Design Characteristics

1. Base

1.1 Boat tails

- Slightly rebated/stepped as a result of hand swaging type tooling in appearance;

- More accurate than a plain boat-tail? Find out for yourself;

- Creates the appropriate amount of drag to keep the centre of pressure behind the centre of gravity;

- Maximises accuracy and velocity efficiency at 500y+;

- Critical to stability/accuracy during transonic and subsonic velocity levels; Depening on overall design the boat tail and mach speed, boat tails can contribute over 50% of total projectile drag!

- Angles used depend on the boat tail length but for long range (500y+) range from 10 degrees down to 7 degress.

1.2 Flat Bases

- Maximises accuracy at ranges less than 500y.

2. Shank/Bearing Surface

- Sufficient length to ensure projectile alignment in barrel;

- Tapers slightly from a maximum diameter at the Base to where it meets the Ogive.

- Surprisingly the shank contributes little to the overall drag through the atmosphere of a projectile.

3. Ogive

- A moderately aggressive 12+ calibre ogive with a tangent finish.

- Provides good velocity efficiency with good tolerance for seating depth.

- Provides a significant portion of the overall projectile drag.

4. Meplat

- Designed to provide a consistent diameter finish with a moderately small open tip diameter, this should minimise the requirement for tipping/pointing the meplat.

- Does provide a portion of the overall projectile drag. Most designs have an optimum meplat diameter of 15% of their projectile calibre at supersonic flight. A meplat diameter of 20% provides the same drag as a meplat diameter of 10%. An absolute pointed cone provides the most efficient meplat but has yet to be achieved with an open tip match (OTM) projectile design!

5. Jackets

- Precision gilding metal target jackets 95% copper, 5% zinc.

6. Cores

- 99.9+% extruded lead
