I've almost exclusively stuck to the hodgdon family of powders and love the 322 in my .223 break action but sometimes it's not very available around here so in preparation thought I'd look at the accurate, Lyman says 23.2 starting load 25 Max on a 50 gr, accurate says 23 is the max! Obviously there can be differences batch to batch, but I was a little bit surprised that the min would differ so much, obviously I'll start real small and watch for pressure problem, but has anyone ever noticed performance inconsistencies with this powder? - just noticed Sierra lists 21.8 for min and 25 for Max......more of a curiosity at the difference from book to book and batch to batch that made me smile a bit.

Remember to pay attention to what bullet type, the seating depth and all the other variables there are when comparing different recipes from different sources. This may account for some of it. But yeh I get what you are saying it made me a little nervous about which one to follow too. Find the one that matches what you have the closest.
 
Haha, loads found online via downloadable PDF are even that much different from accurate's printed load data in my "loadbooks" (love these loadbooks BTW everyone, just recently stumbled across them and they're awesome, no-one around here ever heard of them before, but one caliber one book is just amazing!) I just hadn't noticed such fluctuations from hodgdon loads so found it curious and will proceed with caution, if I could have I would have grabbed some 2230 but alas sold out, I'm definitely gonna start buying more 8lbs every chance I get, powder and primers are more scarce than rooster teeth around here!
 
A man with two watches never knows what time it is. So much data out there these days. I would trust Sierra as well since you have that data. How does it match up to the PDF?
 
The PDF is showing 23 Max, Sierra shows 21.8 to start but maxes out 25 I'll play around this weekend and see what I get, I was hoping 23 would be mid range at most cuz velocities shown on less are dissapointing, but I also don't like Max pressures either, generally I'm .5 under Max at most with good results and longer case life generally speaking. Either way, I won't complain too much about having to test these out ;)

.223/5.56: 23.5 Grs 2015 and a Hornady 52 Gr Match (2249) bullet gave me an Average 3008 FPS from an 18 inch barrel at 67 degrees.
 
Exactly, looking for 3000 or better and that's quite helpful as well, I'm not loading for an ar but Sierra was nice enough to break down their data for both ar15 and bolt rifles, for an ar they show up to 25.2 xmr2015 @3100 fps on a 20" bbl 52 gr hpbt and the loaddata for my h322 is identical to the 2015 with this pill, slight differences in the 50 gr pills but only by .2..... part of what drew me to the 2015 aside from availability was the similarities to h322 that I'm familiar with, I'll share my results Sat but my Christmas to me chronograph ain't here yet, so all info will be related to pressure signs and groupings, I'm using that fragile lil 50 spsx out of a 12 twist 20" and I don't anticipate many problems it was just surprising that Accurate themselves would have such differing data, the printed data I have is not new, but neither is the powder....I'll start with their 2016PDF version and work up to my printed loads, might even find I like it better than the 322 but I'm still itching to play with the 2230 as well as some reloder, I'll be stopping at a local store soon and buying out as many 8kegs as I can afford before folks figure out they're there lol, the cfe223 looks intriguing but more powder per load... gets slightly less cost effective.
 
Also, 2015 on paper performs great with larger pills so it might get used for a friend's 65 Sierra deer load.
 
Most powders shoot best (lowest standard deviation of velocity, and usually best groups) at the point just shy of the maximum load.

You said "break-top," so I'll assume this is a Handi-Rifle. Twist-rate of the Handi in that caliber varies. Use the cleaning-rod method to check yours if you don't know which it is.

55's will shoot fine in the slow-twist and the fast-twist barrels.
Heavier bullets require the faster option (1:9 twist in later-model Handi's)

We'll assume for now you are shooting 55-grain bullets.

In the meantime, you should consider buying a sufficient quantity of the powder you like best.

Nothing wrong with the 2015. But is that what you really want to stock up on?

My rule of thumb is: Maintain a three-year supply of ammo supplies for the guns you shoot on a regular basis. That way, spot-shortages or panic-buy events won't leave you stuck with the chore of load-development for a component you don't really like.

I'm almost out of the large rifle primers I stocked up on during the Bill Clinton primer scare.

I have enough 5.56 brass to almost surely last me as long as I will continue on this earth.

If you have a large supply of powder, KYBMO.
Quantities of gunpowder and primers are a fire marshall issue.
 
Thank you for the extra input but I did state 12 twist (1:12) this is Cva.. with a 50 gr spsx...... and while the input is great..... I think maybe we got carried away here

It seems that info was posted before fully reading what had already been stated and while there were some very educational points listed in your posts (and I in no way mean to offend anyone here) it seems that when we got into 55fmj and twist rates etc etc, the wealth of information veered past the original content aim of variables in printed load data from source to source for the 2015 powder, and while the information you supplied would be great for other purposes it doesn't clarify much when the information supplied is for "assumed" cartridges not in play I'm using .223 rem not 5.56 NATO so we are discussing different chamber pressures, and assuming 1:9 when 1:12 is supplied is not helpful to the use of an already predetermined 50gr spsx to reach velocity of 3000 as I am not loading a fmj nor 75 gr of any kind. I'm certainly not trying to be offensive but much of the content left me wondering what we were discussing as it pertained (or not) to the musings we started with. In response to whether 2015 was the powder I truly wanted to stock up on or not, I would prefer 322 but as stated availability is limited at best most times thus the start of this whole shebang.
