Between a couple of buddies and myself we have killed 35 or so with ShockWaves with no problems when hit properly...With all bullets if I don't want to track or the deer is near thick, nasty stuff, I take a high shoulder and drop them...ShockWaves do this very well...

That being said, I have switched to the .429 Hornady XTPs in 300 gr just to try something else...My gun likes them and they seem to be working as well...As mentioned, bought in bulk it's also cheaper...

I've got a box of the 240s I picked up on sale last year, should get to them in a couple of years...
