I just found out that I got my Colorado elk permit and now it’s time to decide on the bullet to use. I’m shooting a Thompson Center 50 cal Hawken. I have been testing a few bullets and there are two that stand out accuracy wise. The Hornady bore driver 290 gr and power belt 338 gr platinum. Both shoot very well. I shot them over a chronograph and the bore driver was 1650 fps and platinum was 1570 fps. What bullet would you use for elk?
