Barrel life 800-1100 rounds!

[SKWERLZ]

No they don't, pick the appropriate caliber for the task at hand.

^^^^^^

Solution: 224 Valkyrie.

22 Creed is going ridiculously fast for such a lightweight bullet. 22 Creed is for rich kids with more money than sense.

Or 22arc

As always:
Barrel life is HIGHLY dependent upon rate of fire.

Or 22arc

Im a big fan of 6 ARC. Got 2 of them, in semi.

Dont know much abt 22 ARC... other than I already have the .224 caliber covered.

22ARC is pretty good as are my friends 6 arcs.

In a bolt gun?


Only Jerry Miculek is fast enough to burn out a bolt gun in 1000 rounds. rofl

I guess if a guy did a little load development and then spent the rest of his time shooting 950 coyotes, he would have it for a while.

Best response winner.

Well done sir.

Absolutely

In the heyday of sage rats I took 22-250, Swift, and .204 Ruger. Plus a 10-22 in case I ran out of highpower. I rarely used the 22rf on a trip. Barrel life was not a consideration, parting shot and air time is what it's all about.

This was in March and sometimes early April, we usually had snow showers while shooting so part of the mix is barrels cooled much faster and while we all usually wore insulated coveralls there were plenty of coffee breaks to warm up, shoot the shit, and watch the feeders get full between rounds of shooting.

The heat index of the powders used is critical for helping barrel life on a high volume shooting.

AA2700 is one of the coolest burning powders on the Heat Index Chart and has a burn rate close to 4350.

H335 trippled my barrel life in the 6 BR vs H322 on p. dog towns, multiple barrels proved this. Win 748 extended the barrel life in the 223's over H322 shooting 50/55g bullets. AA1630 extended the barrel life in the small cases, 17 AH and 221 Fireball.

The 6 BR is simply amazing in the barrel life with H335 with Rem 7 1/2 primers, 5000 rounds minimum if you start with a zero freebore reamer. I am shooting 55-68g bullets with the H335.

Us older guys had to learn years ago not to load top-end pressures with ball powders, just back off 1.0-1.5g for the heat, and all will be well.

I have not seen the Heat Index of Stabal Match and 6.5, and I bet the powder will be in the cooler end of the spectrum.

Years ago, it was common to shoot 600 rounds per day EACH on a slow day, and 1200 Rounds EACH on a good day on the P. dog towns. On the hay fields infested with ground squirrels, you could shoot all day and never move the truck.

We cooled our barrels by running water down the bore, followed by 4 dry patches, dry the chamber, and then back to shooting. Lots of BS out there saying this method will harm barrels, and we learned to shoot 30" unturned blanks so we could set the barrels back up to 4 times.

223 bolt guns cleaned every 300 rounds when using H335
" 125 rounds when using H322/AA2015

6 PPC cleaned every 300 rounds when using a fast lot of H335-2230S-60s@3550
6 BR cleaned every 300 rounds when using H335,55-68g
243 AI cleaned every 150 rounds when using AA2700 with 70s at 3850

We measured the muzzle dia with graduated reamer pilots on a grizzly rod, .0002 increments. The setback was determined at a point to where the bore diameter was equal to the muzzle diameter, so you can duplicate new bore dia at the throat. This method is extremely effective in achieving new barrel or close to new barrel accuracy. Few realize that the bore dia grows in width and length.

We learned that IMR 4064, IMR 4895, Varget, and N550 eats barrels like you are shooting battery acid, so much so, that the barrel could not be set back due to 9" of the barrel being severely worn.

I'm pretty sure aa2700 is Win 760.

Which is the best 22250 powder on the planet.

 

[wright brothers]

The barrel salesman are raising and stocking these PDs you know.
A great conspiracy cover up unleashed lol.

 

[urbanrifleman]

Or 22arc

Someone please explain the 22 arc in a bolt gun. I don't see it.

Per Hodgdon aa2700 is definitely not 760, asked and answered. I pointed out some load data was exactly the same, they came back and reiterated their statement, not the same, slight differences. They wouldn't elaborate further. It came up due to some GRT workup that someone was doing and Hodgdon didn't want people assuming they were the same.

side note: aa2700 and 40gr bullet = 4500+fps in a Swift, fun times

Why does someone need to explain it?
Are there rules against it?

 

[GetReal]

Absolutely

I think you.mean "velocity of projectile," and NOT "rate of fire"

No human that has ever lived could get a bolt actions rate of fire up to that of a semi or full auto whose barrels last 3 to 5000 rounds.

Think about it... you could shoot probably 50 to 100,000 rounds out of a 22 Rimfire even with copper washed bullets because the velocity of the projectile is so slow. Even at a full auto rate of fire at 1000 rounds per minute.

E.g. rate of fire equals 800 to 1000 rounds per minute ( only possible in a semi or full auto gun)

Velocity of projectile equals 2600 to 3,400 ft per second ( possible in most any gun).

 

[SKWERLZ]

I have friends that shoot 7 RUM and 338 cheytac improved.

Both absolutely smoke barrels but shoot incredibly flat.

Forget it. I’m done.

 

[ebb]

Don't think of it as a 22 ARC think of it as a 22PPC improved.

 

[GetReal]

Good. Thank you.
