FN ammo

[brandons]

hey guys what I was saying about the 5.7 ammo the casing is not streching its self the shoulder is bulging up which in urn makes the neck shorter. And this is with factory ammo not reloads.I cant reload because my rcbs dies will not resize it.I may have problem with gun need to know if anybody elses casing are doing this.Its happening with the FN bullet with the 40 gr V-max bullet.Nothing is happening to the primer . and the ammo is brand new from fn this is happening to

I'd at least take the gun and spent cases back to the dealer and see what his opinion is on returning it to FN.
