7mm SAUM Reamer questions

[Rhysk]

To start with, just starting to get into F open and have now definitely found my self well in the rabbit hole.
have picked up a low round count 7mm SAUM here in WA. now the original reamer that was used on it might not be Available to me ( i have to look more into this )

Now what is the best way to go about this and going forward to keep consitancy and chambers similar for each new barrel is it worth purchasing my own reamer and providing it to the smith when the barrel is done ?
if this is the best way Who is the go to for reamers ?
now the next question is a custom reamer the go, like setting up a dummy round and having it cut to suit. which is only going to lead me into the next question of what would be the best COAL Plan is to use berger 180 and 184's

Any gunsmith worth their salt will have a 7 SAUM reamer. Specs between one reamer and another shouldn't be anything too dramatic I would imagine as the SAUM has been around for awhile and most have it figured out.

Depending on which gunsmith you plan on using moving forward, you may not need to buy your own reamer. If you do go down this path though, I'd talk to a gunsmith in the first instance, to get an understanding of what the specs mean on a reamer print. I've got several custom reamers and some of them have turned out to be duds, learnt via trial and error.

I run a custom SAUM Improved reamer with a freebore of .200 which suits 180s and 184 hybrids just fine. .220 is quite common but I prefer to go a tad shorter.
