MP9 threaded barrel shooting high.

[ryu_sekai]

Just got a new threaded barrel and took it out yesterday. The weapon is dead on at 0-10 yards but from about 15-25 it shoots high. When shooting at 20 yards I have to place my sights just below a 4 in clay peigon to hit it. (clay on top of sights 6' O clock hold)

Anyone else have this issue when getting new bbl? Any way to fix it?

What ammo are you using? The M&P 9 is known to shoot high using 147 gr. ammo.
