About Virtus Precision

Intro

This British company has been created from the ground up with the highest possible performance in mind for all disciplines of shooting. It provides all marksmen with the best possible performance from any type of projectiles including the specialist natures for the military and police. This company show-pieces the best Britain can offer and is a company that the UK can be proud of for years to come.

Background

The company was established in 2021 by one of the UK’s top aerospace engineers in partnership with an ex UK forces soldier with decades of experience as a military sniper, hunter and as a renowned international competition shooter. Combining countless years of experience from both founders, they created a company that will be second to none in the future. The combination of arguably one of Britain’s best engineers with a deep understanding of the shooting industry and ballistics, underlines the motto of the company: “Unparalleled Performance”

Products

The products offered are premium lathe turned projectiles utilizing the best equipment that is available on the market delivering unsurpassed quality control and match grade consistency from lot to lot. In other words, if you invest in this product it will be the same every time you purchase it and built to the tightest tolerances – no need for endless sorting and measuring of projectiles to ensure consistency

All calibres are tailored to the prevalent twist rates and matched to the specific setup in order to achieve correct stability factor number in order to guarantee stability and accuracy at any given muzzle velocity.

Virtus Precision Ltd are predominately creating lathe turned. However, special orders may be considered for future manufacturing of ammunition with the aim to create ammunition at a later date as standard.

Hunting Projectiles in the following projectile diameters:

– 6mm, .25Cal, 6.5mm, .270 and 30Cal.

Some calibres have up to three types of projectiles with different characteristics. Some calibres will have more than one weight per calibre of projectile being offered and expert recommendations will be offered for specific twist rates. More information can be gained on the website that will cover the three types of projectiles.

Larger calibres to cover both dangerous hard skinned and soft skinned animals can be created on special demand.

The following products are available:

Target Projectiles

This includes various sport disciplines such as Precision Rifle Series, F – Class, target rifle shooting and King-of-2 Mile competitions.

This product can also be individually tailored to a specific customer in order to exactly suit a specific twist rate of that weapon.

Larger calibres work better for copper monolithic lathe turned projectiles however stunning results have been seen in the hunting line projectiles like the .243 Winchester.

Specialist Ammunition Natures for Military and Police (Coming soon)

Various natures can be tailored to the customer’s exacting requirements for the weapons being used. This includes all military calibres. Expert advice can be given through Virtus Precision Ltd. through first-hand experience.

Tailored load development for estates, culling syndicates and Forestry Commission(UK).

Virtus Precision LTD can support any organisation in load development of group of specific firearms being used. The loads will be tested for safety by the Birmingham Proof House and safe, accurate commercial loads can be professionally loaded to the exact specifications to supply an organisation with the best possible ammunition.

Ballistic Classes for Long Range Shooting (Coming soon)

Three-day ballistic classes can be given to individuals with more complex classes available for military and police specialist requirements. This will include practical shooting at range on steel targets from different positions.

Deer Stalking in Scotland and South African Safari Hunting

Virtus Precision Ltd has access to some of the most exotic hunting experiences available. Why not combine a long-range shooting class with an organised hunt? All ghillies and professional hunters involved have been vetted and are recommended by Virtus Precision Ltd. Both locations have been used in the past by high profile individuals with great success.

Virtus Thoughts about ballistic co-efficient (BC)

Instead of the scientific definition that anyone can look up on the internet, in short ballistic co-efficient of a projectile means how efficient projectile will be down range. The BC number will determine how effective the projectile will be in terms of wind drift and the retaining of muzzle energy.

Most BCs known to rifle users are G1 and G7 numbers. The G numbers are linked to a specific profile of a projectile and the higher the number the better down range ballistics. The G7 number is more linked to the common boat tail design whist the G1 number is more linked to a non-boat tail design projectile.

Most people are unaware that there is virtually NO difference between a G1 and G7 number within the supersonic range of bullet flight. That is MACH 1.2 or 1340fps just before the transonic range of the bullet flight. To convert from a G1 number to a G7 number just simply times the G1 value by 0.512 or the divide the G7 number to get the G1 BC. It is that simple.

Information gained from an accurate BC number enable rapid wind reading formulas to be utilised – reading the wind incorrectly is the number one reason why targets are being missed at range. In short, the higher the BC number, the less accurate your wind reading abilities need to be – therefore the more you can “cheat” the wind.

BC is often a HUGE selling point of any manufacturer when selling ammunition or projectiles. The average consumer thinks that the higher the number, the better the bullet. However, this is not always true. If shooting game at ethical distances at no more than 300m BC makes very little difference. Let me explain:

If we compare two ordinary cartages in .308 Winchester 155grn launched at 2850fps. Let’s compare the following well known lead projectiles to prove our statement:

Projectile 1: Sierra Palma (2155) 155gr G1 BC: .418 or G7: .214

Projectile 2: Berger Target Hybrid 155gr G1 BC: .479 or G7: .245

The above BCs are the corrected average BCs after being shot through the same Doppler chronograph by Applied Ballistics.
Let’s assume the wind is 10MPH full value at 300m. Let’s also assume bullets are being shot from the same weapon after being zeroed at 100m and the conditions are at sea level or 29.92 inHg at 15C. All other variables like sight height and twist rate are the same.

300m or 328 yards
Sierra Palma (2155) 155grn
Berger Target Hybrid 155grn

10MPH wind drift (inches)
8.6” (or 21.8 cm)
7.3” (or18.5 cm)

Drop (inches)
14” (or 35.6 cm)
13.4” (or 34 cm)

BC Conclusion

As you can see from the table above. How much is BC applicable? If you take into consideration the possible shooter error involved, then the very marginal differences get lost in the “noise”. Especially when considering all the other variances like rifle accuracy, it becomes almost irrelevant.
Even though the differences in BC’s is quite big, we have a 1.3” difference in wind drift and a mere 0.6” difference in elevation between the two types of projectiles! Within reason the exact same can be said for muzzle velocity variation in regard to the extreme spread and standard deviation of ammunition.

Other considerations

What is more important at distances shorter than 300m is to find an accurate load for your rifle and bullet combination. This is where a theory of a group will be far more applicable at short range compared to longer ranges where a multitude of other variances start being a lot more important. A theory of a group where the group size grows proportionally to the size of a group becomes far less applicable at range due to the multitude of other variances like extreme spread and standard deviation of the muzzle velocity and BC variation from one round to the next.
BC however does matter at distance. The example above is just for deer stalking or hunting.
Besides G1 and G7 drag curves, the custom drag curve for a specific bullet is better. Especially when shooting the ultra-long distances and if the firer shoots in the sub-sonic range of the bullet it certainly has its advantages.

The next drag curve even better than a custom drag curve for a specific projectile will be a custom drag curve for the same bullet but from a specific barrel. Every barrel will also have a slight effect on the BC of a projectile. Competitors in the King-of-the-2 Mile will benefit using this particular drag curve and it is most of the time almost irrelevant for other disciplines of shooting.
Accurate BCs can only be taken from the most accurate Doppler radars on the planet. We at Virtus Precision Ltd highly recommend using the Applied Ballistics BC library on the internet to get the correct ballistic co-efficient values of all projectiles. Too often, bullet manufacturers will inflate their numbers and only end up confusing their customers when they start missing targets at range and cannot explain why.

Another way BC’s can be obtained is via a mathematical formula and trueing your BC. If obtaining BC via maths, numbers will most likely be inaccurate and is at best a prediction rather than a certainty. At this time Virtus Precision Ltd will be truing the BCs. This method is accurate IF you know how to do it. Please do not rely on this method if you do not fully understand this method otherwise the numbers will be corrupt.
Recommendations:
What is very important is KNOWING the characteristics of your projectile. Impact velocities especially for copper monolithic projectiles are extremely important to determine terminal performance. Why is terminal performance important? Well, good terminal performance, ensuring good ethical kills following a stalk at the correct recommended muzzle energies.

For example, if your bullet manufacturer stipulates that expansion will stop at 2200 FPS impact velocities, you HAVE to study what range this is likely to happen at, by looking at the remaining muzzle velocity of that specific projectile from your rifle. If you do not know your effective range, you will get shoot-throughs, meaning the bullet will stay intact whist passing through the vital organs of an animal when hunting without the desired terminal performance. This will end up in wounded animals – not something any true hunter wants to experience.
Apart from not having the ability to read the conditions of the day, most hunters fail to really “study” their equipment. Virtus Precision classes will address this and many more aspects in the future.
The most important aspect by far is learning to read the wind. This remains the biggest variable for any longer-range engagements. If you have to aim off for wind at any animal, then we suggest get closer! Ethical hunting is what we will always continue to promote at Virtus Precision Ltd.
