IMO, they expand way too well! While these aerodynamical hunting bullets fly great, and improved flight over very long distances. I have come over the years to really not like them. This all comes from self butchering and seeing the severely destructive results they cause. This one even lists "Dramatic expansion" and I used SST's and if they hit the shoulder they ruined all meat with in a 3" diameter or so. I have thrown complete shoulders out in the woods for the critters to reclaim from the destruction and the loss of bullet weight I was not sure how much lead dust could be in the meat. Put it through the ribs and it is fine, but touch much muscle and your ruining a lot of meat. I also seen a lot more people complaining of this with straight wall cartridges being allowed in shotgun counties. Guys using 350 Legend and getting the same destruction if they hit a shoulder.
I went back to soft point bullets before switching to cast. I had deer DRT and run 60 yards with Core-lokts and had the same results with SST's. Just the latter really destroyed a few shoulders. Just my opinion from my experiences.
