Difference is most aren’t trying to do full mounts prairie dogs. Shot distances on the T10 are considerably closer as well (sub 50yds). There’s no need to spot impacts at that distance. I’ve missed a duiker at that distance and they didn’t even move. They seem to freeze compared to other animals thinking they’re hidden. With regards to the other hunts and species mentioned, I know multiple people who shoot does or deer hunt with their 375 regularly. In a calling situation like coyotes and bobcats that’s a different style of hunting than what most T10 are shot during. It’s also why on the dedicated T10 hunt I did I took a different gun since it was a different style of hunting a few species.
Like I said, I brought the .308 on a dedicated T10 hunt. I knew shot distances on certain species (the two mentioned) could be longer than average. I knew night hunting might happen. I knew I might be shooting moving game as well. I spoke with a professional ballistitian (from one of the major manufacturers) to get his opinion on bullets and calibers given what could be found (post covid). Thats what we settled on.
IMO the main issue with T10 isn’t the bullet doing excessive damage. It’s the bone fragmenting or exploding on impact. The T10 species have a much thinner skin. It’s almost paper like on some. Because of body size they don’t have the meat/muscle structure that helps catch and stop the bone fragments. I think this is what primarily leads to excessive damage and the explosive wound channels from even the smallest bone contact (ribs in the case of my Klipspringer). This seems to be more of an issue at the higher velocities other calibers named like 22-250, or .223 shoot at. A PH in Zim said he felt the 22 Hornet was too fast and did more damage than the 375 on the T10. A 375 at 2150 just punches through whereas a .223 is moving over a 1000 fps faster even with a 60gr partition or something compared to a 55 or 62gr FMJ. The .308 and bullet I used in my T10 hunt also shot a Kudu, multiple Bushbuck, and multiple Impala or Warthogs and had pencil like wounds regardless if it was on the shoulder, the neck, or behind the shoulder when culling for camp meat. If i was doing it again, I’d have shot the Klipspringer and Grysbok with the 375. I almost didn’t shoot the Cape Grysbok with the 308 after seeing what it did to the klipspringer but thought it might’ve been a fluke because of how delicate their skin is.
