As a reloader you know the importance of having the same charge in all of your bullet - you know the difference that a 1/2 grain by weight can make. In smokeless it is much more significant that BP of any of the subs...

Throwing BP charges by grains does not mean that is what they will weigh. I have relaoded for years and I know what you are thinking - same thing each time and how-in-the-heck do you get the same thing every time throwing the powder - you do not, but BP or thesubs are not as explosive as smokeless (creates less pressure) so a small difference in the charge will notmake a big of difference down range as it does with smokeless.

I did weigh charges for awhile and put them in pill cannisters for shooting. But after all these years I have gone back to just throwing the chargetapping 4 times cut the load off and dropit in the gun. The difference down range@ 100 with a 50 caliber gun just wasn't that significant. The other thing I found as I changed cans of powder the weight changed a little bit from lot to lot so i would have do the calculations all over again.

I also use t7 and have the variations between my loads to be veryinsignificant. Shooting through the chrono can verify this. I think how clean/dirty your bore is, the small differences in the thickness of the sabot and even the bullet have a greater effect on velocity than does the powder.... HOWEVER, if money was on the line for cutting a piece of paper in the right spot you can bet your sweet bippy I would measure each load, each sabot and each bullet - and if I could figue out away to measure the power of each 209 I would do that also.. Face it, hunting in different temperatures, different elevations, different winds - plus the variations of loading - a lot of things can effect the point of impact. I rationalize this by saying a 2" group at a 100 is what i need from this semi-primative inline, but I am always trying to get it tighter.

The biggest factor I can share is have confidence in your rifle - shoot it shoot it a lot in all the conditions...

All that said I am probably preaching to the priest - your experiance with center fire has already probably taught you all of this.

Good luck and remember:
