Unlike popular belief, a longer barrel will cause higher muzzle velocity but not better accuracy. But higher muzzle velocity also means flatter trajectory so you will have benefits for long range shooting.

The thickness of the barrel however will increase accuracy by making the barrel more rigid and therefore reduce the barrel vibration during firing. Another benefit of a thicker barrel is that it has more matter to absorb the heat heat and more surface to dissipate it. A quality free-floated match barrel will not "deform" as it heats up because it have been stress relieved at the factory. But you still don't want it to heat up too much otherwise it will greatly shorten its life.

This is a very nice piece you have there. Great rifle for accurate long range shots.

True, that's what I meant to say when I wrote 'accuracy at long distance'. Thanks for adding the extra details about the flatter trajectory that I forgot to add.

Any gun will overheat if you keep firing round like crazy and it sure isn't the reason why I got that barrel in the first time, but for the vibration like you mentioned.

Hey BTW, let us know how it groups!!

I sure will when I get to the range.
I got a set of 20 bullets to test:
5x bullets of 64.0, 64.5, 65.0 and 65.5 grains to test.

But so far, at the store testing room using purchased bullets, I did 3 shots in the same hole and 1 two inches away due to the stress.
