Thanks Gary

I am still interested.  Would you be completing this build?  I don't know much about barrels.  I don't have the resources or know how to complete it.  A faster twist might be better for todays longer bullets.  29 or 30 inch would be about right.  That is a nice heavy barrel. 1.250. I mean a heavier barrel sounds better to me.  Has this rifle been well used that you managed to need a new barrel already?  Why are some rifles using a 12 twist or 13 twist and others are using a 11.25" twist.  While hunting rifles appear to be using a 1:10. What kind of chamber did you have in mind?  You must have put some thought into this already.  What other mods?  Adjustable or raised comb, adjustable length of pull?  How about the means for attaching a bipod or not?  I'd probably just use a proper rest. The duel port single shot was my first thought that I wanted to go with.  What would you suggest for a scope?  You have my interest so far.  I just recently decided to entertain this idea.  This is all new to me.

I am wanting get started in some bencherest shooting with a Single shot 308 win.  The Savage Model 12 BR single shot with duel port in 308 win and a 29 inch barrel caught my attention.  Doesn't seem to be available any more.
If someone has one for sale you can contact me.
