I’ve shot bulls with both, and while the 300 mag is certainly more than adequate, there’s just something about my 338. I’m thinking it’s the frontal diameter buts that’s just me. The 338....it just stops em dead in their tracks....just stomps em. There is no question about what’s happening when the 338 impacts a bull at any of the ranges I’ve shot bulls at (48 - 351 yards).
That’s just my opinion...that’s all. I’ve never shot one with a Creedmor so I can’t compare. 😏 I’m hearing it’s better than a 50 cal.
All this assumes a good, lethal hit, of course. Gut shot is gut shot, no matter what caliber.
