Yes please. I come to IV8888 for really nerdy technical details about guns and ammo.

Every time you fire a round, the cartridge is attempting to explode in your face, but the chamber prevents this from happening. As pressure builds after you have ignited the primer, the brass is stretching. Too much stretch (I.e. cartridge is undersized) and instead of using the pressure to send the projectile down the barrel, the pressure escapes by stretching the brass so far it breaks. Not good. On the other hand, too tight of a chamber doesn’t allow you to close the bolt. Not good. Headspace is the sweet spot that allows you to both close the bolt and safely fire the cartridge. Headspace in a nutshell.

swanie, very true. The forster field gauge is 70 thou. I just commented to Eric on this. The one the Brit armorers used is 74 thou. The chambers are were made deliberately longer on Lee Enfields. I reload more 303 than anything else. I really think it is important to check your LE rifles to see where they are at as far as headspace wear. Sort your brass to each rifle. If your full length sizing keep a good eye on it you will likely only get a few reloads with full length sizing

Nice job on that 303 explanation Chad. Got a lot from that. 👍🏻

"Go" gauges are important for idiot-proofing a firearm. If someone decides they're going to force a cartridge to fit, that can cause excessive chamber pressures.

Guys this is the best video y'all have made that I have watched. You explained Head Space and what it entails. Great Video

Chad's hair is in perfect head space.

As of now, I'm in the process of enrolling at SDI and I can't remember the last time I was just excited about something. Please keep doing what you guys do. I learn so much from you guys

The best way without a head space gauge to tell if your bolt action has issues is to just simply watch your fired brass casings. If you see the shells start to get marred (on the back where the brand name is) and shows extra shinny or flattened lettering. Is a good sign to go get your rifle checked for head spacing.

There are plenty of tips and tricks you can use to get around headspace issues in rimmed rifles, fireforming combined with the "O-Ring Trick" can preduce brass for a reloader that is safe to shoot all day long.

Excellent video and nice example caught on camera of excessive headspace. I've been laughed at but I always check my AR builds. I had one fail the no go. All new parts. The company I bought the barrel from did replace it (after some back and forth with customer service and sending the barrel back with bolt for their "guy" to check it). Anyway, great vid!

Newton's First Law: An object in motion will remain in motion unless acted upon by an external force. Newton's Second Law: Force equals mass times acceleration (F=MA) Newton's Third Law: For every action, there's an equal but (or and) opposite reaction. This last one is of great interest to us shooters...especially those who think that a handgun has "knockdown" power. Per Newt's 3rd, if your firing a gun with enough "knockdown" power to actually knockdown a man upon impact, then you too would be knocked down with each and every trigger pool. The fact the mere ounces on a pistol affect felt recoil should give you enough of a clue that there's no such thing as knockdown power when talking about pistol rounds. What we should be talking about is "fightstopping" power. Is there a difference between the common pistol rounds with respect to their ability to stop the aggressor with the same number of rounds. For example, does a .45 acp consistently stop aggressors with less rounds, equal rounds, or more rounds, than a 9mm? This is tough to quantify because of the myriad of factors affecting an aggressor's decision (both voluntary or involuntary) to cease their aggression.

In fairness to .303 enfields, other than the p14 fixing excessive headspace is as simple as buying a new bolt head, easier than most rifles

@6h471

2 жыл бұрын

The problem with that is that when you start measuring those bolt heads, you find that, they will vary as much as .005 in length for the same numbered head. Then you get into the relationship between the bolt head thread clocking vs the bolt head actually seating against the face of the bolt. You cannot have a situation where the threads are carrying the thrust load. It ain't just as simple as replacing the bolt head. A lot of these guns will happily close on a field gauge, even having very little use, which is totally unsafe. I have several examples of these rifles, and truthfully, I grew tired of dealing with their headspace issues long ago. They are an interesting historical artifact, but IMO, a wall hanger.

Excellent video - Thank you both!

Please do more firearms facts videos like this I had my facts wrong about what headspace actually was and this answers exactly what I needed to know thank you

All Finnish rifles were gauged before storage. If the rifle failed - it was dismantled and used as parts. The barrel went to smelter.

oh I can completely understand your hesitation at first, but I have been shooting for years now, and when I get a good point of reference (bench for instance) and working on muscle memory (holding the fire arm the same way every time) and astablishing the same firing position every time, I'm actually not a bad shot. Infact, if more people focused on muscle memory, astablishing the same grip and position every time, instead of relying on just sights, I think most people would see a vast improvement in their shooting...also, when ever I handle a fire arm, I am clearly communicating with those around so I know where everybody is, and I insist that anybody who hands me a gun, that it is unloaded with chamber open, so I can inspect and feel the gun myself, and I also keep that same rule when ever I hand off a gun to anybody else.

Eric wondering if your 303 field gauge is 70 thousands (forster) or 74 thousands. The Brits used a 74 t. versus the forster SAAMI gauge made at 70 thousands. It may not close on the 74. Love the videos on the old military rifles and the technical stuff too. Keep on doing what you guys do.

Chads hair going strong

Thanks for the upload

I've had quite a few AR barrels not headspace, but I've only ever had one that had excessive headspace, the rest were all way to tight and had to be reamed deeper or sent back to the manufacturer. I always run both a go and no-go gauge for that reason. On one LR308 barrel the bolt would not lock on a go gauge but would lock on Remington factory ammo, but not on Federal and some Winchester. So just save yourself the time and trouble and get the go gauge and use it.

Just getting into handloading, great video!

That was great and wery inform for me. Many thanks you

Thanks for the knowledge guys.

"You watch a youtube video on that?" Eric- "I made the KZread video on this" What a boss flex.. Lol

An object in motion tends to stay in motion unless acted upon buy an external force. Pascals law is more appropriate. Pressure is equally transmitted upon the walls of an enclosed system which the headspace area is. The more space that is open to this pressure makes it risk prone to failure.

Ever had a chance to read "Hatcher's Notebooks". He took an M1917 Enfield and reamed the chamber ever deeper as he test fired the gun. The only issues he had were insuring that the extractor held the bolt face closely enough to be set off by the firing pin.

In Michigan southern region deer hunting regs for pistol cartridge max length is 1.8. Discuss cutting 45/70 cartridge to 1.8 and reloading and used in 45/70 actions.

Great topic. Great video. Thanks!

@7:20 I think what you were looking for was every action has an equal and opposite reaction... so when fired the projectile goes forward pushing the cartridge back just as hard and fast!

The Mosin Nagant kinda does have a 3rd locking lug. Also, I've found out that rim lock isn't an issue because of the interrupter.

another thing even just with partial case head seperation/ rupture is that they can cause squibs by dropping the pressure so much that the bullet doesnt get pushed out thank god i looked in the chamber after getting the case out different to other squibs there is no unburned powder and there was a boom so you dont expect it maybe put the gun away and next time you are at the range you ruin it well i cleared most of the squibs i encountered with low pressure blank cartridges

What are your thoughts on tig welding the bolt face and then turning it to correct the head space?

You can try a never used System 98 and the bolt will have space without a round or headspace gauge in the chamber. It is stopped by the Extractor, if you remove it it has even more space.

What about checking headspace on the LMT MRP and MWS? Opinions? I don't swap bolts, they are paired with specific barrels.

Is there a way to posses a firearm and incase of a consfiscation on firearms can you keep it stored in anothe state? If you dont live there

no kidding... I was answering emails on one screen and looked up at the other screen an ALL I SAW WAS HAIR!!

Chad's hair = Hippie 😁

So got a Type I bolt for the 6mm Grendel instead of Type II? Going based off it is 6.5G brass and the headspace.

I've got an old remington model 8 (1922) and the primers are slightly backed out after firing all factory loads I've read this is a sign of excessive headspace is this correct

I'm shopping 6.5 Grendel barrels for a DMR type of build and about all I'm seeing is type 2. For that reason that's probably what I'm going to build and buy a barrel and bolt for. I'm wanting to buy a bolt carrier without the bolt so I can get a barrel and bolt together. I have not been finding bolt carriers without the bolt.

Good episode! got one on timing next?

Hi Eric, did you remove the extractor when using the field gauge in the bolt rifle? It doesn't look like you did. Thanks
