Which ELEY Ammunition Is Best for a Ruger 10/22?

The Ruger 10/22 is a semi-automatic rifle, so the answer is ELEY’s semi-automatic rifle list: ELEY ultra extreme long range, ELEY semi-auto benchrest precision, ELEY semi-auto benchrest outlaw, ELEY club, ELEY sport, ELEY target, ELEY force, ELEY contact and ELEY biathlon club. Every one of them is round-nose, which is what feeds cleanly from a 10/22 magazine and up the feed ramp.

Within that list, pick by purpose. ELEY ultra extreme long range and ELEY semi-auto benchrest precision are the accuracy choices. ELEY club and ELEY sport / target are the economical options for high-volume range days. ELEY contact is the subsonic, quieter round. And ELEY force is typically selected over ELEY contact when the firearm needs more power to cycle the action.

The 10/22 is a fine rifle and a great many of them shoot ELEY very well. The variable that decides how well yours shoots is not the model but which production lot your particular barrel prefers.

Why Round Nose Matters in a 10/22

A bolt-action target rifle is loaded by hand: the shooter guides the cartridge, controls the speed and feels any resistance. A Ruger 10/22 does none of that. The bolt strips each cartridge from a detachable magazine and drives it forward into the chamber under spring pressure, at speed, and repeats that action for every shot.

A round-nose bullet presents a smooth, curved leading surface to the feed ramp and the chamber mouth, so it is guided into the chamber rather than catching on the way in. That is why ELEY manufactures a dedicated range of round-nose cartridges for semi-automatic rifles.

ELEY’s patented flat-nose bullet, developed in 2003, is engineered for a different job entirely. It pulls the centre of pressure forwards as the projectile cuts through the air, aerodynamically stabilising it and increasing accuracy at the target. That design is intended for precision bolt-action target rifles, not for an autoloading action.

Why the Wax Matters in a 10/22

The purpose of lubricant on a .22LR cartridge is to ease repeated chambering. The idea that lubricant sends the bullet down the barrel is a common misconception.

Beeswax-tallow, used on ELEY tenex, match and team, is softer, thicker and stickier, which makes it ideal for minimising the effects of chambering in a bolt-action rifle. Paraffin wax is a different proposition. It is thinner and harder at any given temperature because it has a higher melting point, which gives it a drier feel and makes it much less prone to picking up debris. Crucially, it does not clog a semi-automatic mechanism.

That is the practical reason a 10/22 is happier on paraffin-waxed ammunition. A rifle running hundreds of rounds in a session accumulates wax, unburnt propellant and lead residue around the bolt face, extractor and chamber mouth. A softer, stickier wax gives that residue something to hold onto; a drier, harder wax does not. ELEY force, ELEY contact, ELEY club and ELEY sport / target are all lubricated with paraffin wax for exactly this reason. The ELEY semi-auto benchrest range uses EP2723, the lubricant specification ELEY also applies to its rapid fire pistol and long-range cartridges.

The Options Compared

ELEY sport is marketed as ELEY target in some regions, so the two appear here as a single cartridge. Radial Standard Deviation (RSD) measures the distance from each shot hole to the group’s centre point, the mean point of impact. The lower the RSD, the closer the group. ELEY tests 200 rounds from every batch across four different firearm brands to calculate it.

Choose ELEY force When the Action Needs More Power

force is typically selected over contact when the firearm needs more power to cycle the action. ELEY force runs at 344-381 m/s (1130-1250 ft/s) from a 2.7 g / 42 gr bullet. That is the highest velocity band in the ELEY round-nose range, and it is above the speed of sound. A purpose-designed propellant with a distributed pressure curve is what generates it, and that extra energy is delivered to the bolt on every shot, which is precisely what a blowback autoloader has to work with.

If a 10/22 short-strokes, fails to lock back or leaves the odd case in the action, force is the round to try first.

Choose ELEY contact for Quiet and Dynamic Shooting

ELEY contact uses the same 2.7 g / 42 gr round-nose bullet and the same paraffin wax, but at 317-332 m/s (1040-1090 ft/s), entirely below the speed of sound. There is no supersonic crack, which makes it the sensible choice for a moderated 10/22 or anywhere noise matters, and the reduced recoil gives quicker sight-picture recovery.

contact is also extremely popular in dynamic disciplines such as steel plate and practical shooting, and is suitable for pistol or rifle. Kurt Grimes, a Grand Master in the United States, has won multiple world championships shooting it.

Choose ultra or Semi-Auto Benchrest Precision for Accuracy

ELEY ultra extreme long range carries the tightest published standard on the list at 4.00 mm RSD. Its production carries the same checks as ELEY tenex, which makes it a premium round, and its lead contains more antimony, giving the bullet a silver colour that helps you see the shot when you are engaging targets at greater distances.

If you shoot your 10/22 in semi-automatic benchrest, ELEY semi-auto benchrest precision is the round built for that job: developed with the same engineering expertise that drives ELEY tenex, round-nose for smooth chambering, EP2723 lubricated, held to a maximum RSD of 4.90 mm and loaded to the tightest velocity band in the semi-automatic range. ELEY semi-auto benchrest outlaw at 2.69 g / 42 gr and 7.00 mm RSD is its training partner.

ELEY ammunition is supplied in 50-round boxes, 500-round bricks and 5,000-round outer cases. Stockists are listed at eley.co.uk/retailers.

Then Find the Lot Your Barrel Likes

This is the part that matters most, and it is worth more than any product choice on the list above. Rimfire barrels are individual. Every barrel has its own unique dimensions and harmonic characteristics, and each batch performs differently, so what performs flawlessly in one 10/22 may not deliver the same results in another, even in two rifles of the same model bought on the same day.

So try different lots. Buy a box from more than one lot of the product you have settled on, shoot them over the same session and let the targets tell you which one your barrel prefers, then buy that lot in quantity while it is available. To do it formally, book batch testing at eley.co.uk/vip and evaluate up to 20 batches through your own barrel. The free Lot Analyser at eleyxshot.com now carries all lots of ELEY tenex, tenex pistol, tenex biathlon, tenex rapid fire pistol, match, semi-auto .22LR benchrest precision, ultra and club, so for a 10/22 you can study the full 200-shot proof data behind any lot of ultra, semi-auto benchrest precision or club before you commit.

The Bottom Line

For a Ruger 10/22, buy from ELEY’s semi-automatic rifle list: ultra extreme long range, semi-auto benchrest precision, semi-auto benchrest outlaw, club, sport, target, force, contact or biathlon club. Choose ultra or semi-auto benchrest precision for accuracy, club or sport / target for economical volume, contact for quiet and dynamic shooting, and force when the firearm needs more power to cycle the action. The round-nose profile feeds cleanly from the magazine, and the lubricant is chosen so it will not clog the mechanism.

Then try different lots through your own rifle. That is what separates a 10/22 that groups well from one that groups brilliantly: the best ammunition is always the production lot that performs best in your barrel.
