Really good couple of pieces on the Field Sports Britain Chanel last week - - so you can watch it.
First bit was on building Double Rifles and the Chapuis Factory.
2nd bit was on shooting foxes with Norma / Hornady ballisitc tip bullets in 223 / 22-250. They shot a number and then x-rayed and carried out post mortems to show the fragmentation effect of a ballistic tip bullet. I will avoid the incoming over using BT bullets on deer - my only comment is how far bullet fragments spread, but equally how a 55gn bullet is effectively completly stopped by a fox so not much chance of ricochet etc.
Both very intersting bits.
