Part 1

The last time I looked at the Marauder was when I was out of the hospital for 4 days in April. Today, thanks to the help of Mac, I’ll look at velocity. Mac tested several pellets you’re likely to use in the rifle. Because pellets have been coming up with odd weights lately, Mac weighed them to see what they really weigh. He tested Sam Yang, H&N Baracudas, Benjamin domes and Eun Jins.

The H&N Baracudas ranged from 29.8 grains to 30.3 grains. That’s a very tight spread, but not as heavy as advertised (which is 31.02). The average weight for Baracudas was 30.0 grains. We’ve weighed the Benjamin domes before, but Mac did it again. This group ranged from 27.3 to 27.9 grains. An EXTREMELY tight spread. The average was 27.6 grains. Beeman Crow Magnums ranged from 26.2 to 26.4 grains. Again, an extremely tight spread. The average was 26.3 grains. Eun Jins ranged from 35.1 to 36.0 grains. Also, not bad for such a heavyweight pellet. The average was 35.4 grains. Sam Yang was the heaviest pellet of all, ranging from 42.1 to 42.4 grains. That was also the tightest spread. The average weight was 42.3 grains. The longest pellet Mac tested in the Marauder magazine was the Sam Yang, which measured 0.456 inches long. That indicates you can use very beefy pellets in this gun, if you want.

Sam Yang: Velocity ranged from a low of 663 to a high of 676. Average was 671 fps. That equates to an average muzzle energy of 30 ft-lbs.

Eun Jin Domes: Velocity ranged from a low of 712 fps to a high of 732 fps. Average was 724 fps. Which equates to an average muzzle energy of 41.21 ft-lbs.

Benjamin domes: Ranged from a low of 791 fps to a high of 802 fps. The average was 797 fps. The average muzzle energy was 38.94 ft-lbs.

H&N Baracudas: Ranged from a low of 774 fps to a high of 782 fps. The average for this pellet was 779 fps. Average muzzle energy was 40.43 ft-lbs.

The Beeman Crow Magnums: Ranged from a low of 814 fps to a high of 825 fps. The average was 819 fps. Average muzzle energy was 39.18 ft-lbs.

While Mac was testing the gun, all strings were fired starting at 3000 psi. In other words, he topped off the gun between each string. In doing so, he noted that the initial shots were lower in velocity, meaning that this particular rifle needs a fill of somewhat less than 3000 for optimal performance.

Shroud straightened
Mac noticed that the barrel shroud seemed to be pulling to one side when he examined it. Since accuracy testing was next, he decided to straighten it. He loosened the Allen screws that hold the shroud to its bracket, and immediately the shroud centered itself. Perhaps, when it was assembled, it got bumped during assembly. This is something you’ll want to look at when you get your own rifle.

Does your Marauder shroud touch the bracket, as shown above?

If the shroud on your Marauder is touching the bracket on one side, loosen the two Allen screws shown above to center the shroud.

Loosening the Allen screws will send your shroud straight toward the center of the bracket.

That’s it for velocity and power. Next, we’ll look at accuracy.
