While I agree they should, that hasnt been my experience. Theres always at least some ammo that will consistently get left in the chamber, and some thet gives no issues.
My 457 dosent like federal hunter match, or at least the brick i had....im on the last box,
One 597 didnt like the Aguila hi-velocity and took effort to chamber it, and usually left it in there. The other didnt seem ro have an issue with it....both shot the hunter match well.
My 795 so far eats everything, the buckmark is pretty good too, tho ill have to pick a case or two out any time i use bulk federal.
Had multiple issues with bulk packed winchester ammo, with having to knife them out of the gun being the least annoying.
Thats just been my personal experience, and I have seen fouling, and ware (my buckmark got a new extractor and spring about 5 years ago, it started drooping everything) cause the issue as well.
