The 140 6.5 and 130 270s I used all sucked. Huge shallow wounds with fragments everywhere.
I shot a 100 pound buck in the neck with the 260 and it failed to break the spine, blew a 3” hole in the side of his neck though.
Chest shots with no bones hit on small deer and pigs with the offside of the rib cage looking like it had #8 shot embedded in it. Hit a shoulder and pretty much write off eating it.
35 Rem and 30/30 factory loads have been good. Of course about anything resembling a bullet will work at those speeds but they have or had them figured out.
