Thanks for the responses!

I initially asked this question because I bought a Glock 19 upper with a threaded barrel that had a honeycomb compressor on it. It did not like my 115gr titegroup loads at all and my 124gr were not totally reliable either. Factory 124gr worked good.

Southwest precision arms was revamping their comp, and their first version got good reviews so I preordered their new comp. it came this week and I got to do some ammunition testing through it. It ate everything I fed it! Both my hand loads and factory. I have a bunch of titegroup so I think I will finish it up and then I do want to experiment with a few of these powders listed above.

I appreciate everyone input into this thread!
