Hi Fellas, I just had a 6.5 SAUM reamer arrive from PTG. I've got a Savage here chambered in 260 Rem that I want to rechamber using the new reamer (I've got a magnum bolt head I'm going to fit up as well). I've been wondering if it's a problem given that I already have a chamber around the same length and the reamer will be cutting for a while without the pilot in the bore of the barrel.
My plan is to set the barrel up initially off the neck and rear of the current chamber then check that the chamber is concentric to the bore. Hopefully it will all be good and not a problem. My concern is that if the reamer runs off cutting the initial part of the chamber then I'm going to have an issue when the pilot moves into the bore of the barrel. I'm using a floating reamer holder which has worked really well before but I have always been cutting a fresh barrel so the pilot has been in the bore right from the start.
Any tips or tricks that improve my chances? The barrel is a factory Savage large shank 260 that I've trimmed down to fit a small shank action. This is a budget build to give this cartridge a try before starting on a new rifle. Would I be better sacrificing a bit of barrel length (it's 26" now) and just chopping off and rethreading the barrel so I can start fresh with the pilot running in the bore? There's plenty of barrel there to do it if that's the safest option.
