The key is to use a smith that does the action tuning and work for you when they put the barrel on. Once it's done, it's done... other than replacing a spring when it needs it.We should have that thread. I'm putting a Tubbs pin and springs into a rifle to replace factory parts, but have had Gre-Tan recommended enough times that I'll probably try one of theirs.
I don't know of any methodology for comparisons here other than no mis-fires, no excessive spring grab on the pin, and no primer piercing.
