Looks like a little round I call a 270 AX. Except its based on a 300 Dakota instead of the 7mm Dakota.
Its a great round, basically the same performance as a 270 STW but with shorter OAL which works better in some standard length magazine boxes.
Only drawback is bullet selection. Berger needs to get that 170 gr out!!! Matrix bullets would be a great choice for this velocity range as well.
you guys are making me think ".270"!
awesome looking case!
