I guess the original 7.65 French Long IS the "7.62x22mm", but it isn't known by that designation here in the US. Maybe arms guys here avoid using that designation as it might get it confused with the 7.62x25mm Russian "Tokarev" rouind. Totally different. If you want common acknowledgement here from the guys that shoot it, referrring to it as the .32 French long or 7.65 French long will get you more understanding and help. I have recently taken up shooting and reloading the round with 62 cases I got from Buffalo Arms, but they were out of stock after I bought that partial lot. They plan to run some more in 2013. I measured a fired case at .772" after firing, coming in a tad longer than a 9mm Luger case at .750". True French ammo might be 22mm long, but I don't think the converted cases are, even unfired. There are variations in all manufactures of ammo, so minor variances are not of too much concern. Off the top of my head, I think I loaded 85gr Hornady .30 Luger bullets with 3.6gr of Unique, and got close to 1100fps in my 1935A, but don't hold me to it: check around for recommended data.
