I have my own methods but it's always important to reassess from time to time as products and idiologies evolve. What do you use and the reasoning behind it?
I've seen some barrel mfg's recommending 609. 620 has better heat resistance, although not bullet proof. JB having the absolute heat resistance. Shimming is more complicated, although, likely has the greatest impact on groupings. And in the "none" category... lapping is sufficient and benefits of bedding are too marginal to matter.
What say you?
