PPU .22 Hornet
I bought some PPU 45 gr. soft point ammo (not here) that will not chamber in my H&R Handi Rifle.
I took some measurements, and it appears the shoulder is too far from the base.
SAAMI says .853, I get .875.
The neck should be 1.017 and it's 1.052.
Beware of bargains in parachutes, hand grenades, dentistry, and ammunition.
Just a heads-up.
