Moly coated bullets in Swedish mauser?

My LGS got a pile of Federal ammo in 6.5 swede. I bought a box the other day & then realized they are moly coated bullets. I haven't shot them as I've heard all kinds of things about moly & have no personal experince.

In an old Swedish mauser, with a bore that has some rough spots, would it be wise of me to let these collect dust on the shelf?

I can load my own, so I do not 'need' these.
 
Why don't you consider some barrel lapping compound to sand out those rough spots? Try this: wrap a patch around a bore brush, coat with 220 grit valve lapping compound, and start stroking for about 100 strokes (50 back-and-forth motions). Clean it out, then finish with JB bore paste, 30-40 strokes
 
Moly coated bullets have fallen out of favor, but I still use them for some loads, because I am too lazy to redo all my load data.

It has been a while, but from memory, moly coated bullets will have a slightly lower pressure for a given powder charge that the same non-coated bullet, but I have never heard of anything negative* or risky about their use.

What have you heard that makes you not want to shoot them?

*on edit: aside from adding another possible source of inconsistency that could hurt accuracy
 
I haven't considered bore lapping. I don't know anything about it but for face value, scrubbing valve lapping compound down my bore doesn't sound like a good idea. It might make it smoother but how much material would it remove from the bore?

Pushing a very tight patch down the bore it feels smooth, however looking down the barrel from the muzzle end there's what looks to be rough spots. Also near the end of the muzzle the edges of the lands have copper on them I can't scrub out for the life of me.

From what I've read about moly, if you can't get every bit of fouling out of your barrel, the moly coating will cover it making future cleanings even harder.

That's just what I've read. I might not be grasping the matter fully & is why I'm asking. In a rifle with a slick & clean mirror bore I've heard they're fine. In an older rifle with a bore that's seen better days, not so much.

The rifle in question I have trouble getting less the a 2" group, consistantly, so I've been thinking about a new Shillen here lately anyways.
