What did you use to polish the chamber?
It's Saturday and again most of the guys are here working.I guess Bartlein picked up the pace, or I got lucky. It's been less than two months and my barrel has shipped. Maybe I just happened to pick a contour and caliber they had ready.![]()
I love that level of transparency Frank. Keep up the great work and products.It's Saturday and again most of the guys are here working.
In some cases if a order gets cancelled and the barrels have already been started and or finished will go thru the orders and put the barrels on the oldest matching order. Doesn't happen a lot but will happen once in a blew moon.
Also if we are working on a large order for a customer (lets say it's a 100pc order) we will automatically throw and extra couple of barrel blanks on the order...that way if we lose one during the run for that customer.....we are not scrambling to get one made to make the order complete but any extras if they match up with another order....will put it on that order.
Sometimes it's timing and luck of the draw when you place the order and what is being worked on out in the shop.
All that being said guys.....the gun industry is upside down flat out busy and I don't for see it getting any better anytime soon.
Thanks for buying the sticks!
Later, Frank

Wrap a single layer of 1/4” strip of scotch tape (3M 600) around a case (or ideally go gauge) with one edge aligned with the base of the rim, and polish until it fits?Suppose one could get a plug guage to measure.
Suppose one could get a plug guage to measure.
Im no expert and may be over simplifying it in my mind but couldnt you get a guage say around .5330+/- and see how far in it goes?Just a silly thought but....
For the most part your polishing a taper. So what kind of plug gauge you going to get?
Not poking at you at all.
Using just the tip...will get you in troubleJust the tip?
your killing me!Using just the tip...will get you in trouble![]()
I'd say yes but with a hard edge....how you gonna get a accurate reading with the gauge tipping/moving around.Im no expert and may be over simplifying it in my mind but couldnt you get a guage say around .5330+/- and see how far in it goes?
Just the tip?
4 kids, trust me i know.Using just the tip...will get you in trouble![]()
This is exactly what I do to use the Lee Collet die for made for 6.5 Creed in order to neck size 6.5 PRC.Can anyone think of a reason why a 300 win mag Lee collet die wouldn’t work for the PRC, possibly with the aid of a washer around the case body that sits on the shell holder?
Same here ... I have "TT Diamonds" in all of my precision rifles and love them ... no issues whatsoever. I squeeze - Gun go BANG !!!Yes sir. I have a special and a diamond. Single stages are great. Never had an issue with them.
This is exactly what I do to use the Lee Collet die for made for 6.5 Creed in order to neck size 6.5 PRC.
Just make sure the washer allows for enough of the neck to get sized yet not too little thickness that you start to buckle shoulders.
Could you grind down the top face of a shell holder to make this work?Looking a little closer at it, I think I’d have the opposite problem as the neck shoulder junction on the PRC is just slightly shorter than the winmag (.080 or so). It should probably work as is, although sizing that much less of the neck. Depending on how much vertical play there is in the shell holder I could probably make it pretty close to the same.
Could you grind down the top face of a shell holder to make this work?
You dont neccesarily need to size the whole neck. The SAC die is designed to only size part of the neck. Aparently the fireformed portion helps center it in the chamber.
Nice! Waiting on my barrelJust got mine built ten minutes ago, need to get a lower Spuhr mount. Time to start reloading and hit the range tomorrow.

Dude!! You and me both, makes no sense having .5cm on the dial is weird and a little embarrassing.I really want to try out the S&B 5-45x on my ELR rifle. Really wish they would change the labeling to 0.05mils instead of cm. Just annoys the shit out of me to see cm.
I have to assume they do it in cm because they’ll run out of space on the turret with all the extra digits for mils??Dude!! You and me both, makes no sense having .5cm on the dial is weird and a little embarrassing.
Naw, if you look closely at the turrent it is a five turn turrent and fully indicated.I have to assume they do it in cm because they’ll run out of space on the turret with all the extra digits for mils??
So I have a question for whoever. I've got a limited supply if reloader 26 (4lbs) and H1000 (7lbs). I've also got about 7.5lbs of H4831sc. Should I save my rl26 and H1000 until after I've fire formed my brass or should I just start working up a load with each? I really don't want to waste any powder right now and could use the H4831sc to fire form. The H4831sc does well in my 300WM but not as good as the H1000. I was going to use it as my backup powder.
I'm undecided on which one to use.
If you had a small enough paint pen you could put a decimal in there. I’ve only seen images online of the turret. I would easily screw up a firing solution thinking in mils and dialing in cm. My mind just doesn’t think in 0.05 mils to begin with and now I’d have to force myself that it’s really just 5. 10 is 1mil. I guess I could get used to it but it’s annoying.Naw, if you look closely at the turrent it is a five turn turrent and fully indicated.
It is a new barrel and I've got 5 boxes of 212gr precision hunter that I can use to break it in with and fire form that brass. I also have 100 new Hornaday brass with half of them being necked down 375 Ruger cases. I will have to do some comparison with fire formed brass to virgin brass and see what I can figure out. Thanks for the input.first question, is it a new barrel? If so then use a different powder to break in the barrel. When I say brake the barrel in, I mean shoot 25-50 rounds to speed the barrel up. Also a good time to fire form cases. Use this as a training evolution and practice wind calls, long range spotting, etc
Then use your limited powders to start load development.
all my barrels tend to speed up regardless of my cleaning schedule which is why I suggest putting 25-50 rounds down the tube. I hate developing a load just to find out it sped up 40 FPS or whatever

Got it all dialed in for a match and then got called to deploy early so I can’t go to the match. MotherF$&@er
I have never measured run out. I do want to get a measuring device for fun. There’s one out there that can also tap the bullet to fix runout but I can’t remember what it’s called.JB, those are some awesome groups. What is your average runout? I’m still trying to get my setup dialed for the PRC and I’m ranging .003-.006. I’ve always aimed to get to .001-.002. Trying to decide how far down the runout rabbit hole I want to go. My groups look like shit though and I suspect run out is a likely culprit.
Take your expander button out of your full length sizer die and throw it in the trash...and then use a mandrel after sizing....and you'll see most...if not all of your neck/bullet runout go away. Using a decent seater die that supports the shoulder and body and creates proper alignment....and you won't see run out.
it’s hard to diagnose things like this.
Jump test can show some weird POI shifts.
One thing I learned when shooting magnum cartridges up to cheytac sized cartridges is how important is it to control the rear of the rifle. Just changing my technique with that alone changes my POI and group size
also in my experience magnum and larger cartridges do not like long skinny light contoured barrels. This could be more than one thing going on. Maybe it’s something to do with barrel harmonics. Maybe it’s something to do with recoil management. Maybe it’s both. The Swiss cheese effect
so for me, if both those issues were present and also doing a jump test, I would see some wild groups
im just throwing stuff to see if one of these sticks
Below is a jump test with a 33XC with a light contoured barrel at 160yds. While one group looks decent, I could not get the rifle to shoot with Berger Hybrids or Hornady ATIPS. I have much thicker barrels on order.

I’ve shot a proof carbon barrel in the past.
I remember it not shooting so great but my reloading abilities have increased 100 fold since. I have one on order and I should be getting it in May. It’ll be interesting to see how it shoots.
but maybe it’s worth checking all your torques: action screws, scope base, scope rings, barrel torque, muzzle device(s), etc.
Parallax wouldn’t cause that big of a shift. Hopefully there’s no mechanical issues inside the scope.
sometimes barrels just hate the bullet & powder combination.
