Yep, duds will be fuds or whateverAfter looking at my Hornady app, the 143/147's and 130's are within 50 fps of each other after 500, but the heavies don't pass the lighters up within the expansion window. Both hit 1800 fps between around 800-850 yards depending on muzzle velocities. For me that's plenty of range for hunting - unless you're wanting more "wallop" factor or wanting to push out to 1000 yards (which I am not ready to do).
My daughter has hammered a lot of aoudad and mule deer @ and over 500 with 130 TMK. Zero issues.agreed but not sure if you'd want to be shooting game much past 500 with a 6.5 CM. At least that's been my experience
