I'm looking for load info for the 6x45. Does anyone have links or tables of reload data for it?
Also, I would like to know whether this can feasibly be loaded with bullets as long as the 105gr A-Max and what barrel twist is necessary. |

Also, I would like to know whether this can feasibly be loaded with bullets as long as the 105gr A-Max and what barrel twist is necessary. No, the 105gr A-Max is not a good fit for the 6x45. It is at its best with bullets from 65gr to 90gr. I'll see if I have any load data for it. I guy I know had one of these in the mid-late 90's. |

Could not find what I was looking for, so here is some data from Handloader Magazine.
6x45 Custom AR-15 Load Data |

6x45 shines with bullets in the 80-85 grain weight...........no slower twist than 1x10........longer and heavier bullets are better suited in the .243 Winchester............Barnes XBT and Nosler partition in 85 grain.......are excellent for deer sized game.................80 grain Sierra Blitz....is a decent varmint bullet..............

Do you by chance know the gas port size on the 16" carbine length system? |

RedFalconBill, are those all loaded to mag length? How much velocity would be lost with a 20" or 16" (if you know)?
6mmAR, if I'm reading your post the only bullet listed at mag length is the 75gr, can the others be loaded to mag length? What length barrel is that info with? Thanks for the help guys. |

What length barrel is that info with? Thanks for the help guys. All the load were loaded to COAL of 2.260". Expect 30fps to 80fps less with a 20" barrel. The 6x45 seems to like barrels between 18" to 22". H-335, BL-C(2), and TAC are good powders to start with. ETA: Looks like the new 8208 xbr powder would be good for this round too. |

Load data came from......Hodgdon Powder over, the years I have have use BLC-2 and Winchester 748..........primarily......I use the 80 grain blitz...by Sierra for most of my shooting chores.........In the past decade I have had three AR uppers and one Remington 700 chambered in the veneralbe 6X45.......
when seating my bullets.......I seat them down just enough so they will fit the AR magazine.......with that in mind I used the same loaded ammo in my 700 remington............ I have only used 20 inch barrels when using this caliber............I was shooting through a Crony years ago and was getting in the 2700 FPS range with the Remington........using 80 grain sierrra and 27.5 grains of BLC-2.........if my memory serves me right............... |

Black hills is making factory ammo, but I reload piles of this load I have 4 that are the best performers.

PRI 5.56 mags will allow you to load the cartridge longer, as well...

Came in handy, the Redding dies I just bought won't seat Nosler BT's down to 2.265". Redding is sending me a different seater plug. |

Admittedly, I haven't tinkered with the two different seating depths to see the difference so I most certainly could be wrong. What does it allow you to do? I assume it allows a bit more case capacity but it doesn't seem like enough to make a big difference. How much does it improve the performance of the round? |

Many/most 5.56/223 mags won't hold a round that's 2.30". Its not a matter of adding performance, its a matter of feeding it. Seating it deeper only decreases the case capacity. |

What it could help with is being able to decrease the jump from the ogive of the bullet to the rifling when using more of a VLD designed bullet types. |

My question is how much extra capacity, and resulting performance, can you gain from .035"? .035 / case body length of 1.438 = .024 or 2.4% more room. And a powder load that say averages 25gr would allow for 25 * .024 = 0.6 gr more powder. |

My question is how much extra capacity, and resulting performance, can you gain from .035"? The placement of the ogive on some 6mm bullets will be inside the case mouth with a mag length of 2.260". Mags like the CProducts Stainless and PRI let you seat the bullet out that extra .030" to .035" so these bullets can be used in the 6X45mm. I think the extra case capacity of .6 grains does not mean to much in this cartridge but every little bit helps with slower burning powders. Joe |

Thats quite a diference .086 - .110 No problem & I hope all is well. Sounds like we will have to wait a little longer. I plan to do some fireforming with my 6mmTCU next weekend.

and keep the COL to maxium AR mag length. BTW, I purchased a steel HK 5.56mm AR Magazine (Wow, what a quality magazine)...I cound not believe that it can hold a amazing 2.302" COL for .223/5.56mm round. Just wish I had some more cash to buy more |

Yes, it is a difference. I got the .110" number from another person that has a 20" bbl. I drilled my bbl before getting the email from Les Baer informing me the 16" was 0.085". I was concerned it might be over gassed and thought I might have to put an adjustable gas block on it. Tried it out first wa regular block and it functioned fine. No extractor marks even using the "O" ring over the extractor spring. Next bbl I'm going to start down at .085 and go from there. I might put an adjustable block on just to see how far down I can go. |

My question is how much extra capacity, and resulting performance, can you gain from .035"? In a 6x45 you'll probably gain 30-50 FPS with a 16" barrel due to increased capacity. I know the extra .04" gives a great advantage to the 6.8 SPC. I get an extra 25-30 fps with the 5.56/.223 loads using PRI mags, which doesn't seem like much, but it definitely helps when shooting at 400+ yards... |

Very similar to the 6.8 SPC (except that I can get 30+ grs of powder in that case)... |

Keep in mind the les baer port is for a 1" tappered extra heavey barrel. If you want to run consistentent in a .750 gas block on a medium or standard barrel 20" wiil function @.093 in a 20" gun and .089 in an 18" gun. We are running .092 in a 10.5" auto works good in the Florida we will se how it works in colder weather. Les made the pressure barrels and Dave Kiff from Pacific Tool makes a match grade reamer.

Has anyone done a 6x45 in a shorter barrel, say 14.5" or even 11.5"
Was thinking that would make for a nice little hard hitting carbine. The thing that interests me so much about this cartridge is it is so easy to make the conversion. All I need is a barrel and a set of dies. |

Maybe I am a little confused I noticed the term 6x45 and 6mm TCU being discussed as if they are the same cartridge. Is this so? Anyway I am jumping into this calibe as well as soon as I get my barrel. In the mean time I am looking at the rest of the stuff needed. What dies are everyone using or recommended? I noticed that most are reloading around 80-85g bullets, how about the 100g? I have a lot of the sierra 100g gamekings for my 243 and was thinking about keeping the different types of bullets to a minimum. Good idea or bad?
