Appreciate the offer. I was able to install it. I overestimated how hard 300 (more like 330 in my case) degrees would be. It crushed quite smoothly through the entire range - I think the grease helped.
Yessir. I’ve seen crush washers crush unevenly. You end up with an oval that’s a bugger to remove later on without possibly messing up the barrel threads. I end up cutting them off. When I use grease, I never have that issue.
