Best video so far on the Tube. Thank you for taking the time to inform us.

Very informative video on the often misunderstood aspect of headspace. Thank you.

Outstanding video. Lot of great information with visualization.

Great visual aide and explanation!

Great Explanation!

Excellent!

Awesome visual 👍

学习了，确实不错👍

Damn good video.

hi mate . 40 mm for lathes spindle bore its good for barrel work or need 50 mm.

very good explantation. Thx. Question: if the barrel freebore prepared to 308 Berger 200.20X, how possible reload with Berger 230 gr Hybrid OTM tactical (30112) without reaming?

Very good video :) although I have a question. So I’m looking to make a barrel chambered in 22 hornet. I’m new to gun smithing but I do know how to rifle the barrel and a few other things. What I am kinda struggling with is how to chamber the 22 hornet. Since it’s a weird shape and only slightly tapers I’m wondering if the chamber has to be exact or if it can be a bit wider or maybe even just straight, the reason for this is cause chamber reamers for the 22 hornet where I live are very expensive and rare so I’m thinking about trying to chamber without one. I know if it’s wider the case will expand so can this be reversed by reshaping and trimming the case? I’m looking to reload the spent brass. Thank you :)

how hard does the bullet hit the lands? Example, what if you had a 9mm bullet at .355 inches, what would the land diameter be? Smaller .354 or bigger .356? And how about the bore? Must be a decent size bigger? What if the 9mm wasn't rifled, what would the bore be then, .356? Sorry, just started learning. I been searching for these specific answers but can't seem to find them.

If you were to rebarrel the .243 can it and other traditional chamberings be made with some freebore to accomodate longer bullets? Thanks for the video.

Hello sir! Can you tell me what is the interior size of AR-15 barrel before it was rifle by using rifling button?

If your barrel is eroding, and you have plenty of barrel to work with, why don't you cut the chamber deeper and cut the shoulder of the shank deeper as well to, in effect, have a new barrel? Especially if your barrel has no timing needs, you could cut a bull barrel a couple of times and save the cost of a barrel at least once, if not twice, in the life of the rifle! I have a rifle that would need an entire new barrel due to headspace if I did not cut the shoulder and chamber again, which would make the project too expensive due to the amount of work, if I had to add the cost of the barrel to the job. In my case, by removing the old barrel, cutting the shoulder back by one thread depth, and reaming the chamber, I will have solved a headspace problem, and the only cost is the labor of the machine work. And the rifle will have another 50 years of life in the family, plus, the barrel will remain original! But in your case, by cutting the shoulder and chamber, you get a fresh barrel, without the cost of the barrel, unless you have spare barrels laying around?

7 thou per 100 rounds??? Wow!!! Do you find that to be fairly common across many cartridge/calibers, or just the 6 CM??? Everyone has heard the stories about how the 6 CM has a short barrel life and eats up barrels compared to other cartridge combos.

Didnt you see that real gu smith chanel, the host, (i forgot hos name) daid that 6.5 creedmore had all types of factory ammo problems, at a time when everyone wanted one cause of the Bradley Cooper movie...
