If you mean is the live round likely to go off, I can't see how with no firing mechanism in the bolt. If you do much action testing, it would be a good idea to make up some dummy rounds ("reloads" without primer or powder) for that purpose so you don't need to strip the bolt for safety.
It shouldn't, but for me as a CYA I do stuff like that in the basement with the muzzle pointed at the poured concrete floor/wall. If it does fire, then at least nothing is going to make it outside the house.
No, as soon as you load a round in a gun it immediately fires. That is why you should NEVER load a live round in a firearm. In fact, just storing ammo in the vicinity of a firearm can make it go off spontaneously.
Seriously though, you're safe. I'm not sure from your original post if you know the difference btween a bullet and a cartridge. Reloading can be dangerous if you aren't meticulous about attention to detail, read up on the topic and find a mentor to teach you the basics...
Southern: You are correct in removing the firing pin to use the headspace gauges. That lets you feel the bolt close on the guage without the spring pressure.
Best to take Keenan's advice on the dummy rounds. If you use your dies they will be the same size as your live rounds.
ISC I do know the difference between a bullet and a cartridge. For some reason when I made the post, the knowledge I had on that particular subject flew out the window (A brain fart if you will)
See my issue is I am not a reloader so I have no access to dummy rounds. As far as pictures Mcgowen messed up the barrel they were making me so it will be next week when HOPEFULLY my new one is done and then a pictures I will post.
It's safe to load any cartridge in any rifle so long as the four cardinal rules of firearms safety are observed and so long as the firearm operates properly.
I agree, longrifles, but those are two big IFs. I don't use live rounds in the shot to test feeding; even if an AD did no harm to anything else, my ears would take a beating.
