I used to have an ancient and un-dampened Texan, and taped an appropriate sized piece of heavy paper over the slot. That settled the beam a lot quicker, but remained a patience trier.
My RCBS 5-0-5 stops in about two seconds, and reckon others will too. I would be very wary of the Lyman models that have plastic bodies.
Bought a 505 new in 1982 and still using it. I love it, although I grew up with Reddings.
I throw a charge in the pan, set the pan on the scale;
Let it settle, dump charge into case and set case in the shell-holder under the seating die;
Throw the next charge into the pan and set the pan on the scale;
Position and seat the bullet into the case in the shell-holder;
Remove cartridge from shell-holder to loading block;
glance at scale, dump charge into next case, set case in shell-holder.......
The scale has almost settled by the time I set the pan and turn my attention to the charged case in the shell-holder, but is absolutely still by the time I've seated a bullet and moved the cartridge to the loading block.
I do things this way for safety and consistency, so the very little time it takes for the beam to settle is way faster than I need. If I were mass-loading for a pop-pop-pop auto, I'd be throwing charges directly into cases and checking every tenth charge. Even in this situation, the wait is nothing. I no longer have any autos and "paper-plate-at-25" is not my objective, so that influences my perspective and tempo as well.
