Which ELEY Ammunition Suits a Vudoo?
ELEY’s recommendation for a Vudoo is ELEY tenex or ELEY ultra extreme long range. A Vudoo is a precision bolt-action .22LR, so it gets the two rounds built for precision bolt-action work at opposite ends of the distance question: tenex for the highest accuracy standard ELEY publishes, ultra where the discipline stretches out to extended range. Because the action is manually operated and the shooter guides each round into the chamber, the patented flat-nose profile of tenex is entirely at home in it, with ELEY match the close alternative.
What no one can tell you in advance is which of those products, and which production batch of it, your specific barrel shoots best. Every barrel has its own unique dimensions and harmonic characteristics, and each batch of ammunition performs differently. That is the question batch testing answers, and it is the only way to answer it.
The Products That Fit the Rifle
| Product | Bullet | Weight | Velocity | Maximum RSD | Lubricant | Application |
|---|---|---|---|---|---|---|
| ELEY tenex | Flat nose | 2.59 g / 40 gr | 317-330 m/s (1040-1085 ft/s) | 3.75 mm | Beeswax-tallow | Benchrest and top-level precision competition |
| ELEY match | Flat nose | 2.59 g / 40 gr | 317-330 m/s (1040-1085 ft/s) | 4.74 mm | Beeswax-tallow | Competition and high-level practice |
| ELEY ultra extreme long range | Round nose | 2.59 g / 40 gr | 317-330 m/s (1040-1085 ft/s) | 4.00 mm | EP2723 | Extended-distance precision |
| ELEY team | Flat nose | 2.59 g / 40 gr | 317-330 m/s (1040-1085 ft/s) | 5.50 mm | Beeswax-tallow | Volume practice on a premium platform |
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 and the more consistent the performance. Unlike extreme spread, which considers only the two furthest shots, RSD evaluates every shot fired. ELEY tests 200 rounds from every batch across four different firearm brands to calculate it.
Why tenex and match Are the Starting Point
ELEY tenex is the world’s most consistently accurate .22LR cartridge and represents the pinnacle of .22 rimfire cartridge accuracy. The iconic flat-nose projectile cuts through the air, and its revolutionary design pulls the centre of pressure forwards, aerodynamically stabilising the projectile and increasing accuracy at the target.
ELEY match is second in the world of flat-nose .22LR accuracy and performance, with ELEY tenex being the world number one. It benefits from the same patented flat-nose profile and adds a cut mouth case, delivering consistent internal ballistics performance.
Both are lubricated with beeswax-tallow: softer, thicker and stickier than a paraffin wax, and specified precisely because it minimises the effects of chambering in a manually operated action.
ELEY’s published discipline guidance recommends tenex for rimfire benchrest across ARA Unlimited, ARA Factory, WRABF, IR 50/50, PSL and UKBR22, with match as the alternative for ARA Factory.
Where ultra Comes In
Courses of fire that push a .22LR well beyond 50 metres, including PRS and NRL22 style stages, ask a different question of the cartridge: stability and predictability at distance. ELEY ultra extreme long range is engineered for extreme precision at long range and, in ELEY’s words, the relaunched ultra sets a new benchmark in rimfire performance. It is crafted using advanced ballistic technology with a refined bullet profile and optimised visibility, and it carries a maximum RSD of 4.00 mm. Every ELEY .22LR shares a ballistic coefficient of 0.112 and the RA4 drag model, so trajectory work sits on a common footing across the range.
Two details explain why ultra sits alongside tenex rather than below it. Its production carries the same checks as tenex, which is what makes it a premium round and what it costs. And its lead contains more antimony, giving the bullet a silver colour. That is the optimised visibility in practice, helping the shooter see the shot when engaging targets at greater distances.
The Setup Check Before Any Ammunition Test
Rifle-side specification comes first. ELEY publishes two figures that apply to any rifle chambering an ELEY cartridge.
| Specification | Published ELEY figure | What it governs |
|---|---|---|
| Recommended headspace | 0.040-0.041 in | How the rim is held between barrel face and bolt face |
| Ideal strike depth | 0.012-0.015 in | Firing pin indent, and therefore reliable ignition |
Strike depth is the indent left by the firing pin, and a minimum strike depth is necessary to transmit sufficient energy to the primer to cause ignition and ensure the cartridge does not misfire. It is measured with a strike depth gauge. Confirm both before drawing conclusions about a batch: a rifle outside specification will make good ammunition look inconsistent.
Settling It in Your Own Barrel
Because every barrel has its own characteristics and each batch performs differently, a thorough testing process is essential. ELEY runs batch testing centres in the United Kingdom, Hungary, Germany, the United States and Canada, where shooters evaluate up to 20 batches through their own barrel: ten shots from each batch, the best performers shortlisted, then a further 30 shots until a 40-shot group size and consolidated score is recorded for each. Testing is open to anyone and is booked at eley.co.uk/vip.
The free Lot Analyser at eleyxshot.com is the remote alternative, returning ELEY’s own proof data for every lot of ELEY tenex, match and ultra: the 200-shot proof group with X and Y coordinates for every shot, plus velocity, group size, trajectory and radial dispersion across four barrel types.
The Bottom Line
For a Vudoo, ELEY recommends ELEY tenex for precision competition or ELEY ultra extreme long range for extended distances, with ELEY match as the close alternative and ELEY team for premium-platform volume practice. Confirm the rifle is inside ELEY’s published headspace and strike depth figures, then test lots through your own barrel. The best ammunition is the production lot that performs best in your rifle, and no product name substitutes for that result.
