308 Win Barrel Length
« on: November 05, 2011, 10:14:22 AM »
 Read an article on cutting down a barrel from 26" to 18" the results seem interesting.

I have 24", 20" and 16" barreled 308's.

I have had the 16" to 1k with no trouble. It was cool and the elevation was 2500ish. I'm not sure what it would do on a hot summer day at the same elevation.

I've shot this load, 175smk, 45gr varget, win brass, cci br2, through all three barrels on the same day.

24" = 2695fps
20" = 2648fps
16" = 2495fps

The 24" and 16" are chrome lined barrels. The 20" is a SS from Rock Creek.

I like the 16" for weight an portability and I'm confident it's adequate to 800yds.

18" would be a great compromise. I started to go there at one time. I decided, if the rifle was going to be used as a precision rifle, why not grab the extra velocity that the 20" offered.

I have a platform that allows me to swap from 16" to 20" in a matter of a minute or two.

I'm seriously considering the sale of my 24" bolt gun. I have to put some more time behind the 20" before I know for sure.

I had a Lawton .2980 tight bore 18" barrel that was only 40FPS Avg slower that my standard bore 24" barrel with the same loads.
If I where going to build another short barrel .308 I would build it with a tight bore barrel again.
As others have said shots at distance where not an issue.
