I ordered a 18 inch tactical to shoot suppressed and liked it so much I decided to do a custom build bolt gun. I chose a 20 bs 22 inch barrel as I am going to shoot it suppressed. Do you loose that much FPS by doing that?
I will try to post a pdf that Hornady put out when they introduced the 6 Arc, at the bottom is a chart of MV vs barrel length, for the 108-110 bullets.
