7 SAUM chamber question

[deadwolf]

Many smiths will chamber for certain actions, including desired freebore. Generally the actions that we know to be of top quality. Bighorn, Lone Peak, Defiance, impact precision, BAT, et cetera. Blue Mountain precision comes to mind. For example, I have a lone peak Fuzion ti, I could call and have him build a prefit for it in my desired chambering and freebore and have it shipped to me.

Are you guys that are extending freebore buying prefits and having a smith extend or are you better off getting a blank and having a smith do it all?

That's a question for your smith. Mine was fine with it either way. Also, ive been told carbon six will now extend the freebore if you provide them with a dummy round. They just started providing this recently. As I ordered my barrel last fall and they couldn't do that at the time, but I would confirm with them first.

I have been thinking about putting a prefit on a Tikka.

I ordered a barrel from preferred for a tikka and they let me do a custom freebore.

I too would be curious how long you can load the 155 hammers?? My smith will be extending my throat to the dummy round with that bullet. The eld-x must really be pushed down in there it's even longer yet.

Carbon ring shows up in your barrel.

I know where it shows up. I’m asking when are you seeing it. I’ve shot a pile of rounds in my rifles and haven’t noticed any of those issues.

It really varies with powder quantity, type, cleaning regiment, and even excessive freebore.
Neglect cleaning and it'll show up eventually

10-4. I guess what I’ve been doing has been warding off this dreaded condition. Seems like going through the trouble and expense of adding freebore ain’t worth the squeeze.

Thank you very much.
