I have been shooting the hammer mono bullets out of a ruger american predator 6.5cm with good accuracy and when they came out with the little 85gr. bullet I hesitated at first. But then I got a sample pack of 15, loaded up a ladder using varget at 43, 43.5, 44, and 44.5 gr. for shots into an inch at 75 yds the first day, adjusted the scope and the next day put 3 rounds into a 1/2" at 100 yds, using 44.5gr varget lapua lrp brass, cci200 primers. primer was starting to flatten but not terribly, brass was fine. fps I think is up around 3200-3300, the chrono went on the blink after the first round of the ladder though. gonna use them on whitetails this year.
