Blackhorn 209 powder /volume ?
Blackhorn comes in a 10 oz. container ?
It is to be loaded by volume like other black powder? RIGHT ?
My question is : Does the 10 oz. container of Blackhorn equal the 16 oz. volume of say Goex 2-F.
I mean will i get as many 80 grain loads from the 10 oz. Blackhorn as a can of Goex 2-F ?
Does it have more bulk to it?

Yes, you load it by volume, but also using the proper conversion (.7) provided by Western it can be loaded by weight.
http://www.blackhorn209.com/faqs/ Question 5.
No, 10oz does not equal 16oz.
There are 7,000 grains of powder in 1#. There is 16oz in 1 pound.
7000/16 = 437.5 grains per ounce.
10x 437.5 = 4375 grains per container of BH209.
Shots per container.... 1# vs 10oz
7000/ 80 = 87.5 shots of BP
4375/ 80 = 54.7 shot of BH209
Note: I haven't finished my first cup of coffee yet, so no guarantee on the math

To calculate the number of 80g volume of shot from a bottle of Blackhorn, one needs to use the conversion 0.7
Ten ounces of Blackhorn is 4375 grain, which in turn provides 78 shots of 80 grain volume; each shot weighs 56 grain.
The bottle of blackpowder provides 87.5 shot of 80g volume.
The bottle of blackhorn provides 78 shots of 80g volume.
Another thing one may consider is each shot of 56 (weighed) grain Blackhorn will provide more energy to the bullet than each shot of 80 grain (weighed) black powder. One could actually use less Blackhorn, to get the same bullet energy.

More energy with BH209 is a fact. When I shot 100 gr of FFg from my Accura it was pleasant shooting. Then I tried BH209 using the same charge. And although manageable, there was a very noticeable difference on the back end. I still have about 1/2 a can of BH that I will likely play with again this summer.

That is kinda odd - since BH is a smokeless progressive burning powder the should have been a little less recoil in the same charge. BH does not produce the same peak pressure as a T7 load.
That really depends on the weight of the projectile. The heavier the projectile the more efficient BH becomes.
Up to the 250-260 grain projectile the powder shoots nearly the same velocity as does T7 and Swiss BP
This spread sheet shows some of the numbers. The powder loads were all by volume.

The BP seems to have more of a shove while BH is more like the punch of smokeless powder. Velocity may be the same but recoil is different.

You are correct the recoil is different... Real BP and the normal subs burn faster than BH so they reach peak pressure faster and the felt recoil is faster. BH burning progressively is somewhat slower and lengthens the recoil time..
This chart show the 'pressure curves' of various powders... the faster the powder rises to peak then falls off the quicker the recoil might be felt. I know the colored lines are hard to see for corresponding powders but you can see that BH has the longer curve.
On the chart both T7 loose powders create a pressure slightly greater than 25 K while BH just reaches the 25 K line but it occurs slightly later.
