfire disciplines, or simply demanding more from their .22 LR at serious distances, this 500-round slab is a dependable starting point.
