How often would you say you notice the flickering with the MK6? Does it happen often?

To be fair though, comparing the 6mm 105-107gr vs 6.5mm 139-142gr bullets from the same manufacturer, the 6mm bullets are about 10 cents per cheaper, which help offset the shorter barrel life. The total cost seems to balance out pretty evenly.I agree that if you're not reloading though 6.5 Creedmoor is the way to go even though on SH they're reporting recent lots of Hornady 140 Amax factory ammo have had poor performance.

gseven has a truing function. You have to create an online account though. Here is the url: http://www.gseven.com/ballistic-program Also, if you have an android smartphone you can use Shooter or the Applied Ballistics app, among others. They have a truing function as well (the Applied Ballistics truing is supposed to be more advanced).

Awesome! I hope the loads work for you. About the case capacity, with Varget you're going to have a compressed loads if you're using a decent charge. It's fine as long as you don't have something like a Redding Competition Seater which is known to break if you're constantly seating bullets on compressed loads. I'm sure you'll find a good load really quickly, those are popular components for good reason. Varget just doesn't give you as much velocity as other powders might in .223 with the heavies unfortunately. Still good, just not great. Hopefully you can make it out to Woody's then for the second practice day in late June or at least one of the matches. They're a blast!

That's a really nice gun. It should do very well at the DMM as long as you have good zeroes and the wind isn't blowing a ridiculous amount. Like you stated earlier though you'll probably want a different scope that's more suited for precision shooting. Are you getting the Hornady 75 BTHP's? Those are nice bullets, especially for the price. Any charge with Varget from 23.8-24.5gr (I've heard the factory Hornady 75 BTHP Match load is 24.1 Varget and a 75 BTHP) will do great out of your gun I'm sure. As to whether or not the Bergers will be better it's hard to tell until you shoot them both out of your gun. The twist rate is fine for them, but your gun just might not shoot the 70 VLD's as well as the Hornadys. If that's the case they're probably not worth using even though the exterior ballistic performance will be better. Especially factoring in the increased cost of the Berger bullets. Did you sign up for the practice day at Woody's? It's next month and would be a great chance to get some practice and zeroes for your gun if you don't have regular access to a range that offers extended distances like most of us.

Yeah the PRS matches seem similar to the DMM (I'm only going from what I've read, my first PRS match will be the upcoming match at Woody's) but they're points-based not time-based so hits are a higher priority. PRS matches also have smaller targets, farther ranges (like you mentioned), much more movement, and they can test additional rifle skills such as movers, loopholes, angle shooting, and much more. Just a lot more precision-oriented. If you're talking about an AR15 with a 4x Burris I'm going to guess it's a 16" barrel. That would probably work moderately well with faster loaded heavies (especially if you can get Berger 70 VLD's to work in your gun, same BC as the 75/77's but with a higher velocity) and a better scope. Your AR10 would probably be even better since it seems more accurate. And although .223 can have a similar trajectory to .308, .308 will drift less (with the same barrel length and comparable match ammo) at the expense of a higher cost and recoil. That being said, we just used AR15's and we finished OK at the match but like I mentioned people have fared much better than we have using AR15's as well.

I believe he's talking about the Designated Marksman Match at Woody's (http://woodysmatch.com/) in North Carolina. You shoot 6-12" steel targets over natural terrain from 100-600 yards on the clock from field positions. It's not just shooting targets located on a berm. It's a great match and really well-designed and well-run. For sure a great time. Shooter Steve, if you were wondering if you could be competitive with an AR10 at Woody's DMM it would probably matter how accurate your gun is with match ammo. If it shoots about a MOA for sure you can be competitive, IMHO. People have won the match shooting AR15's in .223.

What kind of barrel life are you getting with this load out of the 6cm? Pushing them to 3,200 fps about 3,000 rounds. Maybe a little less. Throttle it back to 3,000 fps and 4,000 round barrel life is about the norm. I pulled my last barrel, a Brux 8 twist, around the 3,500 round mark. It still had plenty of life left in it but I didnt want it to possibly die in the middle of the season. Great info, thank you.

What kind of barrel life are you getting with this load out of the 6cm?

There's a thread in the scope section of Sniper's Hide about the new Razor HD Gen II 3-18x50 and 4.5-27x56. Also updated reticles for the 1-6, a MOA reticle and a mil one.

It's fine, it just isn't as fast as other options like the Versamax with a much larger loading port. Also, before I had my loading port opened up and beveled, the second shell tended to get caught when I did load two.

Our 16" (DD LW barrel, 12" DD Lite handguard, CTR stock) is 8# with an Aimpoint T1 and loaded 30rd USGI magazine. With the Vortex 1-6 in a Larue SPR mount in lieu of the Aimpoint, it's 9.6#.

Are all these weights unloaded?

You can with the standard NC-1 free float tube. I'm pretty sure you can't with the small diameter free float tube but not 100% sure. It looks to be a little over 1.8" ID.

I haven't had very good luck with a couple BCM chrome moly barrels I had (non BFH). They would only shoot about 2moa with 75/77 match ammo and a bit worse with 55 fmj's. I've had good results with Noveske, RRA, and Daniel Defense 14.5/16" barrels. They shot both 55's and 75/77's well.

I'm shooting a 20" WOA 1:7 barrel with thousands of rounds through it and have been trying to use up the rest of my Winchester 748 developing a Hornady 55gr FMJ load for it. I settled on a 27gr charge. For some reason, I'm getting a couple fliers per 10 shots. I still need to test the load further but I'm somewhat pleased with the results for now. Even with the two fliers this 10 shot group from 100y is still about 1.25" but the main group is smaller.

Have you also shot any 55gr loads through your Criterion? If so how did they do?

If you're talking about the .22 conversion bolts and not uppers, we've had good luck with our Target Master .22 bolt conversion (which uses BDM mags). I don't recall there being many malfunctions at all. I do know some people at our club had issues with CMMG conversion kits and they seem hit or miss. As far as accuracy is concerned, I'm almost certain you won't be able to match the accuracy you get out of your dedicated upper. I got between 2-2.5" groups at 25 yards with Fed Bulk Pack out of our Target Master kit, which sounds pretty bad but it worked pretty well for Ruger Rimfire at the club level. Also, I wouldn't be too concerned about the supposed leading in the gas tube from using a conversion kit. We've shot over 1200 rounds of .22lr before "clearing it out" with .223 and it was fine.

The Vortex is heavier and has a stiffer magnification ring but has better illumination, fov, and glass quality imho. It might be worth considering whether you have a preference for a horseshoe type reticle like on the Bushnell (or donut on the ffl model) or a dot like on the Vortex. Also the BDC lines match up better on the Bushnell for nice even yardages (300, 400, 500, 600 yards) with 16-18" barrels not shooting especially fast ammo. I'm not sure exactly about the Vortex but I've heard the ranging on the Bushnell, with the width of the BDC lines corresponding to torso width like on the Acog, is not very accurate.

IMHO, I don't think a dedicated high power rifle from those manufacturers would be good for both high power and multigun (since you said you wanted to try 3gun with it). A purpose-built service rifle will have sights with such a small aperture that shooting at speed with them will be difficult. Sometimes, if it is dark enough outside, just seeing through them is difficult. Also, to get the rifle to balance well, settle your position, and minimize muzzle movement, lead weights are added to the stock and sometimes under the handguard as well. This is on top of the steel free float tube, all of which contribute to make a pretty hefty rifle. Mine are around 14.5 pounds, unloaded. Without adding any weight in the stock or under the handguard, you're probably around 10 pounds, but it will be feel quite muzzle heavy. Another route would be to build your own rifle. CMP matches now allow 12" quad rails instead of usual A2 handguard look. NRA matches still AFAIK require that A2 handguard look with the free float tube underneath. If you decide to build a service rifle under CMP rules, that is an option. At NRA matches I believe you will just shoot under the match rifle class. If you want to go the quad rail route, you still need a 20" barrel and a front sight base. However, this means you can have an all-around lighter more balanced rifle that can do moderately well at both HP and 3gun. It won't be optimal for either but it'd be a pretty nice compromise, in my opinion. Pretty much the most popular barrel to get will be a White Oak Armament barrel, you'll probably want to get the pre-ban version. I don't think anything but an A2 flash hider will be allowed in HP, but if you decide to shoot more 3gun you will have a barrel that can accept a muzzle brake. With a 20" stainless barrel, rifle gas, and A2 flash hider the rifle will shoot kinda softly already (obviously not nearly as softly as with a brake though!) so it should be somewhat serviceable for 3gun. Another important thing to get is the flat top upper. This way, if you want to shoot an optic in 3gun (or even in NRA HP as they now have an any rifle/any sight class) you can. The only thing that might be slightly annoying is the front sight @ 1x with a low power variable scope. I know this somewhat bothers me but it doesn't many people. There are a few options as far as carry handles go, but if you decide you want to try shooting 3gun with iron sights, there is the WOA carry handle (pinned is extra). It will have more than enough elevation to get to 600 yards, but the nice thing is that it will accept different size apertures. You can ask WOA for their largest aperture size, and if it still isn't large enough to acquire targets quickly enough in all lighting conditions, you can drill it out a bit. That way you can still use the smaller aperture inserts for HP. If you think you might want to use optics for 3gun and stick with the carry handle for HP you can try the RRA NM carry handle. It doesn't have the different size aperture inserts so it isn't as versatile as the WOA. But the selling point is that it is cheaper. It also has more than enough elevation adjustment to get to 600 yards. If you feel like you want both the versatility and performance, you can always step up to the WOA pinned carry handle. It's expensive but it's a very nice sight. All this is just IMHO and YMMV.

Our Noveske 18" SPR (stainless barrel) upper shoots an honest MOA with new 55gr FMJ Federal American Eagle, the stuff in the black box or bulk pack (AE223BK). The older lots in the red box, not so much.

What does the width of the horizontal lines on the BDC correspond to if anything? Is it similar to the ranging mechanism on an ACOG?
