I just got done cutting up my cow elk. I used my lyman .50 to get her. I put her down at 238 yds(Lasar range) with a 300 grain powerbelt aerotip. I have took mule deer with the same gun, no problem. I do know is there is alot of different bullets out there for the .50. Knowing the gun is the best way to fill the freezer. Bench time with different bullets is where its at.
