BRL: what lever actions did the instructor say to bring?
? The BRL in 7-08 sounds like a lovely and finely made sporting rifle made for hunting, hunting accuracy and light weight for easy of carry. With all due respect to Browning rifles it does not sound like the rifle I would take to a practical shooting course that will burn through 600 rnds in two days. I think that is just a bit beyond the rifle. She may hold though - that is, the action may still function but it may also seize due to heat and the barrel may still shoot with accuracy but that would be a terrible thing to do to a BRL.
This is not to say that after a total of 600 rounds a BRL would not continue to function and shoot, but after 600 rounds over a period of just two days you are liable to put a serious hurt on that rifle.
I would ask what lever actions he was referring to.
I took a long barrelled AK to a Appleseed shoot and ran through almost 600 rounds over that weekend without any problems for either me or the rifle (except that my left arm was seriously 'sling warped' from using the sling as much and as forcefully as I did), but if your practical course is anything like the Appleseed shoots you may wish to think about using another rifle....... jmtcw.
