I've come to the conclusion that getting wrapped up around "feel" is a convoluted affair. The feel is related to how your mags are tuned, what cartridge you're running, the relationship between your triggers sear and bolts cocking piece.
When I got my first TL-3 I was immediately dissapointed in how it felt. Right out of the box, without trigger. Because of the infamous binding and from reading/ listening to others gush about how buttery smooth their TL-3s are. But when it comes down to getting behind the rifle and running the bolt, I never bind it.
This is how it's been for every "buttery smooth" action I've heard about and then handled. Exact same reaction when I felt my buddies Impact. I immediately got it to bind by lifting up on the bolt handle at the full rear position and pushing forward. I keep trying people's super-duper actions, testing them if they bind....even though it's a non-issue when actually running them. In fact, I was seriously un-impressed with my buddies Impact. Granted it was filthy, but not the white unicorn everyone has been raving about IMO. Same with another friends AXMC. He was running it filthy and it was super rough. The only action I felt that I immediately thought, while finger fucking it, ..." ...this lives up to its reputation" has been a Lone Peak. It was being run by a gunsmith who had tuned the cocking piece. Its almost like it ran itself on inertia after you got it started. (Now you'll be let down if you run one based on how you're imagining it right now). Yes, I could get it to bind slightly as well.
The feeling on closing the bolt comes mostly from the cock on closing. I measured protrusion of the back of the firing pin from the shroud and filed the cocking piece until I had about. 005" cock on closing. That helped immensely. My 2 TL-3s and Origin feel MUCH smoother now.
Once I got the cocking pieces tuned, I couldn't get over how rough stripping a round out of the mag was. I never had a malfunction with them, but it provided enough resistance to ruin "the feel" so I opened up the feed lips in the front. Now it "feels" way smoother.
Nothing of substance has changed, but my guns "feel" much smoother.
Also, I agree: black...or you shoot bolt action Valkyries...?
