Barrel length in .270 Win. Caliber
 

I noticed that both Remington and Ruger rifles chambered in .270 Winchester (among others) have a 22" barrel. Why 22" and not a 24"? Does this have something to do with the twist rate for the caliber?
Thanks.

Great link in regard to barrel info. Saves alot of talking, just point to the site and bingo you got it all. I think I will be bookmarking that one.

The burning rate of a powder can make some difference. A slow burning powder may burn a little better in a bit longer barrel. Most Manufactures put 22 inch barrels on the 270. However, give a choice, I will take a 24 inch barrel every time.

I dont know if Remington makes any 270 now except a Mod 7 with less than a 24 inch barrel.

Remington made a 700 adl with a 20" barrel. It now commands a premium on the used market.

I'll live with 22" easily.

No, it doesn't. Barrel length is not in any way related to twist rate. But length IS related tobore volume for the gas to expand intobefore exiting to the atmosphere.

The .270 benefits from a 24" tube vs a 22", in that the majority of the powder charge in that bbllengthis used pushing the bullet instead of providing you with an impressive muzzle flash! However, I once owned two 270 carbines with 20" barrels, which lost a good 75 FPS vs a 22" barrel, giving me no more than 2800 FPS with 150-grain bullets. Muzzle blast was "noticeable', but they still were quite accurate and killed things very effectively too.

I also think the .270 Win. would benefit from a 24" bbl.
