6x45 Load data

No...not the average of the loads, but an average of starting charges.

Take the average of a couple of powders on either side of yours. Average the starting loads and work up from there.

Ie Take BL(C)-2 and 748, maybe h335 and average all 3 starting loads to get your base.
 
That makes sense. What about pressures of different powders? I'm assuming that's why we're starting at the beginning loads. Thanks again for the help. Of the powders in my range, have you had good success with any of them? Sorry for so many questions, just don't want any catastrophic failures to a VERY expensive build, not to mention personal injury.
 
I pretty much only use IMR-8208 XBR in my 6x45s. It just works for me. Plenty of other folks are using your powders listed

It looks that the buckammo.com site is down? I can't get it to come up.

If you start on the bottoms end, and work up, I don't see any issues.


W-748 25.6
H-335 27.0
BL-C(2) 28.0

I would start right at 26 gr, go up by 1/2 gr increments…WATCH FOR PRESSURE, and report back. Be meticulous a pay attention to what the loads tell you.
 
Sounds good. I've loaded 105 rounds for break in and fire forming using 24 grains of Varget and 72 grain Barnes Varminators. Once I shoot those, I have 3 more loaded with 26 grains of 8208 and the 80 Grain Barnes TTSX, my intended pig load. I got that data from hodgdon's website, so I'm comfortable with it. It's an average load. Those are the ones I'll look VERY carefully at. They were kind of "crunchy" as I seated that long bullet, but they seated fine at 2.275.
 
That's why I want the 2460 to work, besides having a lot of it. I don't think it will be a compressed load for that bullet.
 
All my 6X45 loads are rather crunchy. Just look for the normal pressure signs and go from there. Compressed loads are nothing to worry about. A drop tube may help you get more powder, more cleanly, into the case.

I made this one for my full case loads.

 
Both powders, 2460 and 8208XBR are right up to the shoulder, maybe a little lower, but with that TTSX being 1.08" long, it definitely pushes powder. I'll fire those 3 TTSX's I have and see. I like the drop tube. What bullets are you using with your 8208? The other issue is that I live in lead free California, so I'm limited to bullet choices for hunting rounds, and I like the tipped bullets for reliable feeding. I might just have to try and find some AA2015, 2230, or 2200..........Another question, well, more of a theory, hotter powder for light bullets, slower powder for the heavies?

As a general rule, that is correct. There is a happy medium, finding it is the hard part.
 
That explains why 8208XBR is so well liked for the 80+ers. Even compressed, it's at 44,000 CUP, which is well within pressure ranges for the .223 case.

Thats cute…lol



Just messin' a bit with you...
 
Probably sounded like popcorn popping! Yeah...that Varget fills the cases. One of my pet loads in .223 was 27 grains of Varget with the Hornady 50 grain GMX. Looks like I'm not going to worry too much about 26 grains of 8028XBR. Might have to go buy a few more pounds of the stuff. After crunching, no pun intended, the numbers on those burn rates, it looks like 24.3 grains of 2460 is a starting load.
 
I am using some IMR 4320 for my 6X45 which is about identical to Varget as far as burn rate but the powder grains are a tad smaller and fit into the case a little better than Varget. I still get a little crunch but not as much as the Varget.

Right now the 3 powders I'm going to do some testing with for 55-95 grain bullets in my 20" 1-9 twist BHW barrel is H335, H4895, and IMR4320 and I hope to have some results soon......if this arctic cold would ever decide to leave!

Funny that Accurate tells me that the AA2460 is too slow for the 6x45, but it's marginally slower than their own 2230. Makes me curious!!
 
I sent an email to Accurate about loads for the 6x4, here is their response:

NOTES:
It’ important to note that SAFETY is our prime concern therefore we strongly recommend.
1. TO ALWAYS BEGIN LOADING AT THE RECOMMENDED MINIMUM “START” LOAD and develop loads in 2% increments towards the MAXIMUM load.
2. If at all possible, measure the velocity and correlate with our data.
