Anyone using this in the 300blk? How is it working for you?

I'm using the NOE HTC310-225-RN-CE4 in 300 blackout. I'm shooting these at about 1050 fps and they shoot great! I'm using Alliant 2400 and I have a 300 blackout buffer spring from Brownells. Rifle functions perfectly. I have had the following issues:
1) My bore slugs at .308 and I size to .309 - any bigger and I get feeding issues.
2) I modified a magazine to cut down the front lip a little and smooth out the metal. I was getting lead shavings from the boolit hitting the magazine lip and it would cause the rounds to not fully enter battery and get stuck.
3) I found some powder coat to be too thick and causes the rounds to not go into battery/get stuck.

With #3, I have some HiTec coating bought a little while back. I have a feeling this will be the way I make these boolits from now on, but I need to do a sample batch and make sure that everything works according to plan.

EDIT: It's called the taco mold:
