^ So your technique of cycling an open bolt machinegun on a live round is only half as stupid (in your mind), thereby making what you said okay?

Got it.

Firestarter,

Doing it slowly without allowing the bolt to fully seat the round, one time, to test a bullet's contact with the feed ramp isn't terribly unsafe if done pointing the gun down range (in a safe direction) with one round in the mag and finger off trigger. What's the worst thing that can happen? You shot one round at a target?! Whoop de doo!

The whole point of The example was you don't have to remove the magazine to test a single round on whether the firing pin will for certain ignite the round, as you suggested. You can cycle it and test it with the mag.

Warning to those reading this: if the bolt rests however gently on the round, it may go off at any time, even immediately (it would depend on how strong the main spring is, how sharp the firing pin is, and how strong the primer metal resists the pin under pressure). The point being that the safety ENGAGED on a live round with the bolt closed won't make it safe. It was just an illustration to explain mechanics of this aspect of the safety.

I didn't and don't suggest that anyone should attempt that, unlike fire marshal bob who vehemently defends and in fact advocates using gasoline as a cleaner.

You're acting like children!

By the way Hey, I check my open bolt SMG by feeding Live rounds all the time. I just take the firing pin out. One of the advantages of that removable firing pin. ;)

Boy did this thread go WAY off topic. :(

Maybe childish, but WITTY! LOL
You won't see this (higher) level of humor on the typical lib site. Its obviously good natured and it can help add a touch of humor to an otherwise dry detailed topic.

Speaking of being on topic... LOL

Years ago when I used to shoot my semi OB .45 RPB, I used to use the widened slot rear "safety" position. But then I quit. Firstly it was way too much hassle as the spring pressure required a lot of dexterity to twist it in and out of the slot. You have to pull back slightly as you twist. That struck me as unsafe and an AD waiting to happen. It also occurred to me that it was putting a lot of unnecessary stress on the bolt handle at its weakest point and also making a dent in the front part of the slot.
What I'd REALLY like to know is just what that widened slot was for? I have several RPB guns in my collection and only a couple have it and it and they're both mid production; so hardly an added improvement that lasted. Anyone know for certain what the details were? Someone had to go through a lot of extra trouble to alter the stamping process, so there had to be a purpose.

Still off topic but I have to add, if you have a failure to fire / feed with an open bolt don't just quickly pull out the magazine to see what is wrong. I knew this and still did it one time. If you do make sure the gun is aimed in a direction it is ok to shoot in..........

FOR THOSE NEWER INTO OPEN BOLT or JUST WONDERING: Always re-cock the bolt, put on safe, then remove the magazine. If there's a fail to feed, if you remove the magazine it may clear the issue and then the bolt is free to fire...and it may fire on you.

I can't for the life of me teach my friend, a super experienced firearms guy, to quit trying to engage the bolt forward after cocking it...(another issue).
