Is there any commercial ammo in 6x45? I don't mind reloading, but I don't want to be forced to reload. I've always thought this was an intriguing cartridge.

87’s at 2450-2500 FPS. Really think of all the mag length options and imagine them in a short barrel compared to a 223... ??

I think a 10.5 with a gov front site would be awesome. I just like the long rifle feel and the recoil is a joke in a rifle gas system but this does look awesome and I have ran in my other set up Berger 87 and the are deadly accurate

Built one with an 18" custom barrel. It's a laser beam. The beauty of this cartridge is that compared to 5.56, the same weight bullet is a good 200 fps faster in 6mm. That may sound strange, but it's the physics of more bullet base exposed to the powder column.
For example my 5.56 load with a Hornady 75g match BTHP averages about 2650 fps with a 20" barrel. My 6X45 with a Hornady 75g V-Max averages about 2840 fps with an 18" barrel. The V-Max isn't as efficient as the match bullet, but I use my 6X45 for hunting. With quality 6mm match bullets, I'd expect even a little more velocity over the 5.56. I have a bunch of 85g bullets I'll be loading next. On reloading 6X45, it's no different than loading 5.56/.223. No extra case prep is required. The die sizes the case from 5.56 to 6.0mm, and this is not a harsh strain on the brass. Brass life is excellent and loading this cartridge is no challenge. If you don't reload, then it's probably not worth the pursuit, but I load everything from 5.56, 300BO, .243, 6.5CM, and .308. Reloading is fun and rewarding. |

 Older picture, Yes the NT4 has enough clearance and sounds incredible on it. ?? The barrel is a bartlien we cut at the shop, accuracy is incredible. Still have the reamer. As he said above, it can really move the heavier ones more effectively than a 556. Max loads with most powders often are more than the case can hold, it’s crazy I’m pushing the 87’s 2500 and I’m nowhere near max... . I found old data for faster powders and I have a load with 1680 and lighter rounds that even I can’t believe how fast it is. Love the round. Might do a 20 in one day. Dream plan when I made mine was a Robinson XDR micro in 6x45. The KAC 6x35 pdf has some surprisingly ballistics so why not make it a little bigger since I can’t get a PDW? |

I have a McGowen 18in heavy barrel
Thing is lethal. Mounted on a spikes punisher lower and Anderson upper with a cheap cabelas AR scope and it can do more than my other 5.56 now I am thinking a gov A4 with 6x45 barrel would be sick! Has anyone tried the 70tnts they are cheap and work great |

The 6x45 is one of my favorite wildcats. So I am extremely happy to see so many people using it in here. One of my favorite loads is a seirra 95gr AND using a max load of IMR 8208 XBR. Generally is just too long for most AR15 mags, but could probably work in those extended variants.
I really want to make a bolt action in the caliber. Unfortunately with brownells becoming the sole distributor of the Howa actions, it has been hard to find a 223 short action, mini only and I definitely don't want one of those. May try a savage axis if I can find something cheap enough. I just want a bolt gun to be able to run the long max loads! |

I was going to do that too bolt action wise. But after trying it out and single loading my bill 18 inch McGowen barrel the thing is completely lethal. I have had great work with the 87 he Berger’s I have not tried anything bigger though! The bullet deletion for this caliber is wonderful and honestly better that the 224 caliber. I have no idea why this has not caught on. I just need to submit my order for my custom barrel and be done maybe I will order both an SBR and a gov 20 inch just to see.

On your comment about why it hasn't caught on, I think it's just because 5.56 is so deeply entrenched because of the military. However, if someone had had hit upon the two cartridges at the same time...5.56 X 45 and 6 X 45...I don't think they would have given 5.56 a second glance. Basically a free 200 fps and/or the ability to run heavier bullets at the same fps as 5.56 bullets is a win-win that would not have been overlooked. It's just the way things develop sometimes. As far as reloading goes, there's just no downside...no special brass, no special brass prep, no excessive brass wear, no special magazine, great bullet selection, etc. Once something gets so entrenched for so long in military use, it's nearly impossible to derail it. Look how they keep talking about replacing the M16/M4 platform and even the caliber. If they knew and had started with a 6 X 45 to begin with, it would be the same for that caliber now. |

Reloading is so simple and case life is so good too! I think I have finally made my decision and will go with a gov 20 inch and see how that works it will be an A4 everything minus the 5.56 should be killer I will go with a McGowen barrel too since I love the heavy barrel I already got

Would love to get a AR barrel spun up for it. I just know if I did i would always want to run the long loads and would hate to single load them. But if i come to my senses soon and decide to make an upper, who makes barrel for the caliber at the moment? I know i should be looking at the 6mm ARC as i am set up for the 6.5 Grendel(my favorite normal AR cartridge) so it would be a simple neck down if i didn't want to buy dedicated brass. But 5.56 NATO brass is cheap and everywhere and is still my favorite wildcat.

I got the barrel about 3 or 4 years ago. It's a mystery as to it's origins as it appears to be an original A1 that was re-bored.  Accuracy is really good. close to MOA (if I do my part) with 87 gr Hornady Varmints and 23.5 grains of H335. Was getting decent accuracy with 70gr TNT's and 26.2 grains also |

It best performs with 80-85 grain bullets, that said there are a lot of better 6mm Ar15 rounds on the market to use in that platform. It def has a niche.....Ive like had 3 ar's barreled in it and two bolt guns.........Shooting through a chrony with loads on the high side I was getting around 2750 fps with 85 grain bullets out of a remington 700. Its a very accurate round, easy to reload and gets you in the hunting game in States that dont allow 556. |

No, it is literally just a 5.56 NATO/223 necked up to 6mm. It is just a barrel swap like 300 blackout. No need for special mags or anything. I found out they are still making the 783. So I am probably going to use that as a base when I decide to build one. Debating either a 22 or 24 inch barrel. |

I have an 18" AR and a 16" TC Contender chambered in 6x45, they are a riot to shoot. I make my brass on the Dillon 1050 with the 6x45 sizing die in the very last station, Once fired LC brass goes in (deprime, swage, 223 size/trim, then the final 6x45 sizing), tumble to get the lube off then load. When I'm done firing them I usually turn them into 300 Blackout brass, its just easier to make new 6x45 brass then run them back through. I load 85 grain SP bullets and are plenty accurate. I have a spare R700 SA complete receiver sitting here and am planning to get a barrel made for it.
