Glad you made your hunt, maybe I will make it out in your hunt area some day. Congrats on a very nice goat. And great eating. Best I have had is soup made with it.
Take a look at my avitar bull bison 125 yds 45-70 Buffalo Bore load 405 gr flt nose 2000 muzzle one shot took top of heart off, bullet aginst hide opposite side .
I would have to say 22 LR, 30-06 and 375 HH. That would cover all game on most of the world. Guys only 3 rifles not hand guns, also covers all 2 legs or 4.
I shoot a Marlin heavy ss fluted barrel 1" all day long at 100 yards . We used to put a golf ball at 100 yds and shoot where ever it went as fast as the next shooter could get on it to keep it going.
If you don't reload try Buffalo Bore , look at my avatar 2500 lb. buff , one shot 405 gr. sm/jacked, bullet aginst hide other side, 3 steps down. White tails 325 Hornady one and down. 2000 muzzle flp's on BB load, 2200 on Hornady.
