A few months back I bought a .300 Weatherby Accumark (my first) and other then a couple sight in sessions, last Friday was my first time seriously trying to see how accurate it was. All I can say is I'm very impressed.
My best group came with factory 180 grain partitions. With this I got a 1/2 inch group. I haven't tried all the different factory loadings, nor have I reloaded for this rifle yet. But if this were I'm starting out, I'm very impressed. The rifle handled very well and I'm looking forward to the coming black bear season.
