Anyone can help me out .. I have 2208 and 2206h powders.

Nope I forgot I use a proper method of using the Forster nut it will give you a proper measurement to the ogive Shank Junction unlike the hornady rubbish and others that mesure way off

So the overall cartridge length is well over three inches long?

I gave in and ordered the Berger manual. It says 22.2 of 2208/varget is the max powder charge. How did you arrive at 24.1gr and any issues?

i am only getting 2450-2500 fps from this powder charge with the bullet seated jammed 10thou into the rifling. there is a lot of empty space in the cartridge when i shake it!!
what max charge (2208) have people safely used?? im tempted to go higher than 22.2 but wanted to know what people have done before i blow myself up

If you are seating the bullet long then you would expect to be down on velocity. Seat the bullet to 2.260" COAL as stated in the load data if you want that sort of velocity. I'm seating my 80's at 2.450" and they are still well short of jammed so you probably need to be closer to 24gn.
A max load is only the point where they started seeing pressure signs during their testing, with their firearm, and their loading techniques. Your max in your firearm could be earlier or later than theirs (if you are increasing the size of the combustion chamber by seating long then your max will be significantly later). To find your own max load you will have to keep increasing the charge until you start to see pressure signs. I prefer AR2206H over AR2208.
COAL is a critical part of the load data as it dictates the pressure - powder type/charge weight/bullet weight/COAL.

I loaded it jammed, them 40 thou off, 80 thou off and 120thou off the rifling as per the berger VLD suggestions. it is seated quite deep at 120thou off as the ogive was almost into the neck at that point. could just measure the CBTO measurement. cant remember exactly what it was. will check the COAL tonight when i get home.
i chrono it at the deepest seating depth and the velocity was around 2500+. so still quite low.
if i understand you correctly, you are suggesting i can exceed the max charge in the book if i seat it longer than their COAL... but i should probably increase the powder charge slowly ...

Going to load 24gr 2208 and see.
Thanks guys
