[I'm having a bit of an issue reloading for .480 Ruger right now, finding that most of my reloads won't seat in 2 different cylinders on a Ruger Super Redhawk, stopping perhaps 1mm from fully seating and then seating with a modest amount of thumb pressure. The other 4 cylinders have no issue, rounds drop right in and out!
I seated and crimped in one step. Caliper measurements comparing every possible part of the reloaded cartridges I could think of with a Hornady factory xtp 325 round were all within .001. The factory rounds dropped in and out easily so it's a very subtle interference.
COAL is 1.632-1.633, well within spec.
Dies are RCBS and are dual-labeled for .475 Linebaugh/.480 Ruger
My idea is to check prior to crimping next batch- will probably shoot these. I have used a steel brush and a drill to make absolutely sure there is no powder, residue, etc left in the back half of the cylinder.
Do any of you seat then crimp in two steps with the RCBS dies? RCBS instructions advise that this can be done in a single step but I know that can be problematic in some situations.
NOTE: This only happens in 1 cylinder, binds very slightly in another. The other 6 Cylinders in the 7.5" Super Redhawk drop right in and out
