499HE improvements.
Taking advice from Jack and dozen others, and checking
on availability of cases, making changes.

My 499 HE will now be based on 450 #2 brass as the
supply 475#2 brass it was made from before isn't there.,
And doesn't look as if it will be in good supply or get
run done at any mfg here in states that is convenient and
a good price, for a long time. Back in the 90s when
I first did the case I couldn't find 450 #2 that I wanted,
so I got 475 #2. Now it is opposite only better
as they made a big run o 450 #2, when I was told
they was to do 475 #2.

So 450 #2 Cases are in good supply at
Jamison for less than 4 bucks each.
And I had thought all along that it was 475 #2
that they had. I'm slipping I guess.

The only case difference will be the base reduced
from .577" to .565", All other dimensions the same.
It will still have good taper for extraction in
doubles, singles and falling blocks.


And I'm getting reamer reground to new base size.
And that reamer will be available in 2-3 weeks for
guys to use free. Got a few lined up for this
winter and the change will help. Ed

Jamison has 3-4000 450 #2 cases, which seems
to be 50 times the number of available
475 #2s in the country.This will make
so much easier getting guns setup and
shooting.Ed
