On my recent project of a .22LR pistol I have hit a dead end. Everything is done except for the plating and the barrel. I should receive the barrel blank tomorrow or the next and I am fully aware of how to set it up correctly in my lathe the turn and thread it but after that I will need to chamber the barrel which is where my problem starts. I'm going to need to buy the chamber reamer and I don't plan on starting the barrel without all the proper tools on hand (why set up the barrel in the machine twice) I have checked out Brownells and a few other online vendors and I'm coming up with a few types of reamers. Some are "Match" and others say "Bentz" but all are .22LR reamers. What should I be looking for to chamber a barrel on a .22LR semi auto pistol? I'm not looking to make this gun a super accurate target pistol, I'm just making a hobby outa this and hoping to learn some new things (but get it done right)
Next on my question list is the headspace. I know the specs of a .22 round....
Case type Rimmed, Straight
Bullet diameter .223 in (5.7 mm)
Neck diameter .225 in (5.7 mm)
Base diameter .225 in (5.7 mm)
Rim diameter .275 in (7.0 mm)
Rim thickness .040 in (1.0 mm)
Case length .590 in (15.0 mm)
Overall length .985 in (25.0 mm)
Rifling twist 1-16
The rim thickness is .040 wouldn't I want .040 to stick out behind the barrel. Also I can't find any specs stating how much headspace a .22lr requires so I assume that the headspace will be different for each gun. I have found headspace gauges but they say for bolt action rifles (wouldn't it be the same?)
Any info would be appreciated thanks. I'm sure I'll have more questions once I think about this a little more.
