which finish reamer for 9mm

[newageroman]

Bull shadow upper has a tight chamber. I'm considering reaming it so I can seat bullets a little longer. Which reamer would you guys suggest? I'm thinking about the ones that are pull through, but looking for options. I have a spare 9mm barrel to practice on.
Thanks

Any thoughts/opinions on this? the case length is GTG, I just need the leade extended a bit.
Thanks,

Get a carbide reamer. The shadows have have hardened barrels. If I were you, contact “MemphisMechanic” in the Enos forum. You’re a member there to so it’ll be easier for you to message him.

He reamed three czechmate barrels for me last year and turnaround was very quick.

Manson makes a reamer for this purpose.

I already reached out to the mechanic, on enos and well see what he uses, I believe its a carbide reamer.
I don't have a shadow yet, but I doubt this will be the last project 9.
Will check Manson Reamers.

Just to clarify, what you're describing is a short leade - not a tight chamber. A throat reamer is what you want instead of a finish reamer. If you don't feel like buying one White Rock is my go to for rentals. He's old school, which I find rather refreshing these days. I've used Patriot Defense's 9mm reaming service a few times and been happy with the results. Quick turnaround too.

Yes, Exactly, Thank you for the correction!

Now I'm wondering/awaiting word on if these Bull Barrels are hardened steel (like the shadows), or just normal 75 steel. I'm only asking because the reamer guy asked. If its hardened I may just send to him(has carbide reamer for the hard ones). If not I will just get a Throat Reamer and go slow.

I have a box of 2k RMR HPs and all the stuff to go in them. I will load up my remaining RN to run in the Bull For now.
Thanks for the info. I'll check out White Rock.

A call to Patriot Defense would most likely answer your hardened barrel question. I know they have two prices levels, with the hardened/coated barrels costing a bit more.

Got the finish reamer from Midway about 4 weeks ago. Havent had the balls or motivation to try it yet. Until last night. = FAIL...
I didn't have any cutting oil so I used WD-40.
Was going to use my fancy new ratching die handle, and the die is too big, it wont fit - had to spin by hand - totally doable but the handle would be nice.
Trip to wal-mart just now, no cutting oil, waste of a trip. Orielys didn't have it either...
I can see it removing material, but it is really slow. still I made some progress on seating the bullet deeper into the chamber.
I have an old SP-01 barrel so I tried it first - the RMR 125HP (that is so plentiful right now) will *almost seat. when it does seat, I will take that measurement and keep going another 10 thous for safety (ogive variance).

Northern Tool has cutting oil on the shelf if you have one nearby.

[George16]

Any of the auto parts store in my area carries cutting oil. I got mine from Advance auto parts.

[newageroman]

Well... got cutting oil and.... SAME..

With fresh fancy bottle of cutting oil and tried again, but didn’t get much material removed. It seems like its bottoming out on the chamber mouth(which is good), but the angle of the leade of the reamer doesn’t allow for any deeper cuts. So… we’ll call it finished….
Loaded a new NAS3 case with a bullet and continually seated it down until it would just barely plunk.
COAL - 1.076”
So safe COAL will be 1.066”(.010 extra) or 1.071”(.005 extra) for this bullet/old SP-01 barrel - but I doubt I will ever use/shoot this barrel again so it was just practice.

Now when I did the same process to the Bullshadow barrel, I wasn’t able to get quite as much reamed out of it as the SP-01 barrel. Even with cutting oil and putting a tad bit of pressure on the reamer, it still bottomed out to...
Absolute max COAL is 1.056”
BullShadow Safe is COAL or 1.051”(.005 extra)

So... keep this in mind for the custom jobs/barrels/ the 1 bullet that is so plentiful right now does not like to be loaded long (read 9mmMaj).
The plan is to just load kkks of them at this lenght in minor PF. If I get my stuff back up to major I still have a few 124PDs.
Also note that the reamer lead flutes seemed to have the same truncated cone angle and shape of the 124 PDs as opposed to the truncated RN HP style of the RMRs. Do they make a reamer that has leads for JUST cutting the leads where you can adjust the depth with a lockring or whatever? I think that would have worked better in my case. Done with it for now. Calling it a lesson learned.

Anybody needs to rent a reamer, I got one...

If removal is really slow, you may have dulled the reamer on a hardened barrel. Ask me how I know.

Now when I use my reamer I go really light to see if it cuts. If it doesn't I stop and wonder whether I should just go buy a carbide one and then just ship it to someone who does it for me.

[mrcabinet]

Can you post a pic of your reamer? I swear it sounds like you got a chamber/finish reamer instead of a throat reamer. I've never seen a throat reamer that would stop on the chamber lip.

[newageroman]

lol... that would be my luck. I will look into this further. thx.
