Hi all,

What reamers are folks using for the chamber in order to support the 80gr and 90gr bullets? I'll be shooting long distance, in F-TR. Obviously until I can test the Berger 90gr VLD's I will not know if my barrel will like those or not, but my preference is to include reamers which support that bullet. Any information you can share would be great, especially from active F-TR shooters :)

Thanks,

The best thing to do imo is to get some 90gr bullets seat one in a casing so the bullet shank boatail junction of the bullet is at the base of the neck ,this is where you want the bullet seated for optimum performance.

Then using a bullet comparator [and a bit of simple math] determine how much freebore you need and order your reamer accordingly.

Call pacific tool and gauge and talk to technical suport if you want they should also be able to offer some good advice.

Coyote your are right seat the bullet like you said and send it like I did to
"JLK and let them build your reamer with live pilot on end of reamer, make sure to get one that fits bore dia of your barrel diameter perfect. You will only get change back from $300 for a custom made reamer, go one step further and get a Forester Micrometer blank bullet seater and get your smith to use same reamer on bullet seater, sure ends runout.
the other option is get there standard 223 reamer and get a throating reamer
and let your smith lenghten throat for 90gr bullets.
I answered a post similar to this on another site and fellow knew my name and Called JGS and asked for same reamer JGS answer was we do not give out information on any customers custom reamer specs.

Interesting.. that is actually really cool of JGS!

I've got a Wilson micrometer in .223, so I'll need to pick up a VLD stem, but otherwise I think I'll be good.

Actually I've got a follow-up question. If I have a reamer designed to handle the VLD's, will I be limiting myself to VLD's, or should I be able to shoot the other 90gr's available? (All other things being equal of course)

By tuning the freebore to a certain bullet it limits you a bit ,but I see no problem with other bullets some might be out a bit but will still work.

Depending on what you want to use the gun for it would be best to set it up for one thing.
If you plan on shooting F-Class and want to shoot 90's set it up for 90's and if you decide one day you want to shoot some 80's they will still work but will be seated out a bit no big deal it will still work.

I don't suggest measuring a round and sending the specs out for a custom reamer, unless you have an optical comparator and know what you are doing. If you want a custom reamer send the dummies to JGS and let them take responsibility for giving you the right thing, after all that is what they do, day in and day out and they do a very good job at it. Using a throater is a good way to go I think works fine if your GS knows what he is doing, it gives the ability to customize perfectly to your dummies.
 
First you have to deal with twist rate before you concern yourself with freebore. Running 90's thru your existing barrel may be a lost cause if it's to slow. If you have a 1 in 7 or maybe 8 then you're likely in the ballpark and you can start from there.
