Wow Rattus58,
Looks like these bullets could cause some major problems. My T/C Hawkin is an old one, 5 digit serial number, so I'm not sure what the twist rate is. I am going to take Adam's advise and call the T/C folks on monday to see what all they have to say about the rifle, bullets and loads. I sure appreciate your info and "heads-up".
I will of course share any additional info from T/C with all of you.
Meanwhile Rattus, take care.
Mahalo Nui Loa,
