According to my sources, the 348 gr. Powerbelt Aerotip is the most popular elk bullet out here. Locally, there are a bunch of folks who swear by the 385 gr. Buffalo bullet. One of the local gunshop owners has a cigar box full of expanded slugs that came from elk harvested with this bullet. I have used the 410 Hornady Great Plains with very good results - and will go back to it if the 338 gr. platinum powerbelts don't work out. Lots of choices . . . . .
