Are chromoly barrels good?
There are many people who argue that chrome lined barrels are less accurate than an otherwise identical steel barrel. All things being equal, this is true, but for most shooters, the degree to which accuracy is lost by using a chrome-lined barrel is generally unnoticeable.
Which is better chrome moly or stainless steel barrel?
CM is stronger, harder, weares better, but stainless steel is stronger, has a longer barrel life, corrosive resistant. It may have a better harmonics too. it’s not corrosion resistant, but neither is 416 SS that’s commonly used in making barrels. The harmonics has to be delt with in any barrel individually, CM or SS.
Is a stainless steel barrel more accurate?
Over 90% of high-grade match barrels are made from Stainless Steel. Stainless is easier to machine because it is slightly softer. 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.
What is the best material for an AR 15 barrel?
Some manufacturers prefer to use 4140 or 4150 steel while others prefer to use 416 SS or 416R steel for its properties. Some other manufacturers prefer to chrome-line the inside of their AR barrels and some do not.
Is a stainless rifle barrel better?
Stainless resists throat erosion longer so the barrel will have a longer life. The rifling also holds up similarly longer and stainless barrels will maintain ther accuracy for longer. Stainless an rust but it is much more resistant to rust than bluing.
What is the advantage of a stainless steel barrel?
Stainless-steel barrels have been around since the 1930s. However, they have recently seen widespread use for two reasons: First, their resistance to heat erosion is superior to chrome-moly barrels; second, their resistance to rust nearly eliminates corrosion in humid environments.
Do stainless steel rifle barrels last longer?
I should go stainless, right? Generally speaking, 416-R stainless steel is a better choice for shooter requiring peak accuracy from their barrels. 416-R stainless has reduced barrel life compared to 4150, but will stay more accurate over its usable life.
Is stainless steel good for gun barrels?
Generally speaking, 416-R stainless steel is a better choice for shooter requiring peak accuracy from their barrels. The machining properties of stainless allow it to take a better cut during machining, creating higher-definition rifling, crowns, and chambers.
Which is better stainless steel or chrome moly barrel?
In terms of barrel life and accuracy, we can find no difference comparing clean barrels. I have read that stainless became the norm on match rifles because it’s something that wears out and needs to be replaced. Stainless doesnt need to be coated and chrome moly does to prevent rust.
How does Moly extend the life of a barrel?
Their strong belief is that moly helps to prolong the accurate life of the barrels. A few tests were made to find out if the wax was necessary and if thickness had any influence. This was only tested with respect to pressure and velocity, no accuracy testing. Moly alone seem to give 60-65% of full effect.
How does Moly affect the accuracy of a bullet?
Sized cases would not be the same. Typically moly takes down the extraction force with 50%. One explanation of the increased accuracy could be that moly helps the bullet align in the bore. Thus, bullets with long bearing surfaces would not gain much from that help. Pistol bullets in 9 mm has been coated with no effect on accuracy.
How long does a Norma Moly bullet last?
These Norma test photos show wear after 10,000 shots with Norma Diamond Line “Bana”, after 3,700 shots with uncoated bullets, and after 7,000 shots with Diamond Line Fält. Compare the results for yourself. Norma claims “testing showed barrels retained accuracy more than twice as long when Norma moly bullets were used from the outset.
