How many of you who shoot 30 carbine in your Ruger Blackhawk have experienced sticky extraction?
Have any of you who did have sticky extraction have the throats corrected and noted a difference?
I posted these questions elsewhere and pretty much they went largely unnoticed so I thought I would ask you guys about your experiences with sticky extraction in a 30 Carbine Blackhawk. I can't be of any help here, because while I have owned a few, they shot fine and I never had any cases stick.
I checked with Harton, and we agree, where a bullet is .308" diameter, and the throat is .305" or so, upon firing the bullet is being swaged down so it can exit the cylinder which has to increase dwell time which leads to an increase in chamber pressure, as that pressure has to go somewhere.
Rough chambers are another suspect. Of course there is always the possibility of ammunition that is out of spec. Does anyone have any thoughts?
While I am at it, I am looking for a .30 Carbine Blackhawk cylinder. Let me know if you have one to spare.
Last, I am considering running the 32 640 Miha designs again in 100, 115, and 135 grain HP weights but this time sized for the 32's AND for the 30 Carbine (.309"-310"), so, a show of interest here would help me know if there would be enough takers. I dont think this has been done before and we already know the designs are excellent performers. Why leave the 30 Carbine guys out?
