6XC Guys

[barnjoer]

Any ideas on the 115 Berger VLD Target bullets through A 1-7.5 30''/ running 38.5 H4350 at 2980fps. I get 2 shots at 1.5" at 1000 then get A flyer that is about 8" out. Any ideas??

115 dtacs instead... berger 115s got issues in the 6XC so I hear... I almost tried it too, but got steered away from it..

 

[Sniper338]

I run a 7.5 twist 6xc and 105s... its fabulous.

115 dtacs are great with a 7.5 twist too so I hear.. havent tried em yet.

Havent heard big stories on the 110smk yet... some guys say they are going to try them here, then never come back with results...

Every time I look for dtacs no one has any!
I have 500 115 Bergers in hand. That why I am using them.

I have shot A 5 shot 1/4” moa at 1000 with the 115 bergers, just don’t know what is going on now with it. Gun has 115 rounds down the barrel.

Yup. Thought about this too. Any input on accuracy while fire forming brass? Ideas of barrel life?[/QUOT

From what I have been able to find barrel life would be about the same but the longer neck could yield a longer life? Brass forming is run Winchester brass through the die and go shoot. My interest is less work making brass. Winchester is about 1/2 the cost of Lapua so even if the brass life is shorter still less money and time. Lapua brass for the 6SLR would still require neck turning so could be done. I prefer to shoot vs brass prep. The Norma 6XC brass was ok but some pockets were loose after 5 firings and Labradar showed 50fps reduction vs snug pockets. Have the 6SLR die and reamer ordered but no first hand experience.

You asked a while back but ill have a go...Im on my second SLR now, had this one up and runnig a tad over 2weeks now and formed 50pieces of brass with 105Hornady Match, 105Nosler CC and 105Berger HVLDs jammed hard into the lands with a "start" load rite at 3000fps. At 110y 5 of each of those bullets (15 in total for the group) aimed at the same spot shoots well below 1/2" with the VLDs and Hornadys going into a little over one hole with the CCs opening the group up. Anything I have shot in it just shoots, I ran a string last week to see where my speed/preasure maxed out and n had coated105s HVLDs going just about 3300fps (28" barrel with a powder thats basically 4831sc) without any problems. If i had the balls I could probably get 3350fps or more, with the load im going to test at 800y now the ES is running around 3fps (coated 105HVLD @3150fps), imo a fantatsic calliber BUT I wil not shoot Winchester brass or anything other than Lapua in it and thats where the drawback comes in compared to the XC imo. The amount of work you have to put in to get the Lapuas just rite is realy allot of work but for me its worth it and when this barrel dies the next one will also be eating SLR brass. Obviously you can use Win and Remi brass but the amount of problems I had with the brass in my first rifle was crazy and just when you have a 100 pieces sorted, fired and a load that works primers would leek al over your boltface.

I’ve also had good results with 105 Hybrid on deer. In the past few years I’ve used them on deer out of 6x47 Lapua, 6 Creed, and 6XC.

Out of the 3 which is your favourite?

 

[USMCDOC]

Looking to possibly switch calibers while troubleshooting an issue with another 6. First round build was a toss up between the 6x47 and the 6XC. A new chamber is in my future either way, so I think I should rehash this. Seems like these are inherently accurate and there's a simplicity option since factory brass is available.

For those using the Norma XC brass, how many firing are you getting and with what load?

Any disadvantage in going with the 6XCII reamer? Works well with other brass (would have to form of course) besides the Norma factory?

Dies that are working well with the XCII reamer?

Any input on Whidden hydraulic dies in The 6XC?

Should I be considering the 6 Creedmore as well since factory brass is available? PRS rifle, so I need to keep the speed under limits.

Would like to shoot 105 to 110's over 3000 in this, barrel is a Brux 7.5 twist.

Really appreciated gents.

Ever heard of the 240NMC?

 

[Clucknmoan]

Ever heard of the 240NMC?

Nope!

 

[USMCDOC]

Nope!

Randy Gregory and Steve Knutsen came out with the 240NMC before David came out with the 6mmX. The 6mmX is the one that had the 20 degree shoulder because it was originally a .243 shortened .132 and using 22/250 brass.
{This is what has lead to the 6XC II}
Then David came out with the 6XC which has a 30 degree shoulder.
The 240NMC has a 28 degree shoulder, which is the same angle of the 22/250. The 240NMC is the same over all length of the 22/250, but when fired formed.. it changes to a 28 degree shoulder with a .308 body taper, the 240NMC has more case volume, but a shorter neck than the XC... On the 6XC the shoulder has been pushed back slightly to get the longer neck.

Guys using Norma brass...anyone own the reamer? I've heard Norma brass can cause some issues with the older reamers.

Good info, keep it coming.

I have had (5) 6XC rifles. Did not own my own reamer so each one was cut with a different reamer. The problem is that there is no real standard for the 6xc. I eventually got burned by having a chamber cut with an early model reamer (small base for 22-250 brass) and it would not work with the Norma brass. I now am the proud new owner of a 6XCII reamer and have not yet shot the barrel with the 6XCII chamber. However, I bought the 6XCII reamer and die set so I know everything will match.

Before buying the 6XCII reamer, I considered selling everything and going to the 6-creedmoor instead. A look at the 6XCII and 6-creedmoor reamer prints will show you that the two cartridges are virtually identical. I decided to go with the 6XCII because I already have a ton of brass and did not want to swap it out for a different caliber. They are almost IDENTICAL though.

Good luck,

-Trevor

I just can't bring myself to own anything Creedmore. Nothing against the cartridges, it's the majority of the crowd that owns them around here that I can't being myself to be apart of...lol! A few guys own them for the right reasons, but mostly for the name.

Whidden has fixed the issue of deforming bulltet tips

 

[rancher5]

115 dtacs instead... berger 115s got issues in the 6XC so I hear... I almost tried it too, but got steered away from it..

I have a Shilen 8twist for bullets over 100gr, no clue what make it shoot >100 grains verses just the regular 8 twist, anyway it shoots the 115 closed tip boride Tubbs bullets GREAT easy grouping bluets " influenced by the wind consistently" very consistent out of my 24" barel 8 tw using 39.2 gr H4350 seated .005 ITL Freebore is .130, .275neck after ignition, Tubbs DTAC is longest bullet Ive found, which helps being the Freebore is long

 

[Goldenfinger]

The 110's do NOT need a 7.5 or even 7tw to stabalize. I've shot them into -2400 DA out of an 8tw with zero stability issues.

The problem with the 110's is the random fliers being found. Especially in the newer lot of bullets. The originals that came out were amazing. Majority of shooters are finding horizontal plane fliers consistently. Sorry, I know this wasn't about the OP

 

[Clucknmoan]

This is good info for the OP. I am wanting to shoot the 110's once this all gets worked out.

Ordering a reamer this morning, I'm going with the 6BR Ackley instead of the bigger 6's.

Keep us updated on your progress after you get it chambered.
