Im going to try this one more time as it looks off I came off the wrong way if its under warrenty call up cz and have them adress the issue or send it over to Ed Plummer American Hunting Rifles - CZ Owners and to my understanding on all of his rifles but one uses a cz action and if he can get a 600 overkill to feed in one he would get your 505 to feed.Seems they have alot of trouble with rough actions and feed ramps but also you will need to have both of those rifles bedded and cross bolted as many have stated they tend to split stocks
