What do you get when you cut a 6.5 Creedmoor-chambered barrel down to just over 16 inches?

A XP100 in 6.5 IHMSA?

I’ve been eyeballing a 16″ 6.5 Creedmoor bolt gun and had some reservations about velocity loss. This article and the included links have convinced me to go for it. Thanks for all the work you put into it.

Thank you for these articles. Some of the comments seem a bit unappreciative of your efforts. Again THANKS

For the comment about barrel break-in: I don’t see how this can be a major issue. If I can count, only 120 rounds were fired for the test. There shouldn’t be such a change in speed that it would nullify the observations made.

If he were trying to shoot 500 rounds on a new barrel, and didn’t take speed changes into consideration, it would be a different story.

the creedmore is a good varmint gun but the 6.5 Remington mag is a true elk and deer killer .I have knocked a 800lb elk off it’s foot at 600yards and it never got up .I seen a man in Utah shoot a mule deer at 300 yards with the 6.5 creedmore that a 140 grams bullet and he hasn’t found it yet I seen it go down he hit it in the front shoulder. 6.5 creedmore is a good varmint gun but the mag is a true hunting rifle.

I don’t like leaving speed on the table.So I would leave the barrel longer.

Grimstod,

I didn’t “fail to do proper barrel break in”, I shot a new barrel. In fact, I have the only data set on how barrel break in effects MV I am aware of anywhere, https://rifleshooter.com/2017/07/a-look-at-how-rifle-barrels-speed-up-measuring-the-increase-in-muzzle-velocity-in-new-barrels/

If you’d like to share your data sets we can compare…

Till you boys get the science settled I will stick with the old .308.
Short of a .300WM/.338 it is the most proven round on earth.
With AlCO,Barnes,Sierra and Nosler bullets from 110 to 220 grains I have a solution for any problem.

Barrel break in all is truly a myth. Some of the world’s greatest barrel makers have said in their years of experience it is not needed. They have found no true variance in longevity or accuracy. The first several round clean out any milling and begin to add copper to the barrel. I don’t get this sudden urge with a proper barrel break in.
