Only weak point on the push-feed I’m aware of is the bolt-handle attachment, the same as all the Classics. Not common apparently, but it happens. If I were getting one for hard use or dangerous game, I’d get it spot-welded. For general use, meh.
I’ll always take a commercial 98 over an M70, all other parts being equal, but the various Zastavas can be a crapshoot when it comes to finish; try before you buy. Never had a commercial, factory tapped 98 with crookedy holes, but some early FNs didn’t come drilled, and like sporterized ones, weren’t always worked on by the best smiths. I have a Heym with the lone rear hole just barely out of line, and rather than put a bunch of money into having it fixed, I’m using “alternative sights”. No way to tell if it’s a factory job or was done later as Heyms of that era are poorly documented.
I don’t obsess over cartridge choice, although naturally I prefer ones I’m already set up for. Both rounds in question are excellent.
