Function testing loads
 

All my parts are at the gunsmith (AR upper build), and I've sent him my 221 fireball GO and NOGO gauges, along with a variety of dummy rounds I've put together.

He is asking that I make up some "function test" loads for him to try in the upper, to make sure it works as intended. I am using a 3-position gas block from tp555, so I want to send him some subsonic loads, and some high power loads to try.

30 cal bullets I have on hand:

Sierra Match Kings 200, 190, 175, 168 & 155 gr
125 gr Nosler Ballistic Tips
125 gr Speer TNT hollow points

Planning on using CCI #41 primers, but I've got a variety of primers to choose from.

What should I load for him to test with?

Thanks!
