Has anyone gone to a 21 3/4" barrel for accuracy?

I read a pretty long article about what the guys were doing in the Houston warehouse back in the day, and they opined that the absolute best barrel length for accuracy is 21 3/4". My Savage 308 has a little weird spot in the grooves right at the end of the barrel so I was thinking about cutting it back & re-crowning it, and of course it got me thinking about this number. So, has anyone tsted this theory for themselves?

I read the article, it seems very subjective to say the least that 21.75" would be ideal as a blanket statement.

Not to call into question the conclusions of great minds like Virgil King and Bob Fisher, but barrel length is but a small part of the overall equation. While I agree that a 21.75" barrel may be an excellent (hell...maybe even optimal) balance of length/weight/harmonics/etc., unless you are a world-class, benchrest-caliber shooter that is taking every possible measure to extract the utmost accuracy from a rifle from points A through ZZZ and everywhere in between, it isn't going to make a statistically significant difference in terms of the accuracy/performance of a stock, factory Savage barrel what length you cut it to!

Cut it back to 21.75" or 20" or 18" or any fractional measure your heart desires along the way and shoot it.

With a heavy contour barrel at 21 ¾ should give you the <span style="font-weight: bold">antinode</span> you desire thus you have reached your objective. If one used a VB like on a Remington factory 700 P model I would go a little shorter but what the heck would I know

I,m not good at linking. The Houston Warehouse article is a 'Must Read" however. Google; Secrets of the Houston Warehouse. These guys are talking about .035 MOA as being average grouping.

Barrel length in an of itself,plays no role in accuracy. Especially in no conditions conditions. I have a bunch of 21's due to balance and handling.

Interesting, although I too would be curious as to why such a specific barrel length would affect accuracy. Did they use the same load throughout? If so they might have just found the accuracy node for that particular round/rifle combo.

I'll have to look it up when I get home and give it a read.

If you're trying to tune a vibration node, it should vary based on diameter, material, profile, caliber, fluting, etc., so saying one length is optimal for everyone seems a little optimistic.

It makes sense that this length <span style="text-decoration: underline">may</span> be "optimal" for these conditions, however not necessarily so for other barrel profiles.

With that though, you certainly have nothing to lose by shortening it to 21.75".

Tune the ammo for the barrel length, 21.75" as a "magic number" is snake oil.

I have a 21.85" 6.5Creedmoor that shoots really really well. A friend has a 22" and it shoots just as well with his hand loads.

Another friend has a 1/4 MOA 6x47 Lapua that has a 26" barrel on it... again, tune the load for the barrel length and you'll get great results.
