Reloading - Accuracy and case capacity filled:
I would like to pose a question on reloading. What effect does the
percentage of case volume used have on a load? If I were to use a powder
that came closer to filling my case would the potential for accuracy increase?

"Usually" a case that has 90% or better will be a more accurate
or consistant load, but not always, a good example is Varget in a 30-06
there is enough air space left over to, as someone said, "Keep a mouse
alive for a week" and it shoots great. I know this probably didn't answer
your question but there are exceptions to every rule.

Daniel; this could touch a contraversy about primers but If you
have any amount of air space that concerns you. Shoota can always do magnum
primers to insure the ignition is a bit better. I shot a road of varget
in a .300 win magnum that would hang fire on regular primers and shot one
hole groups with magnum primers. Ah So! but grasshoppers do not rush into
the temple with roading book and try this to cure every accuracy problem
as it is a rast resort for me to increase ignition fire. Mucha betta to
sorve another way! Many powders just prain work better if they are even
a bit compressed. But when they have to Tamped to get it all in the case
I get orrf there!
Solly if engrish suffa ,just had Chinese food rast night.

As far as reloading with powder not reaching the maximum case capacity
is purely a matter of what the case will hold and the pressures of the
powder used. As stated earlier you can use Varget in the 30-06 case and
have an air pocket, but then there is the other extreme that loading up
cases with a powder drop tube just to be able to fit the recommended powder
in the case according to the various reloading manuals. Then you have to
crunch the powder when seating the bullet. The only exceptions to this
is to try to reach at least 90% cases capacity with the overbore magnums
(i.e. 7mm STW, 257 Wby Mag, 378 Wby Mag, etc.) If you don't, you could
get a hangfire, and SHIT that smarts, particularily with the big boomers.
Magnum primers with these boys are a MUST. But thats a different topic.
Almost started to ramble on, but I caught myself. I'm getting better.
