I recently built a custom
varmint/target rifle in .22-250 Ackley Improved.
It has a 27-inch barrel with a 1 in 8” twist.
I plan to shoot 80-grain bullets because I want to get
some extended distances out to 1,000 yards.
To get this type of accuracy consistently, it is
important that the rifle be perfectly level.
A canted rifle dramatically affects accuracy.
Refer to the excellent article on the Recreational
Shooting, Inc. website.
So, I needed to find a way to keep my rifle level shot
to shot.
There are many types of
anti-cant devices available; most of which consist of a spirit
level on a mount. Rather
than pay the $30+ for one I decided to make my own.
I found an empty prescription bottle that fit snuggly
onto the scope adjustment knob caps.
I cut the bottle leaving enough room for a wooden plug.
I cut a piece of one-inch dowel 1/2-inch long, then
filed some notches around the edge with a jeweler’s round
file. These
notches provide better grip for the epoxy.
I spread a thin film of epoxy
around the inside top of the bottle, then pushed the notched
dowel into the bottle. I
set the bottle onto the scope cap so the plug was bottomed
onto the top of the cap. I
also spread a thin layer of epoxy on the top of the wood to
act as a filler.
I purchased a cheap sprit level from the hardware store
and removed the vials. After
the epoxy dried, I drilled a 3/8-inch hole in the center of
the plug and epoxied a vial into the hole.
I made sure the vial was level by comparing it to a
receiver level.
 After
the epoxy cured, I painted the assembly flat black.
Now I have a portable anti-cant device that I can
install or remove easily.
