Performance & Functionality

The core function of the Mec Mayville 9000G Progressive Shotshell Reloader For 12 Gauge 45308 is to produce reliable, consistent shotshells at a high rate. In this regard, it largely succeeds, provided it is set up correctly. The press excels at handling the entire loading sequence, from powder dispensing to wad seating and final crimping, in a single pass of the handle. This progressive design means that each station is occupied by a shell at some point during the cycle, maximizing efficiency.

Its strengths lie in its speed and the consistency it can achieve once properly dialed in. For those who understand the nuances of shotshell reloading – powder measurements, wad selection, and crimp settings – this press delivers. The primary weakness, as noted by some users and experienced during my initial setup, is the learning curve and the requirement for meticulous calibration. It’s not a system you can just pick up and use perfectly out of the box without prior knowledge or careful reading of the instructions.

Considering its price point and intended use, the performance is impressive. It undeniably meets the expectation of high-volume, consistent reloading for the avid shooter or small-scale custom loader. However, it falls short of being “effortless” for a novice; it demands engagement and a willingness to learn and adjust.

Design & Ergonomics

The design of the Mec Mayville 9000G Progressive Shotshell Reloader For 12 Gauge 45308 is classic MEC – utilitarian and built for function. The cast iron construction is heavy, which is a significant advantage for stability but means it’s not easily moved once mounted. The overall feel is one of robust engineering; there’s very little plastic in critical areas, which inspires confidence in its longevity.

Ergonomically, the large operating handle is comfortable enough for extended use, though its arc requires a decent amount of bench space. The stations are well-laid out, and the automatic systems reduce the need for excessive manual manipulation, which is a boon for comfort over long reloading sessions. The primer feeder is a practical addition that improves the overall user experience.

A minor ergonomic quibble is the necessity of careful positioning during setup and operation to avoid interfering with the automatic indexing. It requires a certain rhythm and awareness of the machine’s cycles. The markings on the press are functional rather than decorative, clearly indicating the purpose of each station.

Durability & Maintenance

The durability of this reloader is, in a word, excellent. The cast iron frame and well-machined steel components are built to last for decades, assuming reasonable care. I’ve seen older MEC presses still in regular use after 30+ years, and this model feels like it’s cut from the same durable cloth.

Maintenance is relatively straightforward. Keeping the machine clean from powder residue and shot is essential. A light application of oil or grease to the moving parts, particularly the ram and indexing components, at regular intervals will ensure smooth operation. The MEC design philosophy generally lends itself to easy maintenance, with parts accessible for cleaning and lubrication.

Potential failure points, based on user feedback and general mechanical understanding, often revolve around the alignment of components or wear on smaller parts over extremely high volumes. However, for the average user, the core components are exceptionally robust. The plastic parts, if present and of concern, are typically not load-bearing and are designed for specific feeder mechanisms rather than the structural integrity of the press itself.

Accessories and Customization Options

The Mec Mayville 9000G Progressive Shotshell Reloader For 12 Gauge 45308 comes with the integrated E-Z Prime primer feeder, which is a significant “accessory” that enhances its functionality out of the box.
