I hope some one here jumps up and provides one of those cut in half bullet photos of the 115 gr 25 cal BT. I have used 115gr nosler partitions in my 25-06 successfully for moose and elk, but have been a bit gunshy with the BTs.
In my 7WSM 140 BTs are too frangible for my liking, but I have found the 120 BTs are a much tougher bullet...thicker jacket than the 140 in comparison to their length. I am not sure if the 25 cal has the thinner jacket. If the jacket is as thick as the 120 gr 7mm BTs, I would give them a try.
