The Interapid 312B-15 that nearly everyone uses, has a 2.675" contact tip and is a .0005" indicator. Precision and accuracy are .0005". Pretty easy to see .0002" or less when dialing in a barrel.
I'm glad you said that. I have two barrels on my bench right now, one is a center turned rifled 20 ga slug bbl for a neighbor that I will be single-pointing the chamber on, through the headstock, no spider. The other is a .20VT that will be chambered on the steady. I'm not fond of outboard spiders, but it's all people talk about doing anymore.I have my own way of chambering barrels that works for me. I dont use a outboard spider and I mostly chamber through the headstock. Try several different ways and then decide which one you like best. Theres no right or wrong way to chamber a barrel. If it is accurate to your or the customers satisfaction, then its right.

I thread barrels every day to build integral suppressors for pistols. . I indicate off the bore with a pin. Its not rocket science .
