But I have Stan's old Surgeon.....and can't you make it a sticky since it will be a popular caliber?

and Stan's load was:
107 SMK's
<span style="text-decoration: line-through">39.5</span> 38.5 gr H4350
Norma 6XC brass
2925fps



I'll see if it still likes it as soon as Frank at Bartlein sends it back to me as a 26" Tubb contour and Todd sends me the T2A its going in.

).

I have some nekkid Dtacs on the way to try as well.

Naw, the cool kids have been using the 6XC for years, its just now caught on with the non-HP guys. :)

Seriously though, I dont know how you guys are getting that Norma brass to run at 39+grs of H4350 without getting bolt stick. Shoot, we get stick at even less of a charge in the T2ks, especially if someone is running a factory Schneider (which is why I have a shelf with a bunch of them just sitting there, new). We have found that Winchester brass is much better with the pressure (if one chooses to run hot...which is something i dont do anymore) and lasts longer and is much cheaper.

Just getting going with the Lapua 22-250 brass and its showing a lot of promise. Not sure I like the blue box version as well as I liked their old gold box stuff (in other cals, of course, as they never made gold box 22-250). Its pretty consistent stuff and formed well. I have some with 4 firings so far and no issues.

My standard load is 38.0grs of H4350 with a 105-108 class bullet...nice and mild pressure but shoots really well with no bolt stick, which is a must as I use it for my 300 yard rapid fire load as well as 600-1000 yard work.

Yes, I can bump that up a bit, but why bother...it shoots great as is and a little extra oomph isnt going to make a significant wind difference and this seems to be a good accuracy node in my rifles/bbls (all T2ks, btw).

Out of a 26" Kreiger.

No bolt lift issues and another one of our team members (Regina) is running over 40gr and bare 115's with no issues as well.

John,

What are you doing for the brass prep?

Take 22-250 brass, run thru expanding mandrel, then thru 6xc die, then shoot in a reduced course match or practice, then deprime, SS media clean, then chamfer, size, prime, powder, bullet. No other brass prep. For HP/LR, works great. Might want to do more if F class or bench, or whatever, but I have no problems getting 1/2 MOA out of this process.

Re: 6XC Loads

Schneider barrels are soft and dont last. I've been running Norma brass in a Krieger barrel with almost 42 grains of H4350 on a 105 Berger VLD at 3040 FPS. and my Krieger 8 twist has over 3K rounds thru it with out bolt lift/camming problems. When it comes time to spin a new barrel on I have 3 new 7 1/2 twist Bartleins in the garage.
 
#12
Re: 6XC Loads

42grs of H4350 and a 105?! wow! I ran 41grs in a Kreiger with the same bullet for a while but was ruining brass so I scrapped that load. Now, I just run some sane loads and try to make up for the lesser speed with better wind skills. Sometimes it works, sometimes, well, sometimes you get a 9. :)

PGS,
I am not a 6xc guy, but I am a H4350 fan. So I was wondering why you are running a winter and summer load. I personally have not found the need with most/if not all the extreme powders to run separate loads,but that's me. Did you run into accuracy problems or pressure? I am very interested to hear your response. I wonder if the cartridges that I run 4350 in just happen to not show what yours are.

Must of got some of that fast H4350 going around... Guess I need to buy another lot.

Re: 6XC Loads

I am trying Berger 105 Hybrids in my 6XC. Looks very promising so far. During OCW load develpoment today I had two groups right at 1/2" at 200 yards. I will update as load development progresses.
 
#21
Re: 6XC Loads

Mudcat, what is your opinion on whats wrong with the Gary S. Barrels. I have one on my T2K and needed the chamber polished by Tubb to get the brass to not stick at moderate loads of 4350, but it seems better now.

What other barrel do you like for the t2K in 6XC?

If you have a bunch sitting around that are factory T2K GS barrels how much do you want for one or 2?

Thanks

Patrick

Re: 6XC Loads

Update on my 105 Hybrid load development. My latest round of loads gave me a 5 shot group of 5/8" at 200 yards prone from a bipod. But 4 shots were 0.45" center to center. I am using Norma brass, CCI 200 primers and H4350.

Re: 6XC Loads

I got bored with the 38.1 gr of H4350, 115 DTAC BN & Wolf primers. I switched the barreled action into a new stock & just decided to try some new loads. 115 DTAC BN & Wolf primers. With RL 17 I didn't find a load that would shoot better than the H4350 load. On a chance I tried some H100V. It turned out that 40.0 grs. H100V turned in slightly better accuracy @ 400 years than the old stand by H4350 load. I am going to try this load at this weekends 400 yard group/score match. While I didn't have the chrono at the range the H100V load hit about 3" higher on the target @ 400 yards than the H4350 load.

Re: 6XC Loads

Ooops! Sorry for the fat fingered mistake. I was trying to load for the match last night & the brass was not cooperating. I ran out of time & had to go with the old stand by load of H4350. I was able to manage small group (5 shots) in my class, BR which was also good for small group of the day of 5 1/2". I will get the brass problem sorted out & do more testing at 400 YARDS.
Accurate Ordnance put the rifle together.

Re: 6XC Loads

I'm having some amazing results with RE-17:

Rem 700 SA Blueprinted
28" Lilja 1-8" twist

Norma Brass
Wolf/Tula LR magnum Primer
115 DTAC coated in Tungsten Disulfide/WS2/Danzac
Seated at the lands .000"

39.5 Grns:
1 - 3089
2 - 3084
3 - 3087
4 - 3086
5 - 3078
6 - 3083
7 - 3089
8 - 3079
9 - 3084
10 -3083

39.7 grns:
1 - 3141
2 - 3145
3 - 3149
4 - 3140
5 - 3144
6 - 3145
7 - 3148
8 - 3139
9 - 3147
10 - 3144

The SD's and ES's are pretty amazing to say the least. Powder charges were done to 1-2 kernels of accuracy every charge, as I invested in a scale that will measure to +/- 0.01 grains. These were all done in 5 shot groups. I had two groups in the 0.4's one that was just over 0.34" and my best was 0.281" all measured CTC. No sticky bolt lift or ejector swipe. When I ran initial pressure testing for Reloader 17 I went all the way up to 41.5 grns before I saw ejector swipe, that was giving me 3275 fps! RE-17 could be a game changing powder for the 6XC. My only concern is that it is a double based powder, and I've been shooting it in the winter time between 30F-50F. I guess we'll see how it does in the summer.

Note - Do not duplicate these loads unless you are coating your bullets with WS2. WS2 is 5 times slicker than Boron Nitride and about 3 times slicker than Moly. Please keep that in mind if you're going to try and duplicate any of these numbers.

Sorry, just now saw this post. Not sure on the bbls other than they may be soft, as already mentioned (I note that when I have removed them my bbl vice will mash them up pretty good and that NEVER happens with my other brands) and might have something to do with how they cut their chambers. BUt, thats speculation and thats all the further I have went in figuring it out cause I just refuse to use them. On my XTC rifles, I use WOA bbls (they are good, and if you didnt know the brand was Wilson, you couldnt guess it by how they shoot) and for LR, I usually use K, L, B, B, or RC.

I have a bunch of factory GS bbls, but as they are numbered to our rifles, I dont part with them. Some day, if we sell the rifles, we might just put them right back on for the departure. :)

Re: 6XC Loads

I have the older school 6x, but shouldnt the loads be the same? I have loaded a dozen 87 vmax. 35 varget at 2.59" OAL. Anyone try these? This light load is capable of 3200+, good out to 400 before it kicks its own ass.

My 105 and 107 loads are running a very mild 32.5 grains. Trying to extend my barrel life. Is everyone seeing tighter groups pushing them to the upper limits?
 
#31
Re: 6XC Loads

For my 105 Hybrid load I have settled on 40.7 grains of H4350 in Norma brass with 210M primers. Velocity is right at 3100 fps. Rifle is a 700 action with a 1:8 twist, 27" Bartlien barrel. In a 200 yard match I had the best group of 0.32 MOA for 5 shots. I was shooting prone from a bipod.

Just for grins I am about to try some 107 SMK's.

Re: 6XC Loads

I run 38.5 grains of H4350 under a 105 Amax. I get sub 1/2 MOA 5 shot groups consistently. My velocity is right around the 3000 mark. I played around with RE17 when I first got the gun and could push it to 3075 but I didnt like the temp sensitivity. I plan on trying some Accurate 4350 in a few weeks. I would really like to try out a ball type powder.

Anyone have any luck with ball type powders with the XC?
 
#39
Re: 6XC Loads

I tried some h100v. 40gr gave me 3105 according to my magneto speed. The velocity is definitely there, but accuracy wasn't.

I settled on 40grs of 4350. (105 hybrid) 3083 average f/s. SD of 8. Accuracy is amazing. Took it all the way out to 1000 yds with amazing results.

Where do you get your brass from? Tubbs doesn't have it listed on his site and everywhere that might have it is out of stock with no date for restock. I am going to be running a 20" Benchmark 1:8...

Brass is tough for the 6xc....it's either David Tubb, Midway or Bruno's.

The brass at Midway comes and goes pretty quick, but I've scored some recently. And give Tubb a call, he's got some coming in shortly, and his is $0.88/piece.

-best of luck!

For what its worth i have a 6mm madman. Only real difference is OAL which is .050 shorter then a XC. If I neck turn XC brass it works but when the rifle was built the XC wasnt known about(at least not by me, 2002). Winchester 22-250 brass is quick and easy. I neck mine up to 6mm. Neck turn then run it thru the sizing die. Prime it, then dump 15 or so gr of accurate 5 in it, pack it with flour(using a small straw) til its full, then cover the end with crisco and shoot it. Other then a cloud of flour in the basement and a dirty rifle the brass is ready to go. I have a 8 twist pac-nor 26" on a blueprinted rem 700. Best load was 41.8gr of N165 with 107 SMKs. Around a 2" group at 600yds with considerable conditions is common. Been trying out 115 DTACs . But still in development. Along with 105 Berger Hybreds, but I dont have any place very close to actually stretch it out. Hope its helpful!

Is there a consensus on the norma brass is good enough for the price, or is 22-250 brass the way to go?
Click to expand...

I prefer to use Norma brass in my 6XC but win brass will work.
The only thing you should be aware of when using win 22-250 brass in your XC is that your reamer should be setup for the win brass.

The win brass is .462" at the base & both batches of Norma brass I've measured is .469" at the base.
A friend used some reformed win 22-250 brass in his rifle that was made using a reamer setup for Norma brass & he had some case head separation issues due to the excessive clearance.
A Norma chamber reamer is approx. .470" at the base
