147 Ms have never posed an issue for me in killing, however, I have a ton more experience with 143 Xs and 129 SSTs going back over a decade.
I’ve been pretty vocal and consistent for years on here favoring SSTs and ELDXs over the Ms for killing, once you get below the 6.5mm. Just my personal observations. I recall most favoring Ms and questioning why I favored Xs and SSTs.
I think folks are getting a bit wrapped around the axle with this. Ms are still good bullets that kill well (I have seen personal issues with 108s, 88s, and 80s but they’ve still always led to dead animals).
Unfortunately, lately, the factory loaded offerings and bullets lot to lot from Hornady have been frustrating to say the least. This is not just Ms, this is the Xs and SSTs as well. Being nearly out of old lot numbers that were fantastic I’ve had to go back to the drawing board a bit this year.
156 and 115 Bergers have been incredibly consistent from accuracy and in flight performance, and have been good killers this year, but it’s still fairly low volume to make strong claims (around two dozen kills between myself and
@huntnful). And he and I both tend to place shots with a high degree of killing potential.
Always happy to see more good killing bullet options. I’d love to mess around with the 6.5 and below options if they become attainable. Maybe even throw some 7mm through the 7SAUM but that will likely be complete overkill on animals.
