I do not believe so. The rollers change the gap. Or at least that is how the system is designed.
I most always run the Hi impulse LP in my CA89-10. I put in the Lo LP and the BG increased by .10mm. Is this normal?
That’s exactly my understanding. I will install the Lo LP again & re-check.
Mike at TSC explained it shouldn’t, but it might. That’s why he suggested I buy the 80 degree locking piece (if that’s the one I planned to use) to go along with the B&T barrel install for my Sp5k.
Did Mike explain what could cause it? A worn LP? Worn bolt?
Good link posted by @darkness on another thread. Scroll down to Bolt Gap.
Bob Schultz said if the gap decreases, it is generally wear to those three points outlined in the link. However, he said changing out the LP or rollers is essentially delaying the eventual issue, the trunion is wearing and will need to be replaced.
Thx! I’m suspect my Hi LP is worn
I don't think so. It's the trunion that wears.
