The Outer Edge Projectile (OEP) bullet range is Australian owned and manufactured for Australian game and hunting conditions. They are designed and manufactured with some of the best technology used anywhere in the world today, to deliver dependable performance and stunning accuracy. The Hunting range has been engineered to produce devastating results on medium to heavy game — anywhere, anytime.

OEP bullets are precision CNC turned copper projectiles coated with an advanced proprietary coating (not moly) designed to deliver the following benefits:

  • A dedicated bullet designed for your cartridge and barrel combination to deliver precision and devastating performance.
  • Consistent expansion qualities that penetrate deeply, maximising the wound channel from any shot angle. 120% calibre expansion is typical of OEP bullets at normal hunting distances.
  • Designed to feed reliably in all types of rifles and magazines
  • Coated with an advanced proprietary dry lube coating that (unlike moly) is easy to remove when cleaning. It is non corrosive, keeps your barrel cooler and cleaner and reduces wear.
  • Nontoxic – a comforting feature for those who consume their harvest
  • Easy to develop loads when the manufacturer’s recommendations are followed

OEP – Devastating Hollow Point Hunting Bullets

The hollow point cavity design reliably produces a classic mushroom for that ‘drop to the shot’ wound channel, from ‘patting’ distances out to the 500 metre limit. Weight retention is exceptional, even when fully expanded.

OEP – Dangerous and Heavy Game Hunting Solids

OEP solid hunting projectiles are intended for short range hunting of heavy and dangerous game. They are perfect for buffalo and scrub bulls or that once in a lifetime, overseas dangerous game hunt. The large flat meplat (nose) of the bullet produces maximum wound trauma and penetration under the most adverse conditions, and against the toughest of game. When you have no choice but to stand your ground, OEP Hunting Solids will get the job done — emphatically!

What to Expect Using OEP Copper Hunting Bullets

Copper has a lower weight when compared to lead.

This means that copper bullets with the same displacement as a conventional jacketed lead bullet will be lighter and faster. We don’t buy our shoes by weight; we buy what fits our feet and what we are going to do with them. So it should be with our bullets. Bullets need to match the twist rate of the barrel and the intended purpose. A bullet’s displacement and performance is of much greater importance than its weight.

As a general guideline, it is worth considering going down the next size in terms of bullet weight when using copper bullets. E.g. if you are used to using a 150 conventional projectile in your 308W for general hunting, you might consider a 130 grain bullet when choosing from the OEP range.

Full Details on accounting for the variation between copper and lead core projectiles

Copper is considerably tougher than lead.

This means that even when fully expanded, copper bullets tend to shed much less weight than a conventional bullet and generally penetrate deeper and straighter as a result.

Velocity “trumps” BC.

Higher BC performance can easily be matched, if not completely overtaken, by lower BC bullets travelling faster. This is especially true over hunting distances of less than 300–500m. Use a Ballistic calculator and run the numbers to see for yourself. A further point to consider is that conventional bullets with high claimed BC’s tend to have very small meplats (bullet tips) and often require higher velocities to expand reliably, reducing effective terminal performance range even further.

Loading OEP projectiles

Bullet seating 1.

First and foremost, hunting projectiles of any description should never be seated into the lands. This is fraught with danger should a projectile become lodged in the throat of the chamber, especially unnoticed. This is all too easily done when focussed on the hunt.

Bullet seating 2.

All OEP projectiles, regardless of type show a distinct preference for being seated between 0.9 and 1.3 mm (0.035–0.055") off the lands. The aerodynamic shape of the two-band system is designed to achieve this outcome and prevent closer engagement. This is likely to be further off the lands than you would seat your conventional bullets and is a common characteristic with copper projectiles.

Many shooters have reported groups in the 0.2’s and 0.3’s (m.o.a.) with OEP bullets seated within this range. Should your magazine dictate seating bullets further off the lands, this is quite OK, but closer to the lands may increase pressure 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. Both bands should engage the case neck.

The importance of barrel twist.

All OEP bullets are precision matched to a specific minimum barrel twist rate. This recommendation is labelled on the box. Using the correct bullet for the rifle will produce the best results. Use of a barrel with a slower than recommended twist rate may not achieve adequate stability, reducing BC and accuracy.

Expansion.

OEP Hunting bullets are designed to expand and deliver devastating terminal performance at velocities as low as 1,800 fps, depending on target resistance. 

Primers.

Use the same primers you normally load with. Use of magnum primers is not required unless recommended for a particular cartridge. Match grade primers are highly recommended.

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. 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.®
