Hi Mike. I just mentioned the bolt action calibers as there are no new makers for them that I can see. With CZ closing their 550 line the 505 and 404 will go back into the history books. Ditto for the 416 Rigby with the loss of CZ and Ruger no longer making it in their No. 1 and Mark II models. I can't see ammo makers producing those calibers for much longer. I could be wrong of course and hope I am. Regardless, the focus of my original query was the health/longevity of the two DR calibers 470 and 450/400. I hope they're both around for many years as well, but I do have my doubts.Just wondering why you mention those bolt calibres ?...don't think issues with ammo for them...505 might be harder but it's being made ...the gunshop I use here has had delivery..500ne..505..470ne..500j..416 rigby..404...plus other ones ...450/400 there as well...
