Assume that the price was very reasonable. If you're a dedicated brass sorter, would you buy a cartridge tray like this? It's made of 1" thick Sintra with rows 10 deep. There is a space between rows 5 and 6 for the running weight ID.
The finished product would have a blank space at the beginning of row and and then be engraved with .01' .02. .03 etc up to .09, and then begin with the next whole weight number as in 170.0 etc. Only the 1/10th grain increments would be engraved. The whole figure would be left open to identify as you saw fit. This one is a full three grain spread.
So waddaya think? Useful? This one has masking tape along the rows with the increments written in marker. A finished product would have those 1/10th increments engraved.
NOTE: We don't sell to the public. I'm just testing the waters for interest.
