How many grams weight for mm cartridge?

Thank you so much for all those responded - you guys are a great source of intelligent info! 
  
  I don't know much about cartridges as you must have guessed.
I bought the Denon TT used and the guy said the cartridge is Shure V type that is pretty old design. I don't have manufacturer's recommendation so I will just leave it at 1.7 grams then - it sounded better than .5 grams.

  

Would be nice to know the exact Shure model you have. Most of the V15 type series, (II, III or IV) track best around 1.25 and some of the replacement styli for these track best at 1.50 grams.

If it happens to be a V15 VxMR, then 1.7 would be just about right.

I think you are right - it is V15 type II, with small styli. I will use 1.25 as you suggested. Thank you madness!

I doubt that it still has the original stylus on it. I bet it’s been replaced. I would try 1.4 grams. That’s a good compromise.

If you don’t mind spending $50, order a stylus from Ed Saunders. I’m using one on my V15 Type III and it’s stellar. If you ever upgrade to a more expensive table and arm, keep the V15 II and buy a Jico neoSAS/R stylus for it. Now that’s heaven!
