Polymer coated bullets?

I don't understand why anyone only offers .356 diameter 9 mm projos. They don't work in a number of guns, .355 works in almost any 9 mm.

Isn't it a 1000th bigger because it's cast? I thought I read somewhere, that cast will be bigger then jacketed so as to give it a better seal?

Got a lot of their boxes in my basement, they can be used for a lot of things. Using the ACME bullets now for several oyears. Now inly for .38 spl and .45. Used a lot of their 124 RN for mm, but several years ago there was an issue with the sizing and I had some problems. They made good very fast and easy, sent me a return label for the left over bullets and replaced them with .38 spl ones for me. I still buy a lot of these in 38n spl and 45, they are great.
For 9 mm, I am now using only Precision Delta 124 JHP

I have used Precision Delta's, very consistent projectiles. I used to use alot of zero bullets but the quality IMO
has dropped some in recent years.

I don't understand why anyone only offers .356 diameter 9 mm projos. They don't work in a number of guns, .355 works in almost any 9 mm.

I don't think anyone offers a .356 in a Jacketed bullet, only cast, plated or coated?

That's my understanding

I had problems with .356 plated, but not .355 plated. It's been a while since I used lead cast, and they were .356, but never had problems with those. Certain guns work fine with .356 slugs, some don't.

I suppose it all depends on how much over or under each barrel is to the nominal?
In reality, those of us that reload should be slugging our barrels anyway lol...
