There have been standards for this application for a very long time.
Although I have some feelings on what projectile I would use, I don't differ with the minimums set forth by the law. This minimum has been working well for 1000's of buffalo for a very long time now. For me to second guess that level of success and experience would be silly.
The 375HH with a 300 grain premium softpoint is the industry standard for minimum levels. Anything bigger is better yet, if it can be shot well.
I think that stepping up from a plain cup and core softpoint to the premium level puts you well ahead of the minimum requirement of the law. Even though the cartridge may be the legal minimum, the bullets today far exceed the function of what was used when these minimums were set.
Choosing a 270 grain TSX bullet at 2800fps for Buffalo is also just as acceptable in my opinion. This Bullet really packs a whallop and penetrates like magic. I'm leaning towards the speed benifit of 300fps over the 30 grains of weight by choosing the 270 rather then the 300grain bullets. That is for the TSX design only. If the bonded core bullets are your choice for buffalo, then the 300 grain bullets at 2550-2600fps would be the ticket.
