Remington Model 700 Ultimate Muzzleloader

posted on June 9, 2014

One of the showstoppers at the 143rd NRA Annual Meetings & Exhibits was the Remington Model 700 Ultimate Muzzleloader. The company unveiled its new smokepole in front of a crowd of more than 75,000 attendees, calling the gun's Accelerated Muzzleloader Performance (AMP) ignition system a "jet engine of progress" and claiming it brings "300 yard performance to muzzleloader season."

This isn’t the first time Remington built a muzzleloader on the Model 700 action. In fact, the company was one of the first to bring a bolt-action inline to market with its Model 700 Muzzleloader in 1996. It was discontinued eight years later, probably because the heavily modified 700 action seemed to be more about aesthetics than any real advantage in performance.

In the new Model 700 Ultimate Muzzleloader, Remington uses its short-action 700 receiver and a specialized breechplug to harness the ignition of a magnum rifle primer, which produces a longer, hotter flame than a 209 primer. The system reliably ignites up to four, 50-grain pellets of blackpowder substitute. No mistake: four pellets for a muzzle velocity just shy of 2400 fps with a saboted, .45-caliber bullet weighing 250 grains. That’s about 200 fps faster than a three-pellet load can do with the same bullet. It beats most .45-70 Gov’t loads and is on par with the .444 Marlin.

Rifleman Q&A: U.S. Model Of 1928 Thompson Variants

I was reading an auction catalog, and a reference was made to an American military Thompson submachine gun. It stated it was a “1928 Colt Navy overstamp, not a Savage.” The catalog made that verbiage seem important. What’s the significance of the “overstamp,” and were there other military 1928 Thompsons besides the Navy guns?
