One Hole Group – Special Interest
Group
Phone: 920-757-6135
|
The purpose of One Hole Group is to discuss, tryout, and compile our
collective knowledge of precision shooting. Primarily for our own
enjoyment and use but also for the upcoming generations so that they do not have to repeat our expensive mistakes on the road to that
ultimate goal of putting 5 shots through the same hole (the "One Hole
Group").
The SIG is open to all TCR&GC members who share our interest in
precision shooting. All aspects of the One Hole Group goal will be
discussed: rifles, handguns, optics and reloading - including the
selection and maintenance of the equipment - also methods of use
thereof.
|
We are in the organization mode at present. If you
are interested in participating, now is time to get involved (if you
don't get in on the ground floor you will have to use the stairs
later). Please
talk to one of us at the range or use the contact Email above.
The usual suspects to contact (often at range and didn't say no fast
enough) are: Al Neveau, Bob Risse, Dan Safranski, Pat Medo, Tom Eby, and Fred
Bohl

Dan Newberry's Optimal Charge Weight Load Development (Used with
Dan's permission)
OCW web page
"What is an Optimal Charge Weight load? — With any given bullet and
powder combination, there will be a specific amount of that powder
which will cause the bullet to exit the muzzle at the "friendliest"
portion of the vibration cycle. This does not necessarily correspond
with the tightest velocity figures, however. Many load recipes have
over the years become the "go to" recipes for trying out a new rifle.
If your rifle fails to shoot one of these "tried and true" recipes
well, you may well have a rifle integrity problem. Consider the
Federal Gold Medal Match .308 win ammo. How can one recipe shoot so
well in so many rifles? That's what we're after in the OCW load--a
load recipe so stable and predictable that it does indeed rise above,
and to some extent disprove the "all rifles are different" adage of
lore..."
