I notice that most of the folks on this thread shoot bullets other than straight lead.  I began by shooting a Lee 356-120 bullet which is between 115 and 120 grains.  The problem I found was that the lead bullet sized to .356 is a very efficient seal.  That combined with the R-51 operating system caused overpressure symptoms at even mid-level loads.  I can shoot store bought rounds all day but the lead bullets must be worked up from minimum.  The load I was shooting in my other guns which was 3.7 gr of Titegroup caused flattened primers that formed around the firing pin.  Upon disassembly of the pistol and removal of the firing pin I found several discs of metal.  They were from the primer separating and following the firing pin into the Pederson block.  Not good.  If you are loading cast bullets be ware and start from the minimum load recommended and work your way up.   

Does anyone have a favorite hand load for the R51?  I had worked up a load using HS6 and cast lead bullets for my Smith and Wesson M&P.  When I used it in the R-51, there were indications of over pressure.  I am assuming that because of the delayed blow back system, pressure builds up on a different schedule than in a traditional recoil operated pistol.  Any thoughts?

I was looking for a forum to discuss the Remington R-51.  I purchased my pistol about two years ago at a local gun shop here in southern Nevada.  I am usually able to get to the range about once a week.  That being said, I learn something new about this pistol every time I go to the range.  I love the ergonomics.  It draws from the holster easily.  All in all I really like it, I just need to keep working with it, and continue to learn about it.
