What are common loading errors for .360 Buckhammer cartridges?

Question

Accepted Answer

Incorrect Powder Charge Weight When loading .360 Buckhammer cartridges, it’s essential to use the correct powder charge weight to ensure proper burn rates and pressure levels. Overloading can result in excessive pressure, potentially causing case head separation, and underloading can lead to poor bullet expansion and accuracy issues. A common mistake is using the same powder charge weight for all bullet weights, which can be problematic due to varying case capacities and burn rates. For example, using a 45-grain charge for a 180-grain bullet may not be suitable for a 220-grain bullet, as it may result in underloading. Consult the manufacturer’s recommendations for specific powder charge weights for each bullet weight.
Insufficient Case Preparation Another common loading error is insufficient case preparation, particularly in the neck area. Failure to properly clean and deburr the case neck can result in inconsistent seating depth and bullet expansion, leading to reduced accuracy and potential damage to the cartridge. It’s essential to use a proper case neck reamer and deburring tool to ensure a smooth, consistent surface for the bullet to seat against. A minimum of 0.001 inch of case neck clearance is recommended to prevent over-expansion and potential case head separation.
Inadequate Bullet Seating Inadequate bullet seating is also a common loading error for .360 Buckhammer cartridges. Failure to seat the bullet to the correct depth can result in inconsistent expansion and accuracy issues. A common mistake is seating the bullet too deeply, which can cause excessive pressure and potential case head separation. Use a bullet seater die and a caliper to ensure accurate seating depth and prevent over-expansion. A minimum of 0.015 inch of case neck clearance is recommended for optimal performance.
