MP 2.0 Performance 5" 9mm OAL HELP!

[marathonrunner]

Hey Guys

I called Smith and Wesson Tech support to see if the 2.0 Performance had a match barrel, they told me it is exactly the same dimensions as the standard MP 2.0 compact.

I am using Bayou polymer coated 145gr FMJ and what is strange, the chamber seems shorter than many other pistol brands If I load the OAL, anything longer than a 1.075 will result with the bullet rubbing up against the lands and grooves, thus it causes gun to not go into full battery or if it does go all the way i get light primer strikes.

Now my Sig X5 Legion, you can literally load the OAL to 1.160 and it will not rub against the rifling. I was thinking maybe my Performance barrel is defective but then again my 2.0 Compact version it is exactly the same. Factory loads work perfect never had any issues.

What worries me is the seating depth is so deep, I am wondering if I can be overpressure. your thoughts
