[QUOTE="tobnpr, post: 2746300, member: 68758"] Every barrel manuf is different; McGowen cuts them to length after lapping, so you get what you ordered- no cutoff required. It's obviously true that the chamber reamer negates the need to cut off the breech end- but there's still considerations IMO depending on the chambering method you use. If you indicated the throat area (or at least somewhere further into the chamber), then drill/bore before reaming everything behind that area is true to the indicated section. If you indicate the breech end (or set up in the steady), and run in the piloted reamer- you run the risk of selecting an oversize pilot if the very end of the barrel has been belled out from lapping. With this, be sure to select a pilot that's snug fitting further up the breech, and it may be loose at the very end. JMO [/QUOTE]
