The projectiles have been developed with a cannelure to allow seating to the correct depth for one of the following calibres. .223 Rem, .243 Win, 6.5 Creedmoor, .270 Win or .308 Win.
The cannelure is machined into the projectile to allow a light crimp to be put into the case mouth as the last loading operation. Our own trials have shown this to be beneficial for consistency when using copper projectiles.
The following projectiles have been used in the following cases during testing without issue:
- .223 - .223 Rem, 222 Rem, 5.56 Nato
- 6.5mm - 6.5 CR, 6.5 x 47 Lapua, 6.5 x 55.
- .270 - 270 Win
- .308 - 308 Win
The LPHP project has run a long and thorough testing programme from ballistic lab to field testing and with many steps in between. Gel blocks and deceased animals have been used to analyse expansion and penetration properties and once satisfied we moved onto extensive field testing.
Forestry Commission staff have used the projectiles in a professional capacity, reports have been submitted and improvements made accordingly. They have mainly shot this projectile in 308win. Other deer managers and Estates have then been involved in trialling .243, 6.5 and .270.
At product launch over 3000 deer have been shot in testing and evaluation. Shot animals have been butchered and assessed for meat damage alongside lead core shot animals to examine the differences and similarities between the two. Expansion envelopes found in laboratory simulations have been confirmed in field observations.
We are confident that we have produced a projectile that behaves in a way that stalkers in the UK will understand.
Ballistic coefficients have been derived from both labs and field data with data being collected from 0 to 300 metres.
The below are not recommended loads but information that we have used in securing proof data. Use safe loading principles and start at lower powder charge weights and work up to your required load.
