Outer Edge Target Projectiles

The Outer Edge Projectile  (OEP) bullet range is designed and manufactured in Australia with some of the best technology used anywhere in the world today.

Target Projectiles - Transonically tuned for ultra-long range precision Outer Edge precision CNC copper bullets are stunningly accurate over distances that challenge conventional high BC bullets.

Most high BC bullets are subject to enormous destabilisation as they transition from supersonic to subsonic flight. Outer Edge Target bullets have been designed, engineered and tested to be as stable as possible, and continue to deliver tight groups right through the transonic zone out to ranges well beyond.

OEP Target projectiles are not suitable for hunting applications. What are the qualities of OEP Target bullets? OEP bullets are precision CNC turned copper projectiles coated with an advanced proprietary coating (not moly) designed to deliver the following benefits.

In addition to superb accuracy and transonic stability, the added benefit of higher velocities typically achieved from lighter, magazine fed OEP bullets outweighs any difference in BC when compared to conventional bullets. It doesn’t take much velocity to trump BC in terms of better wind bucking ability and trajectory. Use your ballistic software to compare!

The big news for our single shot bullet range (indicated by **) is that the BC’s are amongst the highest of any commercial bullets in the same weight class. Indeed they often exceed the BC’s of much heavier bullets of conventional design. A double bonus of higher velocity and BC. Again, we invite you to calculate and compare the competitive advantage!

Specifically designed to match the twist rate in your rifle. Bullet stability is critically dependent on a barrel’s twist rate. OEP have a dedicated bullet designed for your cartridge and barrel combination. The barrel twist rate required for each bullet is identified on the packaging.

Have ideal Shot Start Initiation Pressures (SSIP’s) – producing consistent ignition this is the foundational for accuracy.

Consistent from batch to batch. Coated with an advanced proprietary dry lube coating that, unlike moly, is easy to remove when cleaning. It is non-corrosive with a low coefficient of friction; keeping your barrel cooler and cleaner for longer. Testing to date demonstrates longer shot strings are now possible under competition conditions. Cold bore and group consistency is greatly improved.

There is an OEP Target design intended to maximise performance for both magazine and single feed target disciplines in most commonly used calibres. Easy to develop loads for, when our recommendations are followed.

Loading tips

1.       Bullet seating - All OEP Target projectiles show a distinct preference for being seated between 0.9 and 1.3 mm (0.035 - 0.055”) off the lands. This is common with copper projectiles. Many shooters report groups in the 0.2’s and 0.3’s (MOA) with OEP bullets seated within this band. Seating bullets further off the lands is no significant disadvantage, but closer to the lands may increase pressures and reduce accuracy. The normal place to start will be to seat the bullet to the junction of the case mouth at the base of the hybrid ogive or the next band. At least three bullet bands should engage the case neck to minimise runout.

2.       Case preparation – To ensure proper and consistent bullet seating depths, cases should be all from the same batch, trimmed to length, externally deburred and the case mouth chamfered. Use of highly consistent, quality brass is essential.

3.       The importance of barrel twist - All OEP bullets are precision matched to a specific barrel twist rate. This recommendation is labelled on the box. Using the correct bullet for the rifle will produce the best results. At ranges of less than 500 metres, the use of a faster twist is fine. Use of a barrel with a slower than recommended twist may not achieve adequate stability at low temperatures on the coast (high air pressure zones). It should be noted that bullets with a Sg of less than 1.5 (Miller gyroscopic stability formula) at launch, will also be discounted in their BC value. All OEP bullets have a Sg of 1.5 or greater when used in conjunction with the recommended barrel twist. Calculations are based on the universal standard for air pressure; sea level - 1013 mb @ 15° C.

4.       Primers - Use your normal primer. Use of magnum primers is not required unless recommended for a particular cartridge. Match grade primers are highly recommended.

5.       Precision bullets require precision barrels - The best bullets in the world will not compensate for a worn or out of spec barrel. Standard land and groove configurations are preferred to polygonal or canted lands.

6.       Load data - Whilst OEP  do substantive load development  and product testing , our greatest challenge; as for all reloading component manufacturers, is that we have no control over the standards and tolerances of supplies produced by other manufacturers, or the reloading practices of our customers. The biggest issue however lies with the most basic component the brass cartridge case. Brand “A” may be great brass of the highest standard, made to exacting specification and tolerance, whilst brand “B” might be almost as good, but substantially different in volume capacity. We have measured discrepancies exceeding 7% between brands in the 308W and 300WM alone, and this of course poses substantial challenges in recommending safe and accurate load data. Never mix your brands of brass, and always check for variation in and between batches, even when using the same brand of cartridge cases. As such we are happy to provide the brands of components used in testing, and those we found to perform best. We cannot however suggest a powder charge without the provision of a precisely measured case capacity (measured in h2o – distilled water).

We strongly recommend the use of a good reloading manual, in conjunction with sophisticated electronic predictive load programs such as QuickLoad®
