R93, as an experiment do some revolver loads with a nice rounded crimp and bench rest them at 50 metres against some uncrimped loads. You may be surprised at the results. A good .38 Special load from a good revolver should manage at least 50-75mm 5 shot groups at that distance without fliers, subject to you having good sight picture and trigger control. I think you will find that impossible to achieve with uncrimped loads. Your revolver should also outshoot your .40 semi-auto pistol at all ranges.

I will give it a go as I didn't know a crimp could improve accuracy in a revolver. Learn something new everyday

My 586 is pretty accurate as is with both 38 and 357

However I do doubt I could shoot a 50-75mm group at 50 even in a ransom rest no matter how good the ammo

The 586 is a superb revolver and easily capable of 50mm groups at 50 metres with good ammo. I used a 158 grain lead SWC over 2.9 grains of WST (and a good crimp) in my own 586 to achieve that accuracy. 2.4 grains of WST with a flush-seated 148 grain HBWC will do one-hole groups at 25 metres in both the 586 and my K38 (my preferred gun for ISSF centrefire match).

Yup will give it a go. I am sure the gun is capable but I doubt I am.

I have to load some ammo for the weekend so will do some up with a crimp and see how I go.
