As for the little part, I assure you that I am quite a bit taller than your 5' 2" frame, although you have me well beat in the girth department.
Answer my questions, or run along back to the couch. Its the only play you have left.

Blah blah blah, ask around buddy ask around.
Wait a minute the whole 3 people in your life probably have never even seen a range.

Until you wanna step up and quite making excuses your nothing but white noise!

[Rman]

What exactly is it that you are asking me?
What BS?
Punctuation counts.
Blast curtains?
You want me to explain to you what principle? How a rifle works?
Are you one of Dick's "buddies" coming to the rescue from the couch?

Ask around about what?
Seen plenty of ranges. That's what happens when you actually go and shoot.
Speaking about people and lives, why is that you couch riders always feel the need to include all of your so called friends and acquaintances in your arguments? Can't handle reality on your own?

What excuses?

You still haven't answered any of my questions.

See you avoiding the issue at hand , dont have a clue who D284 is.
Blast curtain is the flexable membrain used to seal the main and coaxial guns to the turret .
And the principle of obturation if you please

What is the issue at hand?
Lucky you.
Seriously, what in the hell do main and coaxial guns have to do with a guy fire forming 243AI brass in a hunting rifle?
I can only guess that you want me to explain obturation to you, so you can tell me that as things get hotter, they tend to get bigger? I kinda have that covered, thanks.
If you want to ask me some specific questions, go ahead, and we can have a discussion about what I did, and what I saw, and what the outcome was.

Rman you are nuttier than squirrel poop.
If you'll excuse me, I have reloading to do, for a shoot this coming weekend.
My reloading chair is comfy, but it ain't no couch.

Ok your barrel has no cooling mechanism so how do you prevent round pre fire.
Obturation is what stops throat wear ie gasses being controlled by a good seal from the expelled round and expanded case . A rifle is a rifle 4.5mm-16" as heat expands the barrel the gasses pass round the projectile and the case, this creates pressures far above normal opperation. This is two issues care to share others you encountered.

The fact that all you can do is call me names, and run away, speaks volumes of your character.
The fact that you can't answer any of my questions speaks to your ignorance.
The fact that you demand that I drive for 3 hours to show you something that wouldn't have the first clue about, speaks to your arrogance.
The fact that you need to round up a bunch of fellas to meet me, speaks to your cowardice.

You're a real jem, fella.
Keep up the good work.

Time to end hostilities.

We all agree that shooting barrels till they are too hot too touch and pouring water on them just ain't smart.

The one thing I like about these threads is learning new words i.e. obturation.

Now, tell me how obturation stops throat wear? Obturation happens every time the trigger is pulled, as does throat wear. Yet you claim that obturation stops throat wear? If it did, then barrels would last forever. They don't.

Just ask me some questions, ok? I can't guess what it is that you want to know, or what it is that you are trying to prove.

Weird eh a word for how a chambered round works , who can answer how it works with out brass.

Funny the 16 " guns on the iowa class at 70 yrs old still work fine. Prevent perhaps is a better word .

I never claimed to know squat about the 16" guns on an Iowa class destroyer, mostly because I don't.
Prevent isn't a better word, because it doesn't do that either.
If it did, barrels would last forever. They don't.

Under proper care many rifles do last relatively forever miss use as you explain on the othrr hand ??? Are you under 20??? Iowa look it up.

Was that the whole point to all of your posts?
That under proper care, many rifles do last relatively forever? Wow!
I have many rifles, that under proper care, won't make the 2000 round mark. Go figure.

Thanks Tips!!!

I cant help that you buy junk. my family's .303:works great its 73 ish as are many other fully functional rifles over 100 yrs old . If you putting hundreds of rounds thru as fast as you can reload no wonder you get worn out rifles try a savage we have one it 35yrs old thousands or rounds still shoots great.

Don't read so well do you?
And really don't have a clue about what you're talking about, either.
Rifles that get shot, get worn out.

More whack a mole.

So how many rounds before this one showed signs of wear?

"I had a barrel set up specifically to fire form 243AI brass. I would run hundreds of rounds through it at time. We almost got a cigarette lit from the barrel, just in front of the chamber.
When put against the tire on the truck, it melted a groove in the rubber.
It was left to "cool" for about 10 minutes, and another 150 or so rounds went through as fast as magazines could be loaded and the trigger pulled. It were a two man job. We poured water on it to cool it down before it was put away. That barrel showed 0 signs of throat wear, and still grouped MOA at 2 and 300 yards.

Don't believe everything you read, as most of the info comes straight from the couch.

No rifles with hot loads and poor shooting and care practices get worn out . Rifles that are taken care of last a long long time. I have gunnery tickets I can assure you, I can prove I know what im talking abought just drive that hour north lol .

Even with proper care, and proper loads, throat erosion does occur with high powered rifles. With certain cartridges, like the RUMs , and the STWs , significant loss of accuracy can occur in under 1000 rounds. Within 1500 rounds, I have seen the accuracy go from sub1/2moa to well over moa.

Certainty these rounds push the limits of what can be achieved in case pressures. Basically hot loads even if designed for these rounds . If researched we imo will find poor obturation due to gasses partialy overtaking the round at energy transfer.
