Thank yo for the information, greatly appreciated. My last tuning of my V22S bolt is 4 turns out with a 20 b spring. The index from screwed all the way in is 3/4 of a turn, so the bolt is now 4 & 3/4 out. I test my V22s using the Eley x-shot targets, for me groups don't seem to tell me much. Shooting for score on the x-shot target tells me how I and the gun are doing. My last two targets shooting a new lot of center x are the best I have ever shot with the V22S one was 250/250 x18, calculated group 9.03mm, the other was 249/250 x17 group 9.79mm. So I am at 4&3/4 turns with a 20lb spring. I like the results a lot but don't know how I got to this point with the bolt, other than trial and error. I want to understand how, not trial and error. Mike Bush says the VG video is not how to tune the bolt, waiting for his reply to my how-to do-it question.
You've got one on me, I have no idea what the SD/ES numbers are on the ammo I've been shooting. In the last 12 months I've probably shot well over 50 different lot #'s of ammo.
Like yours one of our pins is 3/4 turn and the other two are only 1/8 of a turn from index when the pin is all the way in. This is one of the very noticable differences I've found. Another is none of the three pins turn out the same number of turns from index to touch the bolt nose. These differences are the reason it's difficult to go by how others set up their firing pins and springs.
Yes, I already have a single shot adapter mag buffer and already have a action design for a dedicated BR setup flat bottom with mid locking lug as the next project once these are smooth production
Def looking forward to your BR action with left port.
