That's impressive velocity, and one big fooking bear!Here's a hammer for you guys with 7 RMs. I developed this as a hunting load with 180 VLDs. It runs right up there with some of the bigger 7's without the extreme powder consumption associated with the bigger cases. I wouldn't recommend running anything smaller than 180s with this load. You might get by with 168s, but it really shines with the heavies. Load details below.
