I have had very good luck with the 50 grain v-maxs out of my 20 inch barreled ar.It is a wylde chamber with 1-8 twist. Around 24 grains H-322 with a Winchester small rifle primer is what works for me.
I get an email from Midsouth Shooters Supply today that they have Hornady bullets on sale. I found the 50 grainers for my 223 at 60 bucks for 500 pills. It is limited to stock on hand. I thought it was a good price.
The raffle is in Millhousen just south of Greensburg. Greensburg is are mailing address and so you can find us with gps. Fields is the gun dealer we get the guns thru and they are in Rushville.
