i had a custom barrel made for me by SSK.
on its maiden voyage to the bench, i realized that one type of ammo doesnt chamber. my father's hand loads work, and 2 other types of factory ammo works. the fiocchi 240 jsp were the only ones that wouldnt chamber. i scribbled some sharpie on the side, and confirmed that it was a width thing, not a length thing. the issue is about 1/4 of the way back from the neck of the case. this ammo works fine in my SW 629, in fact, its been a great hunting round for me with that gun.
im trying to figure out if the issue is with a chamber that is too narrow, or the ammo that is too wide.
i have a set of digital calipers on the way. but thats only going to tell me the diameter. im trying to figure out what the diameter of the casing should be, and if it is in spec, i can reach out to SSK and have them fix the chamber, or if it isnt in spec, well... i know that i need to avoid that ammo. from what i can see in various places... they list:
Neck diameter .457 in (11.6 mm)
Base diameter .457 in (11.6 mm)
i also found the saami specs
https://saami.org/technical-information/cartridge-chamber-drawings/
if you click pistol, it is on pg 54(pdf page 63)
the ssk experience has been quite the disappointment. to say the least. but im not going to go into that right now. suffice to say, if the chamber is out of spec, that just means the quality of the product will end up matching their lack of customer service.
