Please list your TWELVE twist success or failure stories in .223 Rem with these
As long as we're on the subject of .224-based centerfires and largish game....
Please list your TWELVE twist success or failure stories with these factory rounds or bullets. Just interested in 1 in 12 twist anecdotes for these bullets / factory rounds, and which rifle, barrel length, and other details - do they stabilize and shoot well - or not: 1. Federal Fusion 62 gr (mostly interested in this one) 2. Federal 64 gr soft point 3. Nosler 60 gr Partition 4. Winchester 64 gr Power Point 5. Federal / Speer Trophy Bonded Bear Claw 62 gr (discontinued apparently, or LEO only now?) 6. Remington 62 gr Core-Lokt UB-PSP 7. Barnes 53 gr TSX 8. Barnes 55 gr TSX 9. Hornady Superformance 55 gr GMX Any other 60-65 grain lead or 50-55 gr gilding metal bullet (excluding FMJ / military ammo) I didn't list the Nosler 64 gr Bonded Solid Base because the answer is definitely yes, as recently discussed on here - even in 14 twists. I will start. The Weatherby Vanguard I Sub-MOA Varminter shoots the 62 Federal Fusion great. Last edited by Unlicensed Dremel; September 5, 2014 at 10:51 AM. |

A 223 with a 1:12" twist will not generally stabilize anything much over 55 gr (unless it is a short round nose or semi-spritzer bullet). It has pretty much the same limitations as a 1:14" twist except you can stabilize 55 gr spritzer BT probably a little more reliably. I shoot an older Interarms Mini-Mauser in 223 with a 1:12" twist, it does well with 55 gr flat base spritzers.

My only 12 twist is a Remington 788 which I don't have any record of ever shooting with a factory load.
It did very well with handloaded Berger 60 gr flatbase HP. I never pursued it much, Sierra 52s and 53s are so much easier to get. |

another Mini Mauser 1:12
My mini-Mauser shoots well with reloads using 52/53 gr SMK's. Surprisingly, at 100 yds anyhow, it will plunk 3 Remington 62 gr factory match rounds into MOA groups nearly as tight.
What does not shoot well are the assorted 55 gr FMJ's, as well as W-W Ranger 55 PSP's. In fact a lot of .223 factory ammo quality seems all over the map, in that rifle, and our AR (1:9) as well. It shot Federal 55 gr bonded tactical loads into hunting size groups, about 1.5 MOA good enough for bamaboy to take it deer hunting in his early jaunts. |

My 12 twist, Remington 700, .223, shoots Nosler Partition 60 grainers to 1 MOA. I know better than to invest in any bullets heavier than those.
Haven't tried the Hornady GMX 55 grain bullets, but if they stabilize, I'll probably load a bunch for larger varmints and game. The non-lead bullets are longer than equivalent lead-core bullets, so there's a question of stability, since it's more a length issue than one of weight. |

Scorch, right - I understand - except that they do often. At least, there are many reports, for example, of 62 gr Fusions shooting well in 12s - a lot more than reports of them not shooting well. So that's why I'm trying to flesh out a little here - where that line might be with various rifles, chamberings, bbl lengths, and specific bullets.
I mean, look at all those I listed - are those ALL made for AR15 guys? Maybe, but I kind of doubt it. Tikka and some CZs and some Savages notwithstanding, the vast majority of .223 non-ARs sold have 12 twists. *Somebody* keeps buying these rounds and bullets - presumably because they shoot well. Maybe it is all AR15 guys, but that's what I'm trying to find out. Last edited by Unlicensed Dremel; September 5, 2014 at 10:48 AM. |

The 55gr GMX is reportedly 0.898". The 62gr Barnes TTSX is 0.981 and Barnes says it will stabilize in 1:12.
My only point of reference in that Barnes said their 80gr .243 TTSX would stabilize in a 1:10 when every stability calculator says it would not or would be marginal. Barnes was right, which isn't terribly surprising as I assume they've actually DONE IT. Therefore, I assume that they're also right about the 62gr and, if they are, the shorter and lighter GMX should be basically the same.

http://www.barnesbullets.com/product...le/tsx-bullet/ The 53 and 55 are flatbased, and the 62 is a boattail, so it makes sense. |

Here's a 12 twist success story but with none of your bullets. My buddies son when he was 8 went to TX to hunt and used a Handi Rifle with a 1:12 twist. My buddy tried the Partitions and 55 grain TSX and couldn't get them to stabilize so he settled on the 45 grain TSX.

Very nice. Those TSXs are impressive.
And you have to wonder why Barnes made *both* a 53 gr and a 55 gr? What's 2 measly grains of difference gonna do? |

I can't remember which is which, but one was intended for general purpose use (bolt actions and single-shots), while the other was intended for ARs.

Nosler 60 grain Partition worked in 1-12 both 223 and 22-250(groups not as tight as 55 and under)
Hornady 60 grain Spire Point = same Win 64 grain, PMC 64 grain=total failure(3-4" groups or worse) Oddly enough, the Speer 70 semi-spritzer will produce 150 yard deer hunting accuracy in rifles that won't handle the 62-64 grain bullets. |
