How Long Does a Rifle Barrel Last?

A cheaper barrel might last 2500-3000 rounds where a higher end barrel might go 4000+ rounds before crapping out, which often correlates to the original cost of the barrel.

Do stainless barrels last longer?

Stainless is more accurate because you can machine it to closer tolerances than a chrome-moly barrel. No, it won’t last longer than chrome-moly. I’ve had bolt gun barrels that shot out faster then c-m barrels. The stainless barrels on an average will loose their accuracy about 7-800rds sooner than c-m barrels.

Is stainless barrel more accurate?

Over 90% of high-grade match barrels are made from Stainless Steel. That said, chrome-moly barrels can be just as accurate, when made correctly, and there is evidence a chrome-moly barrel will hold its accuracy longer than a stainless barrel.

Which is better stainless steel or blued barrel?

Stainless is more corrosion resistant and usually stronger than blued steel. Stainless wont fingerprint and you don’t need a ton of oil on it.

How is a free floating barrel more accurate?

A free floating barrel will ring the same every time. So, the bullet should follow the same trajectory with every shot (all else being equal, atmospheric conditions, powder load and type, bullet size and shape…). A barrel fixed to the forearm of the stock can change the tone of that ring.

Why do you want a free-floating barrel?

A free-floating barrel is one where the barrel and stock are designed to not touch at any point along the barrel’s length. This minimizes the variance in possible mechanical pressure distortions of the barrel alignment, and allows vibration to occur at the natural frequency consistently and uniform shot-by-shot.

What is the advantage of a heavy barrel?

When your mission is to empty an ammo can into a poodle pasture before noon, a heavy barrel makes sense. It counters the warping effect of heat and helps you steady the rifle to hit small, distant targets. Logic tells you thick-walled barrels vibrate less violently during bullet passage than light barrels.

Is a free-floating barrel worth it?

Though free float handguards can be a little on the pricey side, the cost is well worth it. Apart from this, free float handguards can often be a bit heavier than their drop-in counterparts. Advantages of free float types include increased stability and hence accuracy, tactical flexibility and overall aesthetic.

Does a heavy barrel increase accuracy?

Heavy barrels are more accurate because the extra weight reduces recoil. Heavy barrels have a third effect that will inherently increase the accuracy of the rifle (and the shooter), and that is less recoil and less muzzle jump.

Is a bull barrel more accurate?

Bull barrels are more rigid making them more accurate (not as much flex). A shorter barrel is more accurate than a long barrel of the same diameter all things considered. That’s why when the barrels start getting longer they start getting thicker.

Why is a longer barrels more accurate?

The short answer: Yes, a longer gun barrel improves accuracy. Theoretical accuracy of handguns and rifles is driven by rifling, barrel length, and bullet mass. Therefore, a longer barrel increases the exit velocity of the bullet and the effective range of the bullet. Friction limits the allowable barrel length.

Is there a difference between 300 blackout and 300 AAC Blackout?

This is a question I’ve been asked a lot recently. Chaz, a commenter on TTAG, asked it this way: The 300 Whisper and 300 Blackout have small differences in their brass dimensions: Blackout 0.004 larger in the neck, 0.018 longer case length and 0.16 longer OAL. 300 AAC Blackout round, and got a fairly quick response…

How much does a 300 Blackout drop at 100 yards?

The bullet drops about 4 inches at 100 yards, 2.5 feet at 200 yards, 8 feet at 300 yards, 18 feet at 400 yards, and 30 feet at 500 yards.

What is the maximum effective range of a 300 blackout?

460 meters

What barrel length is best for 300 blackout?

9″ barrel
