I have a 4 hole lee classic turret and just getting started loading rifle (270 winchester). Saw the post from Dave about using the uniflow with the hornaday linkage to make it a capd. Looking thru the catalogs it lists the CAPD (hrn050073) and a CAPD lower unit (hrn050074). My question is, is the lower unit a requirement and if it is how does it go together?
The Hornady Case Activated Linkage kit will work with an RCBS Uniflow powder measure. The Hornady drop tube has the same threads as the drop tube on the Uniflow and the linkage bracket attaches to the Uniflow in the threaded area on the powder measure body. Except for using simple hand tools to screw parts on the Uniflow, no special modifications required.
Ah, on second thought, the lever arm that rotates the metering drum may need some adjustment. I did not look at that just now. But the holes in the arm may match the screw holes in the Uniflow drum. Also, you may need to go to the hardware store and get some extra screws for the drum, maybe not.
I am pretty sure the Hornady kit (#050073) comes with one powder drop die (#050074) so for starters, you would not need to buy another powder drop die. The picture on Midway's web site shows the drop die included.
Extra powder drop dies are handy if you change cartridges on your press frequently. You adjust the additional die for each cartridge. Then you do not have to re-adjust the die. The position of the powder drop die is critical for the proper operation of the powder measure and it is dependent on the length of the case.
Instructions should come with the Hornady kit, if I remember. I bought one to mount a Redding 10-X powder measure on my Hornady progressive press. If not, you should be able to get the information out of Hornady.
Hope this helps.
