Finding reliable load data for your 7mm is crucial for safe and accurate shooting. While "Shooting Times" magazine is a respected source, this post delves into Westerner load data specifically for the 7mm, exploring various bullet weights, powder types, and primers, as well as crucial safety considerations and where to find additional information beyond a single magazine source.
Understanding Westerner Load Data
Westerner is a brand known for its quality ammunition components, but finding their specific published load data requires careful searching. Published load data often appears in reloading manuals, specific to the bullet manufacturer (like Nosler, Hornady, or Sierra) and sometimes in magazines like Shooting Times. However, relying solely on one source is risky. Load data can vary based on several factors:
- Rifle Manufacturer and Model: The twist rate of your rifle's barrel significantly impacts bullet stability and optimal powder charges.
- Bullet Type and Weight: Heavier bullets often require larger powder charges than lighter ones. The bullet's design (boat-tail, flat-base, etc.) also plays a role.
- Powder Type: Different powders burn at varying rates, affecting pressure and velocity. A powder suitable for one bullet weight might be unsafe for another.
- Primer Type: While less impactful than other factors, primer type can slightly influence pressure.
Therefore, while a reference to Westerner load data in Shooting Times might provide a starting point, treat it cautiously and always cross-reference with other reputable sources.
Locating Reliable 7mm Load Data:
Several resources offer reliable 7mm load data beyond a single magazine article:
- Bullet Manufacturer's Websites: Companies like Hornady, Nosler, Sierra, and Berger publish extensive load data specifically for their bullets. This is your best starting point. Their data usually specifies the bullet, powder, primer, and case type used, giving a solid baseline.
- Powder Manufacturer's Websites: Powder companies, such as Hodgdon, Alliant, and IMR, also publish comprehensive load data, often sorted by caliber. Their data provides insights into which powders perform best with various bullet weights.
- Reloading Manuals: Comprehensive reloading manuals (e.g., Lyman, Lee, Hornady) contain extensive load data for a wide range of cartridges, including various 7mm calibers. These manuals are a significant investment but offer a valuable resource for years to come.
Safety First: Always Start Low and Work Up
Never assume a load is safe simply because you read it somewhere. Always start with the minimum charge listed in multiple reliable sources, and work your way up incrementally, carefully observing pressure signs. Excessive pressure can lead to catastrophic rifle damage and serious injury.
Signs of Excessive Pressure:
- Flat Primers: A flattened primer indicates excessive pressure.
- Bulging Cases: Cases swelling or bulging near the base are warning signs.
- Excessive Noise and/or Recoil: A significantly louder report or stronger recoil than expected can be indicators.
- Unusual Smoke or Flash: Excessive smoke or flash from the muzzle is another bad sign.
Beyond Westerner: Exploring 7mm Options
The 7mm family offers a diverse range of cartridges. Knowing the specific 7mm caliber (e.g., 7mm Rem Mag, 7mm-08, 7x57 Mauser) is crucial for finding appropriate load data. Each cartridge has unique characteristics requiring tailored load data.
Conclusion:
While references to Westerner load data in Shooting Times can serve as a starting point, comprehensive research from multiple trusted sources is essential before attempting to reload 7mm ammunition. Prioritize safety and always adhere to best practices to ensure a safe and enjoyable shooting experience. Remember to consult multiple reputable sources and always start low and work up. Safety should be your top priority.
