Picked up a set of these but haven't used them just yet.

Based on a visual inspection, the mesh is tight enough to catch chips. (2) screens per package.
I use the full-size tumbler (with a cap at each end.) Looks like they should make 'straight-through' rinsing much easier.
Anyone else use these?
I got those with the tumbler, tried them once, I didn't like taking the end cap off to replace them with those wire mesh strainers just to drain off the dirty water.
You can drain most of the dirty water out, without dropping any pins with no cover, that's what I do.
With those strainer caps you still have to remove one and dump the mix into something else to separate the pins from the brass, so just an extra step.
After draining off most of the dirty water I dump the mix into a wire waste basket that's in an empty bucket with a mesh paint strainer bag in between the wire basket and bucket.
I then add water and agitate the basket so all/most of the pins fall out and into the mesh paint strainer bag.
Move the basket/brass into a second bucket of water that has another mesh strainer bag to catch any remaining pins and agitate the basket again for a 2nd rinse.
Then a 3rd water bucket for another rinse, and a final water bucket with a heavy dose of Armor All W+W to "lube the cases for sizing.
That takes less time than typing this
Strainer Bags, LT$5 for 2:
TRIMACO 5 gal. Elastic Top Paint Strainer (2-Pack)-11523 - The Home Depot
HD has others:
HDX 5 gal. Elastic Top Strainers (2-Pack)-11573/36WF - The Home Depot
The black buckets and wire mesh waste baskets from the dollar store so $5-$6.
No more pins escaping...
Oh, and I pull out the bags with the pins in them and run the bag/pins thru the rinse buckets and W+W bucket for rust, then spread out the pins/still in the bags on a towel to dry them.
