The Winchester Model 70 is a legendary bolt-action rifle, renowned for its accuracy, durability, and overall quality. The "Post-64" designation refers to rifles manufactured after 1964, when Winchester made significant design changes to the original pre-64 Model 70. This guide will delve into the specifics of the Post-64 Model 70, exploring its features, variations, and enduring legacy. Understanding the nuances of the Post-64 Model 70 is crucial for collectors and shooters alike.
Understanding the Post-64 Model 70 Changes
Winchester's decision to alter the Model 70 in 1964 was met with mixed reactions. While aiming to improve production efficiency and reduce costs, some changes compromised the rifle's original design. Key differences between the Pre-64 and Post-64 versions include:
-
Control Feed: The pre-64 models used a controlled round feed (CRF) system, ensuring smooth feeding even with unusually shaped cartridges. The post-64 models initially switched to a push-feed system, which sometimes caused feeding issues. Later iterations of the Post-64 would bring back a controlled round feed system.
-
Receiver Design: The receiver was redesigned for easier and cheaper manufacturing. This resulted in a slightly altered shape and a change from the solid bottom receiver of the Pre-64 to one with a hinged floorplate. Some enthusiasts believe this affected the rifle’s inherent rigidity and accuracy.
-
Bolt Design: While still strong, some details of the bolt were altered. These weren't necessarily negative changes, but some subtle differences exist between pre and post-64 bolts.
The Evolution of the Post-64 Model 70
Winchester's Post-64 Model 70 wasn't a static design. Over the years, several iterations and variations emerged, each with its own unique features and characteristics:
-
Early Post-64 (1964-1980s): These are generally the most controversial among collectors, often criticized for the push-feed mechanism and perceived compromises in quality.
-
Controlled Round Feed Reintroduction: Winchester eventually recognized the shortcomings of the push-feed system and reintroduced a controlled round feed in later models. This marked a significant improvement for many shooters.
-
Modern Post-64 (1990s-Present): The modern Winchester Model 70, especially those produced by FN Herstal after Winchester's acquisition, represent a return to many of the original design features, coupled with modern materials and manufacturing techniques.
Identifying Your Post-64 Model 70
Accurately identifying the specific year and features of your Post-64 Model 70 is important for collectors and for ensuring proper maintenance. Key identifying marks include:
-
Serial Number: The serial number, often located on the receiver, provides clues about the year of manufacture. Winchester's serial number records are valuable resources.
-
Receiver Markings: Look for markings on the receiver that indicate the caliber, model, and manufacturing details.
-
Stock and Wood Features: Differences in the wood type, finish, and checkering patterns can reveal more about your specific model.
Case Study: A Collector's 1972 Model 70
A collector recently purchased a 1972 Winchester Model 70 in .30-06 caliber. Through careful examination of the serial number and receiver markings, he determined it was an early post-64 model with a push-feed system. While the rifle functioned adequately, the collector noted some minor feeding issues with certain types of ammunition. This highlights the variability even within the Post-64 range.
The Post-64's Lasting Impact
Despite initial controversy, the Post-64 Model 70 remained a popular and successful rifle. It maintained many of the qualities that made the original Model 70 a classic, with continued improvements in manufacturing technology resulting in a robust and reliable firearm. Its legacy continues to this day.
Table: Key Differences Between Pre-64 and Post-64 Model 70
| Feature | Pre-64 Model 70 | Post-64 Model 70 |
|---|---|---|
| Controlled Round Feed | Yes | Initially No, later yes |
| Receiver | Solid bottom | Hinged floorplate |
| Bolt Design | Different, more refined | Modified |
| Overall Quality | Generally considered higher | Variable, improved over time |
