700mm vs 600mm Xbarrels

[Redick]

Wondering what's the difference or benefits of the 700mm Xbarrel versus the 600mm?

Potentially more velocity

Roughly 4” in length, which will relate into possibly 10-15 fps more per inch of barrel length depending on reg pressure and hammer spring tension. They’re a law of diminishing returns at some point. But basically you should be able to create 40-60 fps more switching between those 2 barrels.

I was thinking of maybe trading a 700mm for a 600mm barrel to cut the length down. Thanks alot

Can someone indicate that maximum fps can give the 600mm .30 with power plenum and ammunition weight

I don't have a .30 in 600 but the 700 I got one to 910 with JSB 50 gr but they were much more accurate in around 860 so I did not try faster.
