but the guys I saw hitting that mark was with 53gr pellets. I couldn't find anyone (not saying that there isn't) that was getting more than 69fpe with a 43gr. pellet. I searched a few forums but couldn't find much info on guys doing high power tunes on their marauders.
I've posted pics on here before but here's another shot of it - I did add a grab rail under the forearm but it's not in the pics.
