I live in New Zealand and am just getting my first long range rig up and running.I shoot a .25/06 and currently using 115 gr Nosler ballistic tips at 3030fps. I shoot mainly feral goats which weight between 60 and 150lb, average weight would be around 70-90lbs. The problem I am having with the Ballistic tips is that they are not expanding quickly enough. I selected them because of their good B.C. A friend of mine is using a .243 with 75 gr varmint bullets and is getting good knockdown butpoor penetration and often has to give a finishing shot. I don't think it would be wise to go with varmint bullets but mine seem to drill right through unless I happen to hit bone. The goats we hunt are pretty tough and sure hang on to life. Any suggestions? Also what would be the maximum effective range with the .25/06 on such animals. Thank you all you guys at Long Range Hunting I have learnt so much reading all the posts that I have hardly had to ask questions.
