FMJ yaw and upset performance

[Tony Williams]

Tony, I should've asked this earlier. I know that on your website you show some photoshopped pics of possible 6.5, 6.8 and 7mm cartridges. Does item 1 above mean that you've settled on 6.5mm? Are you planning to create one or more "wildcat" cartridges to do load development and terminal effectiveness tests? If so, do you intend to have custom bullets made for you?

I have always had a preference for 6.5mm since I think this provides more advantages over 7.62mm than 6.8mm or 7mm would, in terms of weight, trajectory and recoil. Provided of course, that the performance requirements can be met.

However, someone who knows more about bullet design than I do has expressed a view that there could be problems in designing a lead-free 6.5mm bullet of 120-125 grains with the required ballistic coefficient (.500+), since it would be very long, maybe creating stabilisation issues. It might therefore be necessary to drop the BC somewhat, in which case a larger calibre might better suited: it would keep the same overall length but with a lower LD ratio. So I'm keeping my options open.

There are no firm plans yet over developing a round, but confidential discussions are ongoing...
