'Pends on what you want to do with it. From what I've experienced and read, the Brownings- including the BLR- are good, accurate pieces. If you're looking for something to punch paper with, up to say, 300 meters, you're probably fine as-is.
If you want something you can drag through the mud and still have function, you probably don't want a lever gun.
If you want something that will allow you to dot the i in a magazine advertisement at 300 meters, you probably want a bolt gun.
Basically, if you just are looking to practice shooting at up to 300 yards or so, you're set, unless you're looking for "extreme" accuracy. Barrel length theoretically IS a factor in how accurate your piece is, but you have a trade-off: as you decrease your barrel length, you theoretically decrease "barrel whip" (vibration), increasing accuracy. At the same time, a longer barrel (up to a certain point) add velocity, increasing
practical accuracy. (In other words, since your bullet travels faster, it doesn't drop as much, and the shooter doesn't have to adjust as much at distance.)
Clear as mud?
