6XC plinking 1cent brass

[Tesoro]

I just made my first ever re-formed brass from a 308 range scrounge 1x Win. It is all to spec and seems like it should work just fine for varmints and steel practice etc. Any reason why this wont do the trick? Necks are .135 +/- . 0003. I dont mind the work but there are plenty of times when I am in the field and just want to shoot and move on.

Range pickup will work fine, unless it doesn't.

If it is 1x then it is 1x. or u buy a bag of 1x

The problem with 308 brass in the 6XC chamber is the diameter at the 0.200 line. The 308 is bigger causing problems. You also may have neck thickness problems. I just use old brass if I am not going to pick it up.

. The brass fit fine in the final 6xc tubb die after running thru a 7-08 n 243 gutted std die. All got squashed upwards and trimmed/shaved. I dont see a prob. It is reformed just like many converts. Am i missing something i’m not thinking about?

Calm down, its Xmas

Only thing I would suggest is to turn the necks a little. Other than that, it looks like it should work just fine.

@AckleymanII used to make 6xc from Palma brass.

Tubb chamber is 275 neck. So you could even have pretty fat necks.

I'm pretty sure it should work fine.

Be sure to re-anneal after forming. Didn't see that mentioned.

Not a thing wrong with the use of range fired brass in 308 or 223, when found, cleaned and prepped. More often than not it is once fired and will serve well for you and your wants. The money saved allows you to buy more of the other components you need. Fire away and enjoy.

Ok, lets set the record straight. I have made 6 XC brass using Paul Bike's form die set. I used once fired PMC 308 brass, once fired 308 Winchester brass, once fired 308 Chinese military brass fired in a machine gun, and New Lake City 308 brass '09.

Neck were turned. If memory is right, I use a .267 Wilson bushing in a set of Whidden dies. I have never annealed any of the brass, never had a neck split, and I figure I have .003 clearance on a loaded round.

All of the brass, and I mean all of it shot sub 1/4" brass in my Brux 30" barrel on a Stolle Panda action with a RAS Tuner/Brake on the end. This outfit shoots better than any of the dozen or more 6 PPC's that I have owned, but I have never put a Tuner/Brake on a 6 PPC. I have shot more zero's with this particular outfit than I have shot previously in all my life. I have shot the 105g A Max, 105g Berger Hunting, 108g Bergers with nodes at 39.5,40.5 g of H4350.

I made brass from Lapua 308 Palma brass, and remington 7 1/2 is hands down the most accurate, like night and day difference from CCI 450 with the 7 1/2 immediately shooting groups in the very low 2's and high 1's. I do use Wind Flags, sightron 10x50 scope. The Palma brass had a node at 3150 fps with the 105g Berger hunting with the H4350 and I got 900 rounds on 30 cases. At the end of my testing, I did an experiment with R#17 in the palma brass with the 7 1/2 with 42.5g of 17 at 3250 fps, shooting groups they were difficult to measure, even with a magnifying glass. Primer pockets on this 30 rounds of brass started opening up after the 4th firing, or the brass was getting tired from all the other firings. I pitched 13 cases, but the other 17 are still being shot, pockets are tight with 7 1/2's. I should have saved the 13 that I pitched and tried the larger dia Tula mag primers, but did not think of it.

I can not remember off hand what large rifle primers I use, will have to check my loading notes. and all large rifle primer brass shot in the 2's. The Chinese military brass only lasted two firings with the 105s at 3150.

Being a fan of PO Ackley, I remembered my old days of shooting the 243 Winchester and the 6mm Remington on p. dogs, Chucks, and Jack Rabbits. Shooting a load in the 243 Win of 36.5g of H4895 with 85g Sierra BTHP and with the 6 Remington, 38g of H4895 with the 85g Sierra bthp, the 6 Remington throat lasted much longer.

So, when I necked down the 308 brass to 6 XC, I had a neck that was .400 long.....Hummm...... I ordered a .275 Neck Reamer from JGS with a pilot on the front, and I cut the neck .400 long in the chamber, then throated ~.147 for the 105ish bullets. In 900 rounds of 105-108s doing 3150-3250 fps, the leade only grew .007, and the throat dia grew .0002 measured with reamer pilots on a grizzley rod. This is nothing short of amazing, to say the least with H4350 and R#17 the only powders used.

With a 6 Dasher, 6 BRX, 6 BRA, in 1100 rounds you have used up your best accuracy and by 1400 rounds, 9" in front of the throat is very well worn and fire cracked with the bore dia opening up .0022 at the throat.

Those with Ears, Let Them Hear! The long neck changed what PO Ackley called the "Interference Point".

I have a big box of Palma arriving this weekend to convert. Range brass is a good trainer for re-forming. I am of the school of thought that thinner necks will give more consistent tension on smaller sized bullets. The Peterson I have needs a hair under a thou skimmed to make them all even. Necessary? Probably not but I like to skim! My Tubb chamber has a .278 neck? Typo?

 

[AckleymanII]

If a guy cut a .400 long neck, had a reamer ground with .030 freebore plus leade angle, the bullet would be seated way back in the neck, never touching the shoulder/neck junction on the brass, giving even longer barrel life with the use of light and 105g bullets bullets. The 105's still will not get into the shoulder neck junction of the case, if memory serves me correctly.

There are not many experimenters anymore.

I am going to neck down and turn 500 Win once fired this Winter and another 500 new Hertenberger 308 brass, #5 taper to deer and hog hunt with will play with AA2700 which is one of the coolest burning powders on the market. The barrel should out live me.

In the 22 version with a long neck, barrel life will also be greatly reduced.

Be sure to re-anneal after forming. Didn't see that mentioned.

I annealed before to uniform 1x and then again after the final step of turning. Not for the impatient!

Yes. Correct. 278.

400 thou long neck. An obvious upgrade.

After building My 6 XC, SA SS "Lefty" Rem 700, Version ONE, Tubb Design & Criterion Chambered w/ .104 Fb barrel ( After much Study, I chose this, 6 XC Chamber Design ) I bought, Forster Dies and 200 pcs of, Norma 6 XC Brass, T'was,.. the "Easy Button" for me !
Then, since I had Hundreds of, rounds of, Win and Rem. .22-250 Brass, I decided to make some cheap, Coyote hunting "Throw away" brass,. Ahh,.. NOPE,.. BAD idea, in my Chamber ( the .200 Line, Got me ! )
Sometimes being, a "Titewad",.. ain't smart !

Why? What did you did, or not do, that caused this? Tubb has an article where he gives instructions of forming 6xc from 22-250. The 6xc parent case is the 22-250.

Read the Post, 6 XC ground truth as of, Jan. 2020 ( 10 Pages of trial and error, on 6 XC Chambers and, Brass ).
Serious "Frustrations" and confusion by, several Members !
After MUCH Study and asking questions of the better Known guys on here, I chose, the Tubb Design, Version One with, Norma Brass, but with, a Short Free bore for, the Lighter Bullets ( Sub, 110 gr's ). As I'm NOT, a 1,000 yd shooter.
@ Tesoro, I ran into, Neck thickness dimension Variations and, had "Clickers", so scrapped THAT idea, quickly.
Norma Brass,.. ain't that, Expensive. I'll stay with, what "Works well" for, Me.
And,. I will NOT,.. "Neck Turn", my brass.

Where is the post your talking about ? I’m on the fence of building a xc but it would kill me to have chamber/brass troubles
