Randy....Randy....Randy....why do you continue to head down this dangerous road.
You are quite likely right about Shockey using different bullets and in fact, I've never heard him say that he has killed "everything" with a Nosler. The only statement that I recall is that he killed all of the critters in his North American slam with the Nosler/Pyro combination. Shockey has killed countless other animals and some of these may have, like you say, died at the hand of a Barnes or Knight bullet. What does it really matter anyhow. Why do you have this perversion with calling Shockey down in public? I don't recall him making any public statements about you or your vocation.
As for the jacketed bullets, once you have enough kills to your credit to come to the table and talk about bullet performance, then we can talk. For now, velocity is the biggest limiting factor of lead bullets in sabots. They can't handle it. For sub 2,000fps shooters they likely work but after that accuracy is a disaster. (Remember, you brought this up)
I liked it better when we were getting along but I guess that doesn't do much to get a new messageboard forum up and rolling does it? Okay, you knew I'd take the bait and I did but there must be something else we can discuss besides these tired old subjects. But, I guess if you keep putting them on the hook, I'll keep biting. It's just my nature.
