The .338 Lapua Magnum Panda Action
Prices shown are starting prices. Additional Options will add to cost.
The Panda action was the first of the aluminum actions designed by Ralph W. Stolle and to this day is still the most popular action built by Kelbly’s Inc.
Most suited for the Light Varmint and Sporter classes in benchrest, it is also an excellent choice for a Heavy Varmint class rifle, for a barrel-clamped Unlimited rifle, and for a single shot live varmint rifle.
The Panda is available in either standard length or .850 inches longer with an integral recoil lug. Optional with the Panda is a micro port in right bolt/left full size or Shorty main port, left bolt/right full size or Shorty main port, right bolt/right Shorty main port or left bolt/left Shorty main port configurations. The Panda with a Shorty main port has a shorter bolt travel for faster shooting.

Aluminum Bolt Shroud • Trigger Bracket and Screws • Rear Allen Head Guard Screw • Spiral Fluted Bolt • Grease

.338 LM Panda Dimensions
Barrel Tenon Dimensions
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.
