25-06 is fine just use a good built like the Nosler trophy grade ammo in 100gr partition.
My wife hammed her oryx with 257wby with 80gr ttsx.. its chin left a hole in the ground it hit so hard
Know also the vitals are a lot more forward then a deer. Straight up the leg
She also had complete passtru on both shoulder bones.
Right, and a ttsx is not a partition, it's a monolithic, which aligns with what I said above.
Ok I'll give you that... Even 80 vs 100grains, but fowlerplayer dropped a big bull red stag with a 100gr partition.
I've dropped a big 600lb cow elk in the panhandle with a 25-06 100grain partition at over 300 yards, had a passtru on both shoulders also.
My favorite bullet in is the ttsx, but unfortantly you can get a decent OTC load for it in the 25-06 it's only load by federal and it's to light of a load, but the partition is the next best thing and a whole he'll of a better option then BT, SST, corlok, SG etc.
