R700 is between 1/9.25 and 1/9.5 twist.
Didn't need to clean it but was curious about the specific twist. Which,after 3 dry mop passes,kept coming up the same..... and the barrel was good to go after the second pass. Only thing coming out was a slippery black graphite like fouling. Nice distribution as well. That was probably 40-60 rounds.... 2/3rds H4198 @2000fps and about 1/3rd of that count was jacked up Varget load @2500 or so.
Chamber neck is .316.......130g Lee is @.313-.314 OD neck on no turn Hornady brass.

.3155 is what the stainless 24"Shaw pre fit Savage barrel is. New slow twist Savage factory barrel has the loosest chamber neck @.3165,and pretty much no leade.... has a little freebore then......lands start. The P.O. didn't get through a cpl boxes before bailing and that's exactly what the chamber looks like.
I'm good on neck clearance. Gonna hopefully get the "gunsmithing" part done today...... if you can call screwing a barrel in, smithing?
Not real enamored with the wooden block fixture for milling the bullet bases. May make a better one? out of aluminum. The fixture needs to have shoulders cut so they ride on top of mill vise..... which is a touch faster,more acc than parallels. And make it hold more than one bullet. It can be a two pce block instead of the split arrangement. I'll come up with something.
Thinking about trying IMR4350 first.... see how close I can guess at 3000fps..... right out of the starting gate.

ITS, don't know about your level possible investment in this, but a simple 5C collet fixture that you can put in a vise or clamp on a mill table and the proper size collet with a depth stop would be the berries for holding small cylindrical parts square w/o distorting them.
Here is one I have that works well and is versatile in mounting.
Another few dollars for a collet and depth stop and your set for milling, drilling HPs, etc.

Yeah Ian.... here's one..
I got a chop saw and a trim gun and a sLowes acct. so I must be a "trim guy". And yes,I still owe you a crown, cope solution.
I'll be a gunsmith,only when I get off me arse and learn to grind a "proper" chamber reamer. Got the equipment,plus some..... just isn't a driving force right now.

I haven't seen any for R8s but that doesn't mean they don't exist. I do think 5C collets are cheaper and more widely available in more sizes than R8s. Plus you can buy emergency collets in several flavors for boring your own custom sizes. Before we started using 5Cs on everything we made custom vise jaws and lathe fixtures and its just easier now to grab a collet and the right holder and get to work.

Yeah, I never claimed to be a trim carpenter, I just 45 or 46 everything upside-down and backwards against the fence and color-putty the gaps and nail holes 
. Looking at millwork and carving done by hand on some old mansions around here, shake the head. People had skills. Stonemasons too, scrambled eggs carved on limestone corbels and keystones with lion heads, neat stuff.
Does that qualify me to be a Glock Armorer? I got the pocket Glock multitool.....

Haha.... like I told you before,upside down works pretty much everywhere except up in a pediment. Which,is more often than most think.... dormers,front door surrounds.... and stupid cool breakfront Chippendale inspired cabmets.
Most $$ I ever made ever per hr was on a fr door surround. Worked out to 1140.00 hr. The guy was a "pedigree'd" lawyer.... freakin prick's family owned one,if not the most famous estate houses on the James river. We were at some stupid dinner party and the MFr started yappin his pie hole to me. "Dude,you can't afford my work"..... is all it took on my end to set the hook. But,the only reason I did it was cause his wife was truly,a nice person. And their house deserved it....

And for the record....this is what I'd rather be doing. Sheet,this is 1 of a dz ruins on a buds river front property where me and shopdog spend lots of time. There's a blacksmith shop on there as well. This pic was yesterday,got the B$L 3-9X40 sighted in and hit the killing fields. This is my 7-08 R700,EDC..... sighted in 1/2" high @100.
I made the H&I lube die for use in a Lyman 450 awhile back. It's what I've been using on the R700 7-08. Didn't put any leading edge chamfer or bevel on it,sorta because.....
In use on the Lee 130's I don't size any further than juuuust,past the GC,leaving/shooting as cast body. Lube is applied by hand. So today,the die's "stop" was set to reflect the length of the 130....oops. Which is normal M.O. whether full length processing a bullet(and lubing) or how most of my precision bullets get treated( just sizing GC portion).
Hopefully you got that last part.
So today because of the shorter 100g "inbred" bullet,the stop wasn't reached. Still with me? In this case,I visually "stopped" when just past the GC,barely getting into the drive band that's immediately above it. And remember,NO bevel on top of sizer AND we're not trying to lube....very easy to see.
Early impression is it's better to not set the stop height. As if any of this isn't hard enough to chronicle?.... trying to describe this soft sizing is tough. The GC is already seated fully,and with extreme accuracy on the milled bullet base by the little jewelry C frame press I made awhile back..... so the lube die stop isn't needed in that respect.
