Re: ar reloading advice please

68 or 69gr, possibly 75 or 77gr, probably not, my 1:9 16" loves 60gr Vmaxs over Varget.

Do you have a .223Rem, 5.56x45, or Wylde chamber?

Reardless book .223Rem loads should be ok, watch for pressure and work up.

Benchmark has given me good results with 55gr and lighter projectiles.
