Barrel length isn't really a concern. You only lose about 100 fps per 2" less than the factory barrel test length.

Shorter barrels are actually more accurate than long barrels, in general.

This goes against the conventional wisdom, I know.

However, shorter barrels are more rigid than long barrels, and are less suseptable to "barrel whip" or the harmonics that harm accuracy.

This is a relatively new thing that people and gun manufactures are just starting to realize, but snipers and bench rest shooters have known for quite some time.

In general, a short action mated to a short barrel will be more accurate than a long action mated to a longer barrel. Rigidity is the key and shorter systems are more rigid.

Of course you can build a bench rest rig with a 30" barrel that will out shoot a short barrel rig but all things being equal the shorter rigisinherentlymore accurate.

I'm not trying to start a tangental argument so if you disagree you can just research it for yourself.
