Magic 21 3/4"

[SamuraiTrapper]

I have a Savage 12FV in .223 that I was planning on cutting the barrel down to 20". I asked on another forum and it was suggested I go with the "magic 21 3/4" barrel lenght. Has anybody heard of this? What are your opinions on this matter? Here is a link to the story if you have not heard about it.

It is a myth. There is no "magic" length. Weight, contour, bore size, bedding, etc, all change any vibrations in a barrel.

If there was a magic length, all rifles would come in that length.

Thats kinda what I was thinking too. Too many variables to nail EVERY rifle down to one barrel length. Just wondering if anyone had done this.

Vibration pattern changes are probably the reason different powders shoot better in different guns. The burning rate changes the pressure curve and so on. Barrel length affects velocity most of all, actually the shorter the barrel the stiffer it is and more accurate. A 20" barrel should be great for a 223, if you look through some of the AR discussions you can learn about 223 velocities in shorter barrels because of the debates about 16" vs 20" barrel lengths common in AR 15 rifles.

I would think that if the magic length was 21 3/4 then my encore barrel would be that lentgh, but it's 24 inch.
