[QUOTE="entoptics, post: 1756712, member: 104268"] Thanks for the replies, particularly [USER=68875]@lancetkenyon[/USER]'s data. The new rifle is a Savage 110 High Country, so factory "SAAMI" chamber. Don't wanna spend $35 for 20 chamber molds. ;) Exactly the type of information I'm after. From your data, it looks like I can aim for a 0.004" bump, and likely be able to chamber. I have 200 brass, so it's not exactly "a few bucks". More like 25% of the cost of the rifle. Also, in my experience new brass is WAY smaller than most chambers, and requires at least one fire form before it's close to the chamber. Based on lancetkenyon's data, and my own experience with other cartridges, fired brass will be much closer to the final chamber size than virgin brass. Unless I have a particularly tight chamber on the new gun, and a particularly loose chamber on the old rifle, it seems like once fired would actually be a better place to start load development than virgin brass. Where I shoot is 5 minutes from my FFL, and both are 25 minutes from my house, so having a handful of rounds ready would save me a bunch of driving. Also, with the stupid time change, it gets dark around here at 4:15PM. Depending on when I can pick up the rifle, I might not have time to make the trip. I'm a seasoned reloader, and understand the consequences/implications of brass sizing and chamber variations. If I truly get terribly unlucky, and the brass can't be FL sized down correctly, then of course I'll have to bite the bullet and start from scratch. Not gonna drop $200 till I know that for sure though... [/QUOTE]
