Description


The Big Bore Panda and Long Big Bore Panda actions are derivative of the standard Panda action and are designed for those competitors who need to use either a dovetail or side plate mounted ironsight. The Big Bore Panda’s ribs are available in a narrower 60° dovetail or in a Picatinny style rail. The rib also can be parallel to the bore or with a0° 20’ tilt for long range use. The 60° dovetail has been narrowed to accept an Anshütz style iron sight. A side mount has been integrated into the design for a Redfield/Warner style sight as shown above. Since these rifles usually use larger calibers than the standard benchrest rifles, an integrated recoil lug has also been added to increase the recoil area.

Aluminum Bolt Plug Trigger Bracket and Screws • Front, Middle and Rear Allen Head Guard Screws • Spiral Fluted Bolt • Aluminum Trigger Guard • Grease

Chambering Instructions


When chambering for a Panda, Kodiak or Grizzly barrel cut the tenon 1.0625” in diameter by 1.115” for a cone bolt action or 0.980” for a flat bolt action. For an Atlas barrel cut the tenon 1.0625” in diameter by 0.692” for a cone bolt action or 0.557” for a flat bolt action. It is recommended that the first 0.110“ from the rear of the barrel be turned to 0.966” diameter. Leave the rear end of the barrel square for now.

Thread the tenon 1.0625 inches in diameter by 18 threads per inch. If you are using the three-wire method to measure the threads, the measurement should be 1.0715” plus 0.0000“, minus 0.0020” using 0.032” wires.

For zero headspace on a cone bolt run the chambering reamer in until the head-space gauge is flush with the rear of the barrel. For zero headspace on a flat bolt run the chambering reamer in until the measurement from the base of the head-space gauge to the shoulder of the barrel is 1.115” for Panda, Kodiak and Grizzly actions or 0.692“ for Atlas actions.

For a cone bolt set the compound feed of the lathe to 30 degrees. Touch the tool to be used for cutting the cone at the chamber edge and lock the zeroed saddle stop against the saddle. Now back off the stop 0.135”. Using the compound feed only, cut the cone. This should give approximately 0.007” – 0.010” of space between the bolt and the barrel. On a 338 Lapua Mag. barrel the cone will cut away some of the length if a smaller diameter section is turned at the rear. This will leave the tenon closer to 1.089” in length with a 0.966” diameter rear section.

For actions with a removeable recoil lug add the thickness of the recoil lug to the tenon and headspace length. For example: an Atlas flat bolt action with a 0.250” recoil lug would have a 0.557“ + 0.250” = 0.807” tenon length and a 0.692“ + 0.250” = 0.942” headspace length.
