Re: not long range but worth a look
Congrats oh the kills, good shooting! Iíve also found BTís to be fragile at high velocity so I avoid using them in areas where a close shot is likely. Without proper penetration, it would be easy to lose an animal with a nasty wound. The BTís are colour coded by caliber; yellow=.277, green=.308,ectÖ Federal also loads the 130 grain Partition and the 130 TSX for the .270 WSM, perhaps one of those would best suit your needs.
Best of luck,
