When I chase threads, I crank the barrel down to around 100 ft pounds and break it free - 3 times. This is to seat any thread that might be a bit off. It bends the threads into fuller contact. Then I look at the timing.

I once did an Israeli where I chased the M25x1.5 to 1"x16. I did not reseat the threads as above. After 20 rounds, the barrel was loose.
