Safety Considerations and Pressure Management

Reloading demands an unwavering commitment to safety, particularly concerning pressure management. Understanding how Accurate 2700 behaves under various conditions is essential for preventing dangerous over-pressure situations.

Pressure Curves and Over-Pressure Indicators

Accurate 2700 typically exhibits a relatively smooth pressure curve, which can be advantageous for achieving optimal velocities without sudden pressure spikes. However, like all propellants, it is susceptible to pressure excursions if load data is exceeded or components are mismatched. Always monitor for classic over-pressure signs such as flattened primers, ejector marks, stiff bolt lift, and cratered primers. These indicators are your primary safeguard.

Temperature Sensitivity and Stability

A powder’s temperature sensitivity refers to how its burn rate and pressure generation change with ambient temperature. While Accurate 2700 is generally considered a moderately stable powder, it is not entirely insensitive to temperature fluctuations. Significant deviations from the temperature at which a load was developed can lead to noticeable velocity shifts and, potentially, pressure increases in hot conditions. It is prudent to re-verify loads if shooting in vastly different climates.

Prudent Safety Practices with Accurate 2700

• Always start low: Begin with the minimum recommended load and gradually increase in small increments.
• Consult multiple sources: Cross-reference load data from several reputable manuals and the manufacturer’s website.
