Ok thank you for your input. Right now I am trying different manufacturer ammo 50 and 55 grain. My thoughts are either Benchmark(out of stock online) IMR4198, H335, CFE 223, or A-2460 for powder. Bullets I was thinking Hornaday V-Max or Varmint. Primers either Winchester W209 short rifle or CCI 400 short rifle. Again, thank you all for your input. Have a great day!
