Trying to load .22 TCM with my RCBS Uniflow, case operated linkage on my turret.

Using W-296 for the first time in the measure.

When I reach the top of the stroke there is powder dropping around the top of the case. Never had this happen before and can't figure out where the powder is coming from. :banghead:
 
I do not have that setup but I would check the measure and drop tube for being loose or not in alignment. If OK then look at the linkage for out of adjustment. Does this happen with only that caliber. If so what is different with others that DO work? Good luck tracking it down.
 
Are you pausing for a moment to allow the powder to completely drop into the case?

Does it only happen with this powder, or with this caliber?
 
On the Hornady case activated drop there's an internal drop tube. There's a small (something like .17 to .25) and a large. If you use the wrong one, powder everywhere. Maybe your RCBS has a similar piece and you're using the wrong one??
 
Sasquatch, that's what I found. The way the RCBS is set up the small rifle isn't long enough to use with the TCM, so I had the pistol drop in. When I measured it had an inner diameter of .25. So for this batch I'll use the drop manually, I found the parts for that. Now for a call to RCBS to see if they have a solution.
 
If the design is the same as the Hornady, you shouldn't have much trouble getting one made if you can't find something offered by RCBS. RCBS might even be able to make it if they don't stock it.
