[QUOTE="RockyMtnMT, post: 1310577, member: 7999"] I can say that my current Lilja barrel is 100fps slower than the last from McGowen. Same length and same reamer. Different action. With most barrel makers having a .0005"+- in tolerance pressure required to get to vel has to vary too. We received barrels from another barrel maker that were over spec to the point that our smith was not willing to chamber them. I think many smiths would go ahead and you would never know. Given the tolerances in off the shelf rifles I am sure there are some large dia bores available. Point being some barrels are going to show more pressure than QL and some less. Start low and work up.
