Lots of good rifles out there. Almost all of the bigger bores (375 H&H and up) need a bit of work to feed and function flawlessly. Not sure why that is, but it's been my experience with 4 of them including a stainless M70 Classic in 416 Rem Magnum. Maybe just bad luck on my part, but after a bit of work by awesome gunsmiths they have all been great. Below a link to the article by Ganyana on the the Zimbabwe PH exam and a pic of my CZ 550 in 500 Jeffery which has had the AHR #1 Upgrade (3 pos m70 type safety, single stage match trigger (which is amazing) and straighten and fill bolt handle).
