Hugh, I live in an area of Alaska that has a wild bison hunting by drawing permit [130/year]. When friends from othet parts of AK draw a tag, They usually stay with me and I act as neighborhood guide as I know where teh bison usually hang out. I have three 375 H&Hs that are often used on these bison as well as moose and brown bear. I have used the Federal 300gr Sierra BT for 15 years with good success but they no longer load the 300 gr so two years ago I switched to Federal High Energy 300 gr Trophy Bonded Bear Claw ammo. I find this to be a more reliable all-around load and very accurate. I did have some Sierras seperate but still kill the animal. The TBs have all exited but with good internal rsults. These TBs will shoot through both shoulders of a large bull bison and break bone etc....I hope this helps....Vern
hd, I think Sierra bullets are just fine to target practice with or hunt thin skinned game if you will, but on an animal such as Cape Buffalo I would spend my money on a premium bullet that will in fact stay together and lessen the chance of bullet failure. Barnes X, Swift A Frames, Woodleighs and Monolithic solids.
If your talking American Bison "Buffalo" then you could no doubt use those bullets and they should do the job for you in that respect.
It only took the gun writers 20 years after the introduction of the Sierra .375"/300 spitzer boattail to note that it was a bit soft for dangerous critters like Cape buff. Also BT bullets shed their cores more easily.
I would follow the advice above to use premium bullets: Nosler Partition, Swift A-Frame, Winchester FailSafe, Federal's Trophy Bonded, Woodleighs, etc. I used the Swift last September to bag a buff in Zim, and I can recommend them.
