Thread: A wee project for myself

Stripped it this afternoon and found the suppressor alignment was spot on, but the suppressor was full of lots of fine copper fragments. I pulled a cartridge and the projectile is made of powdered copper. The ammo was made for police use on an indoor range and fragments on impact. It probably works fine in a polyagonal Glock or MP5 barrel but is bloody awful in a conventionally rifled and ported barrel. Little pieces break off the bullets as they exit the bore, having been structurally weakened by the sharp edges of the rifling and passing over the ports, and the bullets go all over the place. I have a good supply of JHP 147 grain bullets so I will load up some sample loads and head back to the range for accuracy and velocity testing.

Its good when it turns out to be a nice easy fix!
