First I like to say: Thank you everyone for the encouragement and advise.

I just got off the phone with AHR, American Hunting Rifles. I guess, these folks are CZ 550 experts. Beside building full custom rifles on the 550 action, they have a thriving business fixing the problems with factory new guns. The action can be smoothed and feed problems corrected for under $100 bucks. Based on the knowledgeable response on the phone and recommendations from this forum, I will probably have them fix the 458 feeding. They offer a very appealing package for $500. That includes a 3 position bolt safety, reshaping the bolt handle and install a new trigger. A full level 1 upgrade should correct any and all potential reliability issues. That is the claim. Opinions?

So for somewhere between 1100 and 1500 it appears, I can have a good to better 458 Lott. I guess the next good day over 40 degrees (F), I will test fire the Lott. Find out if both myself and the rifle can deliver the goods.

I mentioned (maybe not clearly) the 505 Gibbs has been returned to the factory. Depending how this comes back it may get the above mentioned package. The more I fondle the ammo, the more I have my heart set on a 505. I think at this point there is no turning back.

Thats where it stands for now.
