.243: After a 100 BTSP (don't remember the make) blew up on a fairly large WT's shoulder over thirty years ago, I switched to 100 NP for deer and the problems went away. I see no reason to change.

.30-06: Also, I had a 180 Interlock ( Light Magnum loading) come apart on a mule deer when it struck heavy bone. A follow up shot ended the mess. I feel that one was a fluke, as I bought a twenty five year supply of those because my Mauser liked them. Unfortunately, I'm down to the last box or so. There have been no other problems with that lot.
