I could be wrong, but I doubt the 224V pushes those weight bullets a whole lot faster than the 5.56. I believe there is only a couple grains difference in capacity. I would imagine the 22 Nosler would be a better round for pushing the light bullets faster. View Quote View All Quotes View All Quotes Quoted:

I think a fast twist would be great for the heavier bullets but I personally would also like a 1/9 twist so I can shoot the 55 grain bullets as fast as possible and occasionally shoot 77 grains or so. I would of course get both . |

I don't blame anyone for waiting, even though from what I'm seeing so far, performance is going to a little better velocity wise then most are expecting with the 90's regardless of barrel length someone might choose. The Sierra Matchking 90 grain might be a sweet spot for overall length versus powder charge and velocity..... The 90 grain SMK being .06 shorter on average then the Berger 90 grain VLD.
I've been holding off buying 95 grain SMK's, at least until I see somewhere that someone comes up with a magic recipe to make up for what I'm thinking will be a pretty big velocity loss compared to the 90 grain SMK. I doubt the increase in BC will make up for loss in velocity when it all balances out in the end. I found a link where a few people took measurements from the 95's, no happy medium. Measurements jump around from 1.293-1.304 inches long. That's a pretty huge increase in length compared to the 90 grain SMK at 1.165 inches long. I test loaded a batch of 90 grain Berger VLD's(1.225 average projectile length) loaded to 2.280 COAL. They felt like they were slightly compressing the powder, the 95 grain SMK's being around another .07 longer then the Bergers are going to mean something has to give. ASC mags only have another .015 or so of reliable length you can squeeze out of the COAL. I was loading with PP2000MR off of their published data, just going a little longer for both the 90 grain SMK and Berger VLD loads. A link to the thread if anyone is interested in reading it. Accurateshooter thread If Federal did their homework, and the 90 grain SMK is the best all around performer at long range currently available, there might be no great need to switch from a 1/7 as it is well into the optimal stability range. Like I said, I don't blame anyone for waiting, I enjoy screwing around and experimenting. This is far from my only AR, any rifle that gets me out shooting is a good rifle. |

I’m really curious to know why the calculator look good with 1:7 twist but Sierra says 1:6.5. Anyone got an explanation from Sierra?

Until there is a lot more data out there on 1000y performance from many shooters across many barrel lengths/manufacturers, it's likely that the jury will remain out on optimal twist.
Unless the developers have been doing a LOT of homework on trying to introduce variation in rifling profiles and check long range stability with different lengths, a variety of pressures, and during all seasons at both low and high elevation, it's very possible that a slower twist that prints lovely groups at 200y with 90's will have an unacceptable rate of stability failure at the distances that this cartridge is being marketed for (800-1200y). Especially when many, many users will not want a 24" truck axle. Short is in, and I think the V developers turned a blind eye to that. Problem is, industry wants to provide speedy light bullet loadings too for marketing diversity, and the 6.5 twist or faster might shred a lot of varmint bullets. But why the hell shoot light bullets in the V, when .223 already has that handled? They developed a niche cartridge here, but if they don't stick with the program, the industry will have produced a lemon in the market's eyes after people have spent a couple of years fiddling with it. Things will be ripe for the 6mm replacement ;-) Classic case of marketing expectations meets reality, but that's none of my business /kermit |

I honestly think the 6.5 twist rate disclaimer is based on lower velocities. The calcs I ran on the ballistic calculator shows problems with lower velocities but over 2,400 FPS the 1:7 has no issues that I see. I’ll let someone with more experience confirm this.
Based on YouTube videos Guns America shot 1,000 yards then one mile with a 1:7 twist. CMMG did 1,000!yards also. Another shot 800 yards fine but there 1200 yard gong was covered in snow. |

Interesting email quoted elsewhere from JP Enterprises talking about their first run of barrels not coming with typical accuracy guarantee when using the 90gr 224V rounds, and that they will be addressing that in next batch and giving those on preorder option to wait or take barrel from first batch.
Anyone receive this email directly? |

From Johnny's Reloading Bench where he's using a White Oak, 18" 1:7 with a rifle length gas system. He's discussing his reloading attempts using the Sierra 90gr SMK. It's a long video, almost an hour, but he's trying to work with the Sierras, which are listed at a 1/6.5 or faster. He starts shooting at around 41:40.

Hmmm, so they tooled up for and added a specialized bullet to their lineup that required a bastard twist their customer base likely didn't own.

I have never been deep in the long range game but I am pretty sure that Sierra has been doing a 90 before 06 but am not sure since I don’t know anyone that uses them. Seems like high power and some occasional wildcat weirdos were the only people I ever saw talk about them online.

I put my order in for a Criterion barrel a while back and had an expectation of a mid March delivery. Well I get a call yesterday saying the 1-7 RH twist won't shoot the higher grain ammo like expected. Apparently they went back to the drawing board and they are going to have to make a 1-6 or 1-6.5 twist. Has anyone else heard anything about this? View Quote |

.224" Diameter 90 grain HPBT MatchKing In response to the increasing demands of Long Range shooters, Sierra is pleased to announce the introduction of the newest member of our MatchKing line; the 22 caliber 90 grain HPBT. With the recent successes of the AR-15/M16 rifles in Long Range competition, the need was felt to maximize the ballistic potential of these rifles. The new 90 grain MatchKing is the final product of a series of tests, covering both accuracy and exterior ballistics, to arrive at the best possible bullet for the Long Range competitor. Designed specifically for the .223 Remington/5.56x45mm cartridge, the new 90 MK is at equally at home in both Match and Service Rifles. Due to the inherent requirements for a bullet of this type, the 90 grain MK is intended for single loading, and is not intended to be fed from a magazine. Sierra recommends the use of a 1 x 6.5" or faster twist for optimum stability and performance. Available in the summer of 2005, these bullets will be available in boxes of 50 bullets (stock #1490) for $13.85 per box or in boxes of 500 bullets (stock #9290) for $111.80 per box. You may contact Sierra Bullets by e-mail at [email protected], call the toll free Sierra number at 800-223-8799, or visit our web page at www.sierrabullets.com!! Above 1750 fpm the BC is over .500 which makes the 223 excell as a 1000 yard caliber. |

I certainly support any individual's pursuit of a particular weight bullet to a given platform, but I thought the big plus and benefit of the .224V was heavier bullets at high velocity. We are talking in the AR15 platform here, and getting light bullets to haul buns in a 5.56 or Wylde chamber works pretty darned well. My 20" AR barrel can push 55g'ers at 3200-3300 fps. I'm not up on all the ultimate performance of the .224V, but is it really worth the pursuit for the super light bullets? Asking, not making a claim/statement.
I understand choosing specific twists for narrow application. I have a 1:10 carbine gas 16" 300BO just to shoot 110g bullets that I load supersonic...have a 9.5" pistol gas 1:7 twist barrel for 208g home loaded subs only. I'm just curious if the .224V is worth the effort over the 5.56/Wylde for light bullets. I see little doubt when it comes to the heavy bullets. |

View Quote be loaded long, beyond magazine length, for the Slow Fire Prone stage at 600 yards where you have to single-load. It never really was super popular in my experience, due to needing a fast twist barrel. Plus, it's so heavy its difficult to really drive them fast enough from a .223 Rem or 5.56x45mm NATO to beat its lighter competition. I never made the switch and was happy shooting 80 grain Bergers at 600 yards. A good point has been made in this thread regarding whether the Valkyrie can actually drive the new 95 grain MatchKing fast enough to make use of its potential. It might not be able to unless you got to a 24 inch barrel. 90 grains may be the sweet spot... |

I push 130's. i knda favor right below the big pills to make it......simpler.

I would surmise 1:7 was found to be suitable for the 90gr SMK at sea level.
Whether that will hold true for the 95gr, and presumably heavier bullets that might arrive later, will remain to be seen. There's also the idea that a bullet leaving the barrel with a higher rotational speed will do better at distance. Over on Snipers Hide there are a few threads discussing this in the ELR section. If this is true, I would want a 1:6 if pushing the long/heavy bullets to their extremes. I'm still holding out for more first hand data from non-manufacturers before jumping into the 224V. |
