Quick Answer
Handloading the .35 Whelen can lead to mistakes such as overloading cartridges, using incorrect powder charges, and failing to properly seat primers, which can result in reduced accuracy, increased pressure, and potential firearm damage.
Insufficient Powder Charge Research
When handloading the .35 Whelen, one common mistake is not conducting sufficient research on optimal powder charge weights. This can lead to under-loaded or over-loaded cartridges. To avoid this, consult the Hodgdon Reloading Data Center or other reputable sources for recommended charge weights, such as 67-69 grains of 4350 for a 250-grain bullet at maximum pressure. Keep in mind that different powders and bullet weights will require adjusted charge weights.
Incorrect Primer Seating
Failure to properly seat primers can cause a variety of issues, including inaccurate chamber seating, inconsistent ignition, and potential firearm damage. To avoid this, use a primer seating tool to ensure the primer is seated 0.020 to 0.030 inches deep, which is the recommended depth for most modern rifle cartridges. This will help ensure accurate and consistent ignition.
Overreliance on Loading Manuals
Loading manuals can provide valuable information, but they should not be the sole guide for handloading the .35 Whelen. Each rifle and cartridge combination is unique, and loading manuals may not account for specific factors such as barrel length, action type, and environmental conditions. To achieve optimal results, combine loading manual data with personal testing and experimentation to find the perfect combination for your specific rifle.
