Enjoying the Knowledge Base?
Has Nathan helped you via an email response?

We are a family run business based out of Taranaki, New Zealand. We specialise in cartridge research and a number of various shooting related services. We have put a great deal of effort into helping hunters, we have helped police here and abroad with forensics cases and have also been involved in terror threat research for the EU.

The bulk of our research is offered freely with income derived from book sales, bedding kits and donations. Tutorial hunts and custom rifle work also provide income but at this time, we have a limited capacity for these services due to time restrictions.

Please understand that Nathan donates a minimum 1500 hours per year personally helping shooters worldwide, whether by email, via the forums or by phone. Its no easy task, requiring a great deal of patience and dedication. On top of this is the time taken to create the knowledge base, involving a great deal of ongoing financial investment into rifle and cartridge research. It is also important to understand that our bedding kits are priced at break even prices as a service to shooters so we are very much reliant on donations and book sales for personal income and further research.

If you find the resources on this site to be valuable we would be sincerely grateful if you would help us to continue our research by making a donation by completing the form below.

Whether you choose to donate just one dollar, or whether you can afford a little more, we would be very grateful. This money is utilized to put food on our table on a week to week basis and to fund ongoing research. It does make a difference and again, we are immensely grateful for each donation.
