Today was the first day i got to take the Mountaineer to the range. Gordy asked me to shoot it with the red plastic jacket plug first. I also want to mention this new plug is also BH209 compatible.
I took the Leupold Ultimate Slam off my LRH Elite and put it on the Mountaineer. This was the first three shots at the range with the Mountaineer at 100yds.
The next group was with 120grns of BH209 and a 300grn bullet. It really opened up so i dropped down to 110grns. What a big difference. The taped holes are with 120grns.
The weather was pretty bad out. The 250grn bullet shot so well i decided to shout a group at 200yds.
