I have the BLR in 30-06 caliber. I did compare it against a 308 someone brought down to the range one day and the 30-06 looked like Fort Knox next to it. Just a lot beefier in the receiver.
Taken a couple of bear with it. Had an aimpoint and a Leupold 1x4 shotgun scope on it. They both worked fine. The gun as a whole is OK but for some reason it is my least favorite. Can't get it wet because major work involved in getting the wood off. I don't recall the Marlin lever action I had being any easier either though. I don't know what I was thinking other than it was an excuse to replace the Marlin I had sold and my buddies all brought lever actions to the cabin for a spare gun during deer hunting.
I always used it at my gun clubs "Running Deer Shoot" and it never failed to get all my allowed shots off whereas some of the semi auto and occasional bolts had problems but my guess is they were dirty.
Just don't get it wet or plan on a elaborate tear down. I think I even had to drift a pin out on the forearm somewhere. I don't remember other than my notes tell me only do a complete tear down on it every five years to polish and oil the metal under the wood.
Don't get me started on the tearing down the rack and pinion lever system. Took about 3-4 hours to put that nightmare back together.
If I could find fiberglass stock and forearm for it I'd like the BLR more. I keep watching and looking but no one makes one yet. I'd just degrease or WD40 the heck out of it after it got wet and hang it above the wood stove.
