6x45-Nosler Varmageddon/CFE-223

[overwatcher]

Looking for a starting point for my 6x45.
Nosler Varmageddon 55 Grain HP
LC09 Brass-New
Fed Primer
CFE-223 Powder
Have Not loaded anything with CFE yet,not sure where to start.
Also have H335,8208 XBR,and Varget if there is a better way to go.

Thanks in advance guys,Brand new to the 6x45.

Here is a guide that I used when I had mine. I didn't see CFE223 in this much. I used H-335 in mine and it worked great.

On 6x45 my approach is to take 223 data and bump tbe given bullet eright charge up to tbe next eeight for ybe 223. If i load a 55 in a 6x45 i use the 60 graon data for a 223. The expansion ratio of the 6 allows ud to push the same weight at a highet speed and we get to use more propellant to do it. Pressure is speed.

PS: CFE 223 did not exist when that chart was made.

Thanks for the info guys.
I will give that a try.
I am also a big fan of 8208 XBR,Works wonders in the grendel.
You guys try it at all in your 6x45?

I have shot 8208 with good results. Mostly using heavy 87's.

I don't shoot 55grs in 6mm but initially after dozens of combinations I found two type of powders that work well.
AA2230 for light/medium
BLC2, CFE or W748 for heavier bullets, including VLD loads.

I have achieved the 6x45 nirvana with the VLD loads and 95gr and 105gr bullets but I am still working in the 95gr due to some stability issues that I have with the 1:9 barrel.

95's and specially 105s are not really feasible w/o the extreme VLD setup but when you are there boy do they perform. I will develop on this another day.

But initially give a try to the AA and Hodgdon loads. H335 is another one that might want to try but I got better results with
other powders.

Keep it safe.

Got to try these out on some ground squirrels and rock chucks...Deadly!
Primarily using this 6x45 build for small critters..love it.

For 55gr-65gr you can do faster powder.
Try the 65gr VMAX with H.Benchrest. Those you can pump safely and also milder loads have been extremely accurate when loaded a tad over typical COAL. Also Benchrest is pretty consistent even with big thermometer variations.
For the 55gr I think H322 should be a good one too although I have not tried that one. Even AA1680 if you have a shorter barrel 16" or 18" maximum as this is already a very fast powder but if done right, very accurate.
With ball powders and 24"BB I am running 75gr V-max at 3,130 avg. at nominal Nato pressures (62Kpsi) using LC '06 '07 brass and BR primers.
With the BB it barely recoils almost like a 22LR and it is a extremely flat load and will put you at 2.3 mils(7.8MOA) at 500 yards. So it is brutal not just on little critters but also fox and coyote. (Shallow for varmint but broad explosive wound).
Keep in mind some ball powder hot loads you might want to reduce if shooting in the heat.

Here some reference points starting at 223rem pressures...

Just a quick point of reference: The 6x45 is a WILDCAT there are NO NATO specs for this cartidge. The use of 62,000 PSI as a top wil earn you shortened brass life and abuse of the platform.

Hi,
Hodgdon doesn't provide data for the 5.56 neither but many people load for it. They do not even make the powders themselves!
data.hodgdon.com/cartridge_load.asp
One will have better luck with Sierras manual for example.
The 6x45 does very well at 62Kpsi. This corroborates what internal ballistics software says and it is very accurate predicting this very easy and popular load.
Even better than the typical donor round M193 or M855 bulk packs we buy (or used to buy now) at the store to shoot in the 5.56 uppers. All great donors of brass from LC virtually free at the range recycling bin. If you get military based ball powders one gets the most from them running hot as they are designed to perform. Like W748, CFE, etc with the tin/bismuth fouling erasing compound is more effectively activated when running hotter.
I am not worry if I can run free brass 5 times or 7 times.
If one doesn't want to spend the extra in nr.41, 450 or BR primers and save some fuel then the below 60Kpsi loads are great but then through the years I have not seen one single piece of evidence that suggests that a well tuned 6x45 that is run with the NATO parent brass and NATO std pressure will give any significant detriment in the accuracy or service life. Again I am not counting my rounds and high end barrels give 3 to 4K rounds accuracy life with some extra for other purposes. It took me two seasons to shoot one barrel when other calibers I would need two barrels for one season even w/o competition but the same regimen of weekly training.

The disclaimer is good and it always applies, start low, use caution with ANYTHING one reloads.

The spirit of sharing is always there even if it is 9 months away from Christmas. ho ho ho..

We will not allow unsafe data on this forum. To achieve those speeds, You would have to exceed every load published. Have you ever pressure tested any of your loads? How do you know what your pressures are?

LEt me see if I get this right?. You do not allow hot load data in this forum but folks in this forum post even hotter loads in my thread in other forum but that is ok I guess....

www.thehighroad.org/showpost.php?p=8063571&postcount=242

How do you know the pressures? The math says you are well past the 64K psi unlike mine that I have not even give the precise grain/load so people can work it out safely? I am sure GLShooter load is perfectly safe. I think it is also posted here in this forum.

How do I know the pressure? Here some ideas:
A) Start with manufacturer data always.
B) Run them by quickload first.
C) Compare to equivalent loads, cross validate data.
D) Work loads slowly. Pay attention to preparation, spreads and temperatures.
E) No flattened primers.
F) No extrusion marks of any kind. Pictures available upon request.
G) Case dimensions perfectly normal after several firings. Not much stretching neither.

I have been shooting and reloading for 25+ years both for the job and also for hobby.

Mods in this forum always in the defensive position. Don't want people to come here? Let me tell you, you do a great job at that.

Adios Amigos!

You did notice that Accurate Arms lists loads for the 6X45 that are under the 55,000 PSI range? Hodgdon does it in the 50,000 and under CUP range.

My load you pointed out on THR is from the Hodgdon manual that I started using years ago and the bullet is seated out to 2.366. That is one heck of a lot of extra room to play with on the 87 grain pills. Had they been 105's there would be way to much in the case. I also made sure mine was longer than the stated OAL from the current Hodgdon data. The old book never spoke to that. As for your math the numbers are right there on the Hodgdon board. Maybe you need to go work on that math again.

Accurate loads all their 6X45 to 2.260. That is super in that if gives the guy with common magazines a yardstick to go by. Mixing long vs standard loads can get pretty hairy in some cases. AA showing long and short loads for the 223 in various rifle types could get confusing if a fellow didn't set down and ponder what he was looking at. A new reloader on the scene might gloss over the nuances of that issue quite easily.

So basically if you don't agree just move on. Nothing for you to learn or add here.
