Whidden Gunworks Frequently Asked Questions
Question: Should I use a Whidden Bushing Die or a Standard Whidden Die?
Answer: Both the Whidden Bushing Die and Whidden Standard Die are manufactured to tolerances that exceed most expectations. The Whidden Bushing Die allows the flexibility of neck tension should a different thickness in the neck of the brass occur from one manufacturer to another. The bushings also allow the shooter the opportunity to achieve the desired neck tension after neck turning of the brass. The bushings allow for .001” increments in neck tension in a range from .17 to .338 calibers.
The tolerances of the Whidden Standard Die give a repetitive measurement time after time. The Standard die comes complete with a die locking ring to allow the operator to secure the die at the preferred setting. Once the die is set, the locking ring is simply secured using an allen head machine set screw. This allows for a consistent setting from one loading to the next without need for adjustment.
NOTE: Whidden Gunworks is not responsible for any misuse of the Whidden Die Systems. Any damage that occurs during the normal operation of the die/dies that does not follow the manufactures directions will not be considered for warranty.
NOTE: Whidden Bushing Dies are not intended to be used without a bushing. (AND YES...... it’s happened)
Question: What are the possibilities of having a die made to my specifications?
Answer: Whidden Gunworks strives to allow the shooter to have most flexibility in the shooting industry when it comes to reloading dies and reloading components. Virtually any die or die set can be manufactured through either one of two ways. The first is by sending a schematic print of the reamer of the chamber one wishes to have made the die made for. The second way is by mailing three (3) spent rounds from the chamber of the weapon that the dies will be manufactured for. If the later is used, an average of the three spent rounds will be used to cut the die/dies. Once the information is received, a custom die form will be completed and kept on file for future reference.
Question: How long from the time my die order is received until my die order is complete?
Answer: Die orders are processed as soon as they are received. However, Whidden Gunworks only begins die orders once a month. Should an order be received after that months order has been started, the new order will be placed in the next months batch. The dies are sent for heat treating once each month. The dies are returned to Whidden Gunworks when the entire order for the month has been completed. Lead time for Custom dies is currently averaging 14-16 weeks from the the 1st of the following month in which your order was placed and your brass or reamer print was received by us.
Question: What Bushing is correct for my Whidden Bushing Die?
Answer: Measure the neck diameter of a loaded round that you've produced with the brass & bullets you plan to use. Subtract .002 from the diameter you measure to select the correct bushing size.
NOTE: Measuring several loaded rounds and using the average is advisable.
AS AN EXAMPLE: loaded rounds measure on average .270 at the neck.
.270 - .002 = .268
In this case a .268 Bushing would be correct.
Question: How do I install a Bushing in my Bushing Sizer Die?
Remove decapping assembly by unscrewing top plug on sizer and removing the entire assembly. Drop in the bushing (ensure you’re installing per instructions on the card supplied by manufacturer). Re-install the decapping assembly. NOTE: Do not over tighten top assembly plug. Allow the bushing to float as this floating action is key to prevent runout. Check the adjustment of decapping assembly to ensure decapping pin is protruding at proper length. Whidden Gunworks bushing dies will accept Whidden Gunworks, Redding and Wilson bushings.
Question: If the neck of my rifle's chamber is .XXX, May I select the desired bushing for my Whidden Bushing Die from this measurement?
Answer: NO. It is not advised. The bushing size is dependent on case neck thickness and bullet thickness, not the chamber of the rifle.
Question: What is the neck diameter of a Whidden Gunworks Standard non-bushing die?
Question: What are the caliber options available for building custom dies?
Answer: Too many to list, we have the capability to manufacture a variety calibers, from modern to obsolete. We currently do not build dies based off .50 BMG family. Standard size dies are 7/8’’ OD Note: Dies 1.25’’ or 1.50’’ incur a $50.00 upcharge due to their larger size. Example: If a .375 CT sizing die alone is ordered the additional charge would be $50.00. If both the sizing die and seater die are ordered the additionalcharge will be $100.00.
Question: When ordering a Custom non-bushing die how can I determine neck size?
Answer: We recommend the following formula
Average bullet diameter + Brass neck thickness (number x 2) - .003 thousandths = ?
Applied to a 6mm Creedmoor
.243 +.014 x 2 (.028) = .271 - .003 = .268 .268 would be the sizing hole diameter
Note: Ensure you measure the brass neck thickness not the neck diameter for this formula.
Question: Should I want a standard caliber die or set of dies, is it required that I wait the same amount of time required as custom die orders before receiving them?
Answer: Whidden Gunworks strives to keep in inventory most common standard die sizes ranging from .22 cal. to .408 cal. The usual ship time for any item in stock is 2 days.
Question: The Decapping Pin keeps falling out of my Decapping Rod. Does this mean that my decapping Rod is broken?
Answer: No. To solve your problem, first remove the Expander Button and Decapping Pin from the die. Next, using pliers, slightly squeeze the "clamping jaws" that hold the pin. Lastly, install the decapping pin and the Expander Button back into the die.
Question: How do I adjust my Whidden Gunworks Full Length Resizing Die so that it is sizing my brass properly?
Answer: With the Whidden Gunworks resizing die it is not necessary for the die to touch the shell holder as in the case with most dies. Begin adjustment by placing the die in the press with the die threads setting fully extended. Next place a piece of your brass in the proper shell holder of the reloader and lower or raise the brass until the loading press is in a fully “cammed-over” position. Begin adjusting the die so that the contact surface of the die makes contact with the brass. Raise the handle of the press and adjust the die using small adjustments each time the brass is inserted into the die. Continue adjusting until the desired sizing is achieved. The die should be just above the base of the brass once the brass is sized properly.
NOTE: These directions apply only to standard Single Stage Presses. Please contact the manufacturer of your press to see if using “cammed over” is appropriate for your particular reloading press.
To ensure that proper sizing is achieved, each set of Whidden Gunworks Dies comes with our Whidden Gunworks Shoulder Bump Gauge. The Shoulder Bump Gauge works in conjunction with your calipers. The Shoulder Bump Gauge attaches to one shoulder of the calipers and allows the neck of the brass to fit internally. The calipers is then closed onto the brass with the shoulder coming to rest against the inside shoulder of the Shoulder Bump Gauge. Once the calipers stops a measurement is taken. This is the amount of shoulder setback that the sizing die is achieving. Adjust the sizing die until the desired measurement is reached. Your Whidden Gunworks Sizing Die is now set.
Question: When bumping back the shoulder of my brass, how do I determine that the shoulder is to the desired measurement to properly fit the chamber of my rifle?
Answer: Whidden Gunworks also offers caliber specific case gauges to determine if the shoulder of the brass is set to the desired measurement. These gauges are cut to exacting tolerances from reamer schematics for each standard caliber.
