Very interesting stuff. Thanks for taking the pictures.
You make a good point that .05” would be quite a difference though, to this point, I’ve used 180 grain off the shelf loads exclusively - Winchester or Remington.
I can’t say I’ve had this problem.
Let me send you that spring. Not sure it’ll help but it’s not doing anything sitting here (haven’t managed to sell it haha). I’d like to satisfy my curiousity anyway.
