I grew up using a milsurp 6.5X52mm Carcano. I purchased a Steyr Pro Hunter in .30-06 Springfield a while back when I decided to resume game hunting after a long hiatus. I had numerous missed feed and attempted double feed issues with the Steyr Pro Hunter, and I came to the conclusion this push feed system is simply not for me. Subsequently, I've purchased rifles using commercial FN Mauser actions, and Zastava M70 design bolt action rifles. I have not had any feed nor extraction problems with these rifles, they suit me well. I agree with @mark-hunter that Zastava for example advertising these bolt action designs as "X+1" magazine capacity in these fixed magazine designs doesn't help matters. Having a "+1" cartridge was never important to me growing up, with the Mannlicher style clip used in the 6.5X52mm Carcano carbine. Outside of a combat situation, I really don't understand a real desire for a "+1" cartridge capacity in general for a bolt action rifle. My perspective is a detachable magazine is a much better design feature / modification to achieve a "+1" carrying capacity than a push feed system. If a single shot rifle suffices as a minimum for hunting non-dangerous game, and a double rifle suffices at a minimum for hunting dangerous game, I don't see any point for a "+1" cartridge capacity in a bolt action rifle used for hunting. Just my perspective.
