I set one up in .308 for a friend. He won it at raffle. He wanted a 1.75x6 Leupold on it. I used Warne bases and rings. Nice set up. Really great wood on it. They are a rack and pinion system very similar to the BLR's. It's a smooth working action but more complicated than other designs. It really liked Core Loct 165's IIRC. Shot sub 1" no trouble. I emailed Henry a few times in regards to offering it in 358 or 338 Federal. They replied that larger bore chamberings for it were in the plans; further, IIRC, they stated that they were looking into 35 rem or 356 offering for their other lever style. So, I plan to pick one up, but I'm waiting for a big bore option. With the trend going smaller these days, I might be waiting a long time.
