WWB ammo size

I recently had my Glock 36 FTE while shooting it . I was using wwb ammo . I also had some Hornady ammo on hand also . The hornady ammo ran fine. I had probally 6 fte out of 50 rounds with the wwb . I measured the rim dia. of both brands of ammo i had and the wwb was .472 and the hornady measured .474 . My sierra reloding manual showed a 45 ACP case to measure .480 . Why all the different readings ?

What a weird set of circumstances. Your rim measurements are also weird. I don't know what to suggest.

BTW, is FTE failure to extract or failure to eject?

Win. WB is garbage. Pure & simple. I'll never buy nor shoot another round of it. QC is non-existent. For my money Fiocchi, S&B & Speer Lawman are the best bang for the buck for range ammo if you don't reload.

The SAAMI spec and tolerance for the case rim on the .45acp is .480" +.000" -.010" so all your rounds rims are within spec.

Here are the cartridge and chamber dimensions from SAAMI.

Your FTE issues are most likely not related to rim diameter.

Failure to eject is what I meant . Thanks for everybodys replies . Some of the wwb cases went down to .471 . This may not be my fte cause but I cant help but believe this is not helping the situation . If anybody has any 45 ammo they could check the rim diameter of I would appreciate it . Thanks

Manufacturing tolerances, mainly.

I've seen similar fluctuations in many brands (just checked out some Sellier & Bellot .45 230 FMJ and saw similar variance of .472 - .475 under the maximum dimension of .480) and it is not unusual. The Hornady and WWB seem to be closely specced in regard to that dimension, being within .002" of each other.

Nothing to worry about.

I have never had any trouble with WWB.
