Huh?

What is 'Best 18'?

LR55

You'd think someone, at some point in time, would have been looking for the Best 18" barrel in a subforum called "6.5 Grendel Build-It-Yourself & Custom Builds".

At least, I figured someone else would have.

[PVBoom]

No, they ask about best barrels. Then here, as anywhere else, it becomes "best barrel for what?" time.

[StevieP]

Precision Hunting rifle. Not a bull barrel. Not a pencil barrel. Better than average "stock" barrel at a reasonable price point.

Midlength (?) gas system.

Stainless steel or good quality 4150 w/ nitride or other quality finish.

1:8 twist or faster (1.7? 1.75?)

< MOA more often than > MOA, with good factory ammo e.g. Hornady SST or ELDM. repeatable (not a fluke) .5 MOA would be really nice but budget may not allow quite that level of custom match-grade quality.

grab a criterion, they have them on thier site, and on brownells @ 300 or so

Shilen's 18" mid tactical barrel is six groove, one in nine twist.

What bullet weights is 1:9 best suited for?

Stevie...this thread includes comment from Mr. Alexander himself regarding twist rates. Short answer; he liked something tighter than 1:9 for 18" barrels. https://www.65grendel.com/forum/showthre...twist-rate

The 1:9 twist is a common twist for .264 cartridges like the 264 Winchester Magnum prior to current trend of using long sleek bullets with high BC for long range shooting. I have two 1:9 twist 6.5 Grendel barrels and they are both accurate with bullets from 85 grains to 125 grains. My Son in Law has a 22” Lothar Walther 6.5 CSS with 1:9 twist which is accurate with 129 grain SST ammo. Supposedly the longer barrels do a little better with the slower twist.


Berger has a stability twist calculator which is useful for determining if your twist is suitable for a particular bullet. If your goal is to shoot long range especially with bullets over 123 grains the 1:9 twist barrel is not optimal. I’ve shot my 20” 1:9 twist Shilen barrel to 1000 yards with 123 grain bullets and am satisfied with it’s performance.

Looks like I do indeed want the 1:8 twist after all. Thanks.

No 8 twist is standard what you want is a 7.5 twist with 5r rifling
