Part 4 338 bulletsI tested the 300gr Berger OTM, 300gr Sierra Match King, 285gr Hornady BTHP, 265gr Barnes LRX and the 250gr Nosler Partition Gold (they no longer make these, where moly coated and have longer shanks than current partitions). I will test the remaining 250gr Sierra Match King and the 250gr Hornady BTHP along with some 6.5 bullets later this fall.
