New on YouTube. Connecting two .30 caliber barrels, for a six foot long .308 barrel, MDT tests factory match ammo and then cuts down the barrel(s), progressively.
The gun’s velocity is never higher than at the longest length, it progressively decreases from near(ish) magnum velocity, and it actually shot well considering the bullet has to leave one barrel and enter a second.
This is remarkable in not only pulling off the junction, but also surprising the shooting public about the effect of extra barrel length. Too bad that gun is gone now!
