Greetings Micky,
Slow day in Geraldine yesterday? Here are a few oddies to round out your list.

2.7 mm and 3.0 mm. These were a couple of semi auto pistol calibres from before WW1. There was also a 4.25 mm.
.14 calibre. I think one was called .14 Bumble bee or something.
There are at least three .22 calibres using .222, .223 and .224 and .228 diameter projectiles.
.236. The 6 mm Lee Navy cartridge was called .236 by some but the projectile was reportedly .243 diameter. A .236 diameter projectile would be something else. More research required on this one
7.35 mm. Here is your .29 calibre in the 7.35 Carcano. .298 diameter projectile so .29 calibre.
More later,
Grandpamac.
