If I can get away with a 20'' barrel and save the weight from a 26'' I would love it, but I don't know if this would hold up. There are a lot of 20'' .308s out there, but do they lose velocity. I am more interested in what a .260 would do. If anyone has experience with this please let me know. Thanks.
Any rifle with a 26" barrel will gain velocity over one with a 20" barrel ! It's just a matter of
how much. With any cartrige there is an optimum barrel length where the percentage of
velocity increase drops off, and the gain may not be worth the other issues.
If you plan to carry the rifle to a shooting position and shoot long distances only, then I would
recommend a 28"+. But if it is to be used as a Carry rifle and used in an enclosure (Blind) I would
recomend 22 to 24" max. the loss in velocity will be minimal.
The 308 based cartriges perform well with 20 to 22 " barrels but 24" will do a little more and still not be cumbersome.
Just my opinion
