6.5 grendel - fact from fiction

[JASmith]

...You'll probably loose around 100-150 fps per every 2 inches that you shorten your barrel...

The velocity loss is likely not that strong.

Try using the chart (nomogram) at http://www.65grendel.com/forum/showthrea...d-Velocity --

Also, don't forget that one can easily see plus or minus 50 ft/sec going from one rifle to another while using the same load -- so a difference of a couple of inches tends to wash out.
