Maybe a sticky with the various calibers listed?

There is already reloadersnest.com

That's the way it's done on Sniper's Hide.

I've received tons of good data from other shooters posting their chambering, barrel contour, length, and load data, such as brass brand and length, powder type, primer, bullet, powder charger, and bullet relationship to the lands. When you scroll, you see trends based on your parameters. And sure enough, your load comes out shooting great, within those parameters.

It goes in stickies:

.223 only
.22-250
6mm
6.5X 47, 6.5 Creedmoor, .260 Rem
7mm (short action variants)

Ect.

It ends up being a long list of stickies, but you'll find helpful data if you spend 10-20 minutes.
