.25 Delrin hammer spring guide to reduce spring noise
Finally got a chance to tune a .25.
1st thing I notic was a loose spring near the hammer (no spring guide)– a lot of slop and you can hear it too. see photo, you can see the spring guide on the HSTA so I made a guide to fill that area.
Photo of Delrin guide when cock —-> not like the .22 this one is a little smaller OD then the Hammer so it dosnt hit the action as a free floating hammer.

Photo of polish hammer with Delrin guide with HSTA guide so you can see the clearance.
Also added de pinger in the AT
now this .25 sound solid with no spring noise, she shooting kings at 935fps and sound as quiet as the .25 cricket at the same FPE.

I’m worried about you , Zonkie …
I need to take some picks of mine with the Can on. As quiet as a quiet PCP with SS/STD cartridges. Muffles the muzzle crack on the 17 HMR & .22 WMR completely. Nothing can suppress that supersonic crack but it’s dead quiet by the muzzle = the quarry doesn’t know / can’t place where the hell the shot comes from.
