Anyone running this 10MM or 40 cal in 10MM revolvers.  I intend to soot ESR Division with mine using 40cal brass.  My Ruger GP-100 in 10MM should be competitive .  I made Sharpshooer in this Division using my GP-100 in .357 Mag.  The 10MM shoud be faster with moon clips.

Thank you Don for the welcoming comment.  I would strongly recommend the MC stainless version.  The gun comes with trigger and hammer shimsm a very nice trigger, chamfered chambers AND a stainless barrel and frame.  The latter can be blued,  My comments might be for not if the blued versions have those features.

Bought one in July, 2020 and I love this 5" GP 100. The cylinder mouths are a little oversized so I'm looking for someone who makes a 175grain SWC lead with a .403 diameter bullet. Best group so far is 2.25" at 22 yds with Selleir and Balloit 180 10mms.

Why?  You want the cylinder mouths to be larger than the bullet.  The last thing you want is the cylinder mouths to size the bullet down.  A bullet sized .401 will be sized down by the barrel and provide a seal and a tight foit to engage the rifling.  The usual problem with Ruger revolvers is the cylinder throats are to tight.  My GP 1-- in 357mag had cylinders moiths so tight a .356 bullet would not pass through them.  I had the mouths openned up to .358 to allow my bullets to pass through the cylinders without being sized down.

I am afraid I am not much use tp the OP.  I bought mine last fall.  A Ruger GP-100 MC.  Love the revolver.  Still working on loads for the gun and now waiting for some thicker moon clips from Ranch Products so I can shoot 40 cal in the gun.  I want to shoot IDPA ESR Division with the gun using the shorter 40 cal cases. 

The GP 100 MC is the first Ruger handgun I have bought that did not require some TLC to work the way O wanted it to.  Trigger was very good OTD, sights were bang on.   I may decide to cut the forcing cone to 11 degrees to better accommodate lead bullets.  That aside great revolver.  I likely will carry it on my Wilderness Permit
