Just ordered a new barrel for my ML. It's a perc .50 Hawken. I've never had one before but have shot a few. I bought this used and just ordered a new barrel. It should be here in a few days and I'm curious what I should do when I get it.
Shoot it out of the box?
Shoot a few caps then a ball? (it's a 1:66 round ball barrel)
Lube/oil/butter anything?
I simply don't know where to start. And...no I'm not an idiot that bought a gun on a whim, lol. I have a ML friend that is helping me with it. I just wanted some other opinions.
