Consistency Reloading Tips for Precision Long-Range Shooting

If you don’t have a chronograph to measure velocity (you should if you’re reloading!), then you can find the flat spot on paper. Put a target 300 yards or more (100 yards isn’t enough range to show variance) down range and shoot groups with different charges. The powder weights that result in the smallest vertical groups show your flat spot. If you want to deep dive on this topic, look up Optimal Charge Weight (OCW) or Ladder Testing on the interwebs.

Powder Charge Consistency

Once you’ve found the ideal charge weight range, you’ll want to make sure each and every charge is the same. Ask for birthday gift certificates to Brownells to get yourself something like an RCBS Chargemaster so you can easily weigh every charge. If you measure charges using a kitchen utensil, you’ll never achieve consistent velocity and precision.

Case Weight and Headstamp

Since the pressure and resulting velocity result from the output of a burn in a …Read the Rest
