Finally this morning took the time to do some testing on the chronograph of my Marauder FT. Have shot a few hundred pellets down range and had a successful hunt in the field during the short time that I've owned it. But, never until today have I tested the numbers it's generating.
I only tested two different pellets. One being JSB Match Exact Jumbo 15.89gr. The other JSB Jumbo Heavy 18.13gr. The 15.89's that I tested, as well as Air Arms Diabolos 16gr, are the ones that I have found myself shooting the most. I haven't tested the AA 16gr yet. I imagine that they will probably test very similar to the JSB 15.89's.
JSB Match Exact Jumbo 15.89gr. Shot 8 strings of 10 shots per string.
String #1 String#2 String#3 String#4 String#5 String#6 String#7 String#8
High 808 812 809 812 816 813 806 782
LO 780 792 799 801 801 803 787 720
AV 800 804 805 805 808 807 797 753
ES 28 20 10 11 15 10 7 62
SD 8 6 2 3 5 3 5 8
JSB Jumbo Heavy 18.13gr. Sot 4 strings of 10 shots per string
String#1 String#2 String#3 Spring#4
High 764 765 764 768
LO 759 758 759 760
AV 760 762 762 763
ES 5 7 5 8
SD 1 2 1 2
The results were not really very surprising to me. What they show is that the regulated Marauder FT produces a fairly high shot count with moderate but consistent power. With the 15.89gr it averages about 805 fps over 60 plus shots. It was into the 7th magazine that the power level began to fall off a bit. That is good to know. I have consistent power levels until I get well into that 7th mag. This means 60 plus shots before any drop off begins. Not bad, especially in a hunting application. This also makes it a 22.9 FPE rifle with the 15.89gr pellets. Good enough. The heavier 18.13gr JSB's were more consistent for sure and produced about 23.2 FPE. Not enough increase in energy IMO to sacrifice the flatter trajectory of the 15.89gr pellet. Both pellets are very accurate in the Marauder though. The rifle may yet improve some more after a few hundred more pellets down range...I don't know, we'll see. Anyway.....although not the king of power, it gets it done very well and with superb accuracy. I'm enjoying the heck out of it
