Few minutes anyway.  I picked up a big jug of Blue Dot a while back.  Don't remember if it is 4lb or 5lb.  I have used about half of it.  Plus I went through about 2-3  one lb cans before I started the jug.

Since they're usually out of stock I got two.(all they had) ;D

You will like the BD...single complaint is its a flake powder and dosen't meter like H110/296. But it more than makes up for that in its attainable velocities!

Good luck,

5lb canister and now Jugs...I have gone thru too many 1lb canisters then moved to the 5 pounders, but I wouldn't know about that, just started the new plastic jug!  ;D

Today Win 296 and H-110 are said to be the same...AA#9 seems to a different powder (grains like fine sand) but someone posted that the newer jug was more like flattened ball? ???

A few years ago when A9 was made in Belgium, it was a dark, dull micro-spherical powder. It is now made in USA and is almost as small and somewhat flattened. It is still the tiniest powder kernal I have seen. It is darker in color with a shine under the right light angle. The good news about the recent switch is my early testing appears to indicate that it is less temperature sensative, and it is a little more dense.

When wringing out A9 for all it's worth in 10mm with heavy bullets (180-200gr XTP), is it beneficial to go with a magnum LP primer?

A magnum primer is not needed. The higher bullet pull of the heavier bullets are just what A9 needs to get a good burn. I have used CCI 300s, WLPs (in-between mag and standard), and CCI 350s with A9. I have not found a huge difference with the primers for heavy bullets. However, with lighter bullets, like 155s, where you need to stuff a whole crud ton of A9 in the case; mag primers noticeably speed up the burn rate and increase pressure. Standard primers are better in that situation, in my opinion.

All in all, I would say that one does not need to use mag primers with the heavies. My pet woods load with a WFNGC uses a CCI 350. I did my load workups loosely based upon Speer 200 gr TMJ data. The load works great, and I haven't tried it with a standard primer. For a 200 gr XTP, a WLP primer gives extremely tight high-low spreads on velocities. In the teens or twenties for a 10 shot string. I use CCI 300s for 180 XTPs.

Realistically, I don't see any reason why mag primers are necessary for 10mm for any load.

A bit of "old school" there Shadow!  Cool photo.

Have you noticed any difference between the Hercules Blue Dot and Alliant Blue Dot?

Keep in mind it can also be editions of the same book. Powders do change over time.  A given company will source a new mfg and the burn rates aren't quite the same.  Even different lots have this problem.

There was a time when AA#9 and H110 were the exact same powder.  In the last 60's/early 70's they were both military pulldowns from 30 carbine ammo being re-canistered and sold by different companies.  At that time you could interchange the data, and load manuals had the same data.

Fast forward to today and clearly they aren't the same.  And when you get a jug of surplus WC820 you have to test it carefully to find out if it is old powder (modern AA#9 data) or newer powder (modern H110 data).  But, if you can avoid the hazmat fee it can be a great way to get 8lbs of powder for $100 or less sometimes.

Some of that I had heard, and some was new info to me.  Thanks!

BTW, to anyone;  I've heard tell that AA#9 and Ramshot's Enforcer are practically identical in 10mm.  Can't remember where I heard it from.  Anyone know if that's true, at least for the present time with new powders of each?
Gun Control?  Oh yes, the theory that becoming a victim is somehow morally superior to defending yourself & your family.  Makes perfect sense.

I had not remembered that, so I looked up the Enforcer data.  Ramshot doesn't publish 10mm data for that powder.  The data for Enforcer in 44 Magnum is very, very close the Accurate's data for #9 in 44 mag.  The differences for 200, 240 and 300 grain JPH's were always just a few tenths of a grain.

If you have a good price on some, I would give them a call and ask.  Usually they will comment.  However, looking at online pricing at Powder Valley, it looks like #9 would be a little cheaper.  So unless you have a deal on Enforcer, I don't see a reason to bother.

This is a very dangerious road to travel...

Be safe and assume nothing. THE ONLY IDENTICLE POWDERS CARRY THE SAME NAME AND LOT NUMBERS!!

Even opening a new can of same powder one should drop top loadings at least 10%!!!

Its best to go with There are no "IDENTICLE" powders.

I like Blue Dot but it will NOT meter thru my RCBS powder dispenser. AA9 and AA7 meters very easily.

Good point. This was implied in my post with my recommendation to contact the mfg for data, but not spelled out.

Burn rates between lots, as mentioned, can vary. Over time they can vary a bunch.  H110 is an example.  In the 1970's it was the same as AA#9.  Today, not at all.

I haven't seen enough difference that I can tell without a pressure barrel...still testing more stuff.  Blue Dot begs to be loaded to a fuller case with slight compressed loads for best performance and clean burns.
Working on the upper edge may show a little more differences pressure wise. 
The 200 grain cast bullets I loaded last night I dropped back to 9.8 grains of BD because the bullet is 0.0335" longer than the 200XTP's, so after I test them I know even more with that load.
