Redding Reloading Equipment is now making a powder measure adapter for their competition model 10x powder measure. The drop tube adapter allows the handloader to precisely charge .17 Hornet cases.
The measure is designed to provide precise throws of 1 to 25 grains, with the “sweet spot” being at 10 grains. The drop tube adapter for the .17 Hornet is available now and carries the part number of 03817.
The problem with small rifle cases is the chances of overcharging a case with catastrophic results is much higher than on a larger cased cartridge. For example, lets say for your given powder, the charge should be between 11.5 grains (min) and 12.2 grains (max.) If you try to drop 12 grains and accidentally go to 13 grains, you are way over the maximum for that load.
Compare that to a .30-06 where your charge may be between 42.0 grains and 51.5 grains. If you drop an extra one or two grains on a medium load, you aren’t likely to go over, and if you do, the effect is not likely to be catastrophic.
(Please note that the above powder charges are random numbers pulled out of the air. Do not use them for any reloading purposes! Additionally note that I don’t recommend sloppy reloading. Pay attention to what you are doing and drop the right charge…)
