Since thecommercial introduction and immediate success of in-line ignitions in 1985,we’ve seen a flood of muzzleloader action designs introduced to deliverstraight-into-the-breech fire. Oddly, and in a curious reverse evolution, thefirst actions were complicated modifications of a pull-to-cock mechanism. Thosegave way to simpler bolt actions, and bolts yielded to even simplerexposed-hammer, break-open actions.

Now Remington hasgone a step forward–or you might say backward–by introducing the simplestin-line design to date. The Genesis firing system has only two moving parts,yet it solves all of the complications and drawbacks inherent to in-linemuzzleloaders.


As with manymuzzleloaders, in the Genesis an exposed hammer strikes a floating firing pin.On impact, the pin drives forward to strike a cap, in this case a 209 shotgunprimer. What’s unique to the Genesis is that the firing-pin assembly is housedin a solid steel block that pivots out of the way with the flick of a finger.Once pivoted, the breechplug is exposed for capping, decapping or removal forthorough cleaning.

Flipping-breechdesigns were experimented with when cased cartridges were introduced. Thatapplication was limited to mild-pressure cartridges because of the rearwardmovement from the case during firing. With a muzzleloader, there’s no rearwardmovement or pressure except for some slight gas blow back through the touchhole, making a flipping breech ideal.

RigidConstruction: This design approach gives the Genesis rigidity in thebarrel-to-frame lock-up that break-open designs can’t match. A steel underlug,milled as part of the barrel, fits into a matching cutout in the frame, and thetwo pieces are secured with two screws, essentially creating a stiff, singleunit. That translates to long-term accuracy and repeatability, with none of theloosening tolerances found with break-open actions.

While in-lineaction styles have been diverse, there is one constant in every .50-caliberoffering. All are supplied with a 1:28 twist. That configuration is optimal forconical or saboted hunting bullets. The Genesis is no exception. A charge of100 to 120 grains of black powder or Pyrodex and a bullet weighing 295 to 325grains delivers the best results.

Stellar Accuracy:For testing, I cleaned the barrel and fired a fouler before firing eachthree-shot group. With the 300-grain Winchester Supreme Partition, the325-grain Buffalo SSB and the 295-grain Power Belt conical, the Genesis neverexceeded 2½ inches at 100 yards, with some groups in the 1- to 1½-inchrange.

Solid Design:Remington plans to offer the Genesis in the entire gamut of stainless andblued, plain and fluted versions, with numerous stock choices. Prices will varyfrom $284 to $599, based on hardware and stock. I have no doubt that the leastexpensive will shoot every bit as well as the highest priced. This is a solidbasic gun, and the external options are purely cosmetic.
