So I bought some sample packs of the eggleston bullets.

I got 115gr 9mm but they are .357 instead of .355. Being that they are polymer coated lead, do you think they will be an issue?

That's a good question. I'd try it with starting loads and see, then you could tell US!

Ask the mfg. There could be issues shooting them out of a Glock, also. They use polygonal rifling, and the bullet does not grip the same as a jacketed bullet.

If they're sold as being 9mm, then they ought a be fine in a 9...and 115 grain is a 9mm weight.

They address the sizing difference in the FAQ on their website and they address the Glock question too.

Well I did have problems with the 40sw bullets. Used 180gr .401. about every third to fifth round would hang up trying to chamber. I will try the 9mm and see what happens. They are cheap at least.

After looking at their site I had the idea that you might need to run your taper crimp die just a little bit harder. That mighta helped on your .40 loads...maybe.

Just load up some dummy rounds and plunk test. If they don't headspace and chamber correctly, it's probably not worth trying.

On Youtube, look up a plunk test video from Danny in Kerrville. In addition to talking about what the test is used for, I try to make some .358 bullets work In my 9mm.
