First Impressions of SIG SAUER Marksman Hunter 7mm Remington Magnum 160 Grain Sierra Gameking Brass Cased Centerfire Rifle Ammunition E7RMGK160-20
The SIG SAUER Marksman Hunter 7mm Remington Magnum 160 Grain Sierra Gameking Brass Cased Centerfire Rifle Ammunition E7RMGK160-20 promises a blend of long-range accuracy and reliable performance for medium game hunting. With its boat tail design, skived bullet nose, and Sierra GameKing projectile, this ammunition is designed to appeal to hunters seeking consistent expansion and a flatter trajectory. Having spent over a decade field-testing various ammunition types in diverse hunting scenarios, I was eager to see how this offering from SIG SAUER would stack up against the competition.
My pursuit for the ideal 7mm Rem Mag load stemmed from frustrating experiences with inconsistent expansion on whitetail at varying distances. I needed ammunition that could deliver consistent terminal performance at both close and extended ranges. The SIG SAUER ammunition, with its emphasis on controlled expansion and long-range accuracy, seemed like a potential solution to this issue.
Upon unboxing the SIG SAUER Marksman Hunter ammunition, the first thing I noticed was the clean, consistent brass casing. The boat tail design was visually appealing and suggested the aerodynamic efficiency described in the product details. The overall build quality appeared robust, indicating a focus on precision and reliability.
Compared to other 7mm Rem Mag offerings I’ve used, such as Federal Premium and Remington Core-Lokt, the SIG SAUER ammunition stood out with its emphasis on long-range competition-level accuracy. While the Federal and Remington options are known for their traditional hunting performance, the SIG SAUER ammunition seemed tailored for hunters who prioritize both precision and terminal ballistics. I chose this ammunition over others to test SIG SAUER’s claims of superior long-range performance and consistent expansion.
My first impression was one of cautious optimism. The ammunition looked and felt well-made, instilling confidence. I was excited to get to the range and, eventually, the field, to see if it lived up to its promises of accuracy and consistent terminal performance.
Real-World Testing: Putting SIG SAUER Marksman Hunter 7mm Remington Magnum 160 Grain Sierra Gameking Brass Cased Centerfire Rifle Ammunition E7RMGK160-20 to the Test
First Use Experience
I tested the SIG SAUER Marksman Hunter ammunition at my usual shooting range, a facility that allows for shots out to 500 yards. The conditions were typical for late fall: cool, with a slight crosswind. I used my trusty Remington 700 rifle chambered in 7mm Rem Mag, a rifle I’ve used for countless hunts.
The ammunition performed admirably right out of the gate. There were no failures to feed or eject, and the rounds consistently chambered smoothly. Recoil felt manageable, and the report was consistent, indicating a uniform powder burn.
I encountered no significant issues during the initial shooting session. There were no misfires, hangfires, or any other indications of performance problems. The only surprise was the relatively clean burn, leaving less residue in the action compared to some cheaper ammunition I’ve used in the past.
Extended Use & Reliability
After several months of consistent use, including multiple range sessions and a deer hunting trip, the SIG SAUER Marksman Hunter ammunition has proven to be exceptionally reliable. I’ve fired approximately 100 rounds of this ammunition. I have experienced zero malfunctions.
There have been no signs of wear and tear on the ammunition itself, and the brass casings remain in excellent condition for reloading. Cleaning my rifle after each shooting session is a simple task, with minimal fouling.
In comparison to previous experiences with other brands, the SIG SAUER ammunition outperforms in terms of consistency and accuracy. Previously, I had issues with inconsistent groups and occasional failures to eject with other brands. This SIG SAUER ammunition has eliminated those issues, providing a level of confidence I hadn’t experienced before.
