The PSA upper looks good for a no frill upper.
If you look around a bit, others are out there.
But I went with the DSA no frill in SS. I'm on day 71 and waiting. But I would rather have it right than in a rush.
I think the hold up is the barrels with the tighter twists.
I keep seeing these gorgeous builds and start looking at what the parts run.... I think I will be happy with no frill for now.
The cost for store bought doesn't faze me. I haven't shot anything I didn't make at home for 30 years.
The brass for the 300 is standard .223/5.56 that is cut off a the shoulder and formed. The primers are the same as for the .223/5.56. The bullets I plan on using are what I run in my .308s/30.06s. The powder matches up to what I can use in loading .44 mags. This is a no brainer for me.
Next up is a tossup between a 6.8 and one of those big mambos, 450 or 50...
