Went to a gun show in Knoxville today. Found a mag or my p238- check. Now on to my desire to reload 223 in my 1 in 7 AR. Asking for help from the vendors, I am told:

A. Under 200 yards your AR will be just as effective with 55 grain bullets than the heavier. You'll need a longer barrel than your 16" past 200 anyway.

And

B. I had suggested to me a military powder-( 844) to reload 75 gr. bthp.
(I bought one pound)
1. Does that powder burn too fast or the weight?
2. What can 75 gr. bthp be used effectively for?

C. $50 for a 380 mag- ouch!
