Loading block to get easy access to rounds during competition shooting. Aids in counting and keeping track of details. Specifically for the ISSF 22LR details, which is shot as 60 rounds, in strings of 5, with sighting shots in between. Therefore 2 blocks, one holds 60, 12 rows of 5, and one holds 30, 6 rows of 5. Staggered in height to aid my large butterfingers to accurately pick up the small 22LR rounds.
