Ive used both the 139 Scenar and the 147 eld from 6.5 creedmoor and 6.5 saums. The Scenar is a tougher bullet then the eld but I’ve yet to grenade one and have used them in deer, elk, bears and coyotes without issue.
Most guys blowing the Eld up likely have throats or bores that are rougher then a cob in my experience as well as some indication that land count and diameter may have some effect.
