The rcbs is easy to use dropping the bullet into the window and does a good job. My redding seater does much better with runout due to the case being supported during the process. What I found that eliminates the most runout is the bushing style neck sizers because they provide even tension around the entire case neck. I inspect my brass before and after sizing either discarding or using as a fouling shot.
I do prefer the redding dies much more. I use lapua brass if I can get it in that caliber because I discard fewer pieces of brass. I use nosler for my 300 rum with great results. I get more runout when I use Remington brass.
I get .001-.002 runout commonly with the redding always correct down to .001 or smaller. I get .003-.005 with the the rcbs, but still get a good many in the .001-.002 range. I measure contrencity using both Sinclair and hornady but I correct using the hornady (I do get some small differences in measurement between the two). If I can ever get a redding competition seater for my 45-110 sharps I would be in reloading heaven.
Saying all that I am happy with results of both but prefer redding. I got the rcbs on sale and at the time needed to pinch some pennies.
I fool around with a lot of different bullets and bullet powder combos when I'm searching out a new load. I found the Redding die sets to have way more backlash built into their micrometer heads than the Forster. Have only seen one or two RCBS Competetion die sets in my life time, so won't say much good or bad about them.
As for a 45-110 seater: piece of cake if you got a reamer. You can use either a 45-70 die from Redding or Forster (you can buy the sleeve from Forster or Sinclair. Not sure about getting spare parts from Redding as I've never tried it. Redding copied Forster's design, so the rest is easy. As for the micrometer heads, I think all Forsters are interchangable. I've seen one other micrometer headed die set in either 45-110 or 45-120, but it was pretty much custom built from the start. I'm assuming your filling these cases with black powder, and love the idea. I shoot two 38-55's, and have had the want for a 40-65 for eons (in a Hi-Wall of course!)
