My question is, that with the quality spitzer-type bullets available, why would one use these pumpkins for anything? It has been proven many times that round-nosed bullets do not penetrate, nor kill any better than pointy ones.
It has also been proven that big and slow out penetrates light and fast if you are talking C&C type bullets. About every elk I have killed with those 'Punpkins" I have found the bullet under the hide on the far side. Regular BT spitzers, I usually find the core and bit of the jacket.
I don’t buy it. If they are coming apart, then you used weak spitzers. Bullets of like construction will perform similarly and also be very capable on long shots, if they are a spitzer design.
Use what you want, but the pumpkins belong in the tube-fed rifles.
