1.1.1 Slightly rebated/stepped as a result of hand swaging type tooling in appearance;
1.1.2 More accurate than a standard conical boat-tail? Find out for yourself;
1.2 Flat Base
1.2.1 Maximises accuracy at ranges less than 500y.
2. Shank/Bearing Surface
2.1 Sufficient length to ensure projectile alignment in barrel;
3.1 Moderately aggressive 12S calibre minimum radius ogives with a tangent finish;
3.2 Provides good velocity efficiency with good tolerance for seating depth;
3.3 Provides a significant portion of the overall projectile drag.
4.1 Designed to provide a consistent diameter finish with a moderately small open tip diameter, this should minimise the requirement for tipping/pointing the meplat.
4.2 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.
4.2.1 A meplat diameter of 20% provides the same drag as a meplat diameter of 10%, Figure 1 (Sommer 1952, 13) ;
4.2.2 An absolute pointed cone provides the most efficient meplat but has yet to be achieved with an open tip match (OTM) projectile design!
5.1 Precision gilding metal target jackets 95% copper, 5% zinc.
6.1 99.9+% extruded lead.
