After alot of trial and error, I ended up with an 8lb trigger pull weight for reliable ignition with almost any 22lr round.
With some reservations I followed some advice from my rim fire savvy friends and went back to using the stock firing pin, instead of the Ext firing pin.
It's working great, Once it got through my thick skull that the methods used to make a center fire revolver more reliable don't apply to rim fire revovlers.
I've already put over a thousand rounds through it and the trigger is really smoothing out.
I had good accuracy and 100% ignition using Fed automatch ammo.
It was just my luck that a local store had it on sale, so I bought a lot of it.
I added a dawson F/O front sight and another speed beez 100 rd loading box/block, so now this baby is almost ready for the 2018 steel plate season.
Almost, as I need to find a cheaper speed loader carrier, as i'm not paying $35 + S/H for one speed loader carrier !
I need six and I would rather spend that money buying another 5K rounds of Ammo !
