Whats the story on brass or gold colored fmj bullets vs standard orange copper colored bullets?

Fiocchi 73 gr fmj .32 acp is "gold" colored.

Increased wear concerns?
 
Not sure if one is copper one is brass. Some like Swiss-made 9x19 Ruag Ammotec has copper color but attracts magnet like Russian-made stuff. I have only shot about 1500 rounds of Swiss stuff w/o visible problems, but that is not a significant amount. I have not come across fmj ammo from Italy where bullet jacket attracts a magnet.
 
Just a different alloy. IIRC (and I'm not an expert) the brass ones are a little harder.
But rifles often come with steel-jacketed bullets, most commonly in calibers and from manufacturers expecting full military lifespans.
If you can afford to wear out a barrel with even steel-jacketed bullets in your lifetime, you can afford to buy a new barrel.
 
The jacket is probably 70:30 cartridge brass instead of 95:5 gilding metal.
Probably less expensive if you have the equipment to draw the stronger alloy.
No problem, it isn't going to wear out your barrel.
 
Slight correction: the brass (yellow) bullets are usually 85/15 alloy not 70/30, a minor difference. They are very slightly browner, but essentially it's the alloy difference. They shoot just the same as gilding metal jackets.

You know, they are "precious metal" bullets. :D

I have been shooting Montana "Gold" and Remington "Golden" Saber FMJ/JHP bullets for decades. As others already posted, it's similar copper alloy that's a bit harder and some match shooters thought "brass colored golden" bullets may lead to quicker barrel wear (match shooters shoot several tens of thousands of rounds a year) but that concern went away long ago when apparent accuracy degradation from barrel wear did not show.

Some people even reshape 9mm brass cases to make 40S&W bullets and reshape 40S&W brass cases to make 45ACP bullets. ;)

Since many factory barrels like Glocks and M&P have surface hardening, no worries.

S&B 9mm has the same gold-colored brass alloy jacket. I've never worried about it slightly harder make up; figure if I can afford to "shoot out" a 9mm barrel with it, then I can probably afford to replace it when I do. :D
 
Never thought about this until the other day. Been shooting Fiocci 32 ACP, 73 grain - and then got some Geco 32 ACP and the jacket is much darker and more copper colored like a penny and yea, the Fiocci is yellow like the brass case.
