MD, thanks for the explanation. I'm not sure if it was directed at me or not though. I understand the reason behind the design. I just don't care for how destructive the few I've seen have been. I've used factory Fed premiums in my .257 Bob years ago and they made a complete mess of things if a shoulder was hit. My boss back then always used 150's out of his .30-06 and had the same results. I just wondered if there was a general velocity to keep below so the soft front end wouldn't be so destructive. I hunt very thick woods and don't always have the option of waiting for a double lung shot and staying away from the shoulder.
Thanks
