Luckier then most.
I'd like to see a picture of the bore in a 243 Winchester barrel that has had 10k rounds shot out of it. Most 243 caliber barrels are toast after 2000 - 2500 rounds. I'm lucky to get 3000 rounds out of my 6.5 Creedmoor or 260 Remington barrel's.
My big burner is my 22 Creedmoor, the barrel last for 800 - 1200 rounds before accuracy falls off.

^^^What type of velocity would a 22 Creedmoore reach, assuming commonly used weights of 22 caliber bullets?
I saw similar velocities with my 22CM using 77gr Nosler CC and Sierra MKs.
Montana is smaller then Texas we only get 3200fps with a 200 gr in a 8mmrem mag.
I believe heavier barrels are also stiffer and more accurate on average. What's more, they are somewhat easier to hold steady and have less recoil.
That said I was recently reading that a hunting length sporter barrel can be as stiff as a heavy longer target barrel where competitors are trying to sqeeze out every fps. Im not sure on the 'formula' though to compare barrel length and contour for 'stiffness'
If you take a dremel and cut off wheel make a small shallow cut in the bottom of the but and use a chisle and light hammer.
Also when I took my 7mm-08 LWH barrel off I went with an X-Caliber 7.62x39 and after shooting it today for the first time since I started the build about 5yrs ago I couldn't be happier.
