I have an elk permit for Colorado and need some input on a couple of bullets I'm trying out. I will be using my 50 cal Thompson Center Hawken. In the past, (over 20 years ago), I used the 370gr maxi ball to harvest two elk. I would like to avoid having to use the lubed bullets if I can find a bullet that will hold up to shooting an elk. The two bullets that I have found that shoot very accurate in my rifle are the Hornady 290gr bore driver and the Powerbelt Platinum 338gr. I shot them over the chronograph and the Hornady was 1650 fps. The Platinum was 1570. Has anyone used either of those two bullets on elk? I would like to hear your thoughts.
