  • Francisco from USA asked:

    Anyone know the pellet weights used to determine the published velocities? The publish velocity of 1,000 fps gives 8.884 fpe with a 4 grain alloy pellet, yet with an H&N 21 grain Pile-Driver it gives 46.642 fpe; in other words, does anyone have any chrony values with the weight of pellet used?

    • Tyler from USA:

      If you watch the video review linked on the page, you'll see that 10.3 grain pellets were running around 960 fps. So that 1000 fps mark was definitely achieved with lead.

  • Christopher from USA asked:

    Is there any way of adjusting the piston internal pressure to vary the FPS to suit different needs (Hunting to Target)? This is one thing I really like about my Weihrauch HW90.

    • Aatif from Pakistan asked:

      what is ft/lb energy of this gun....how to calculate this

      • Francisco from USA:

        Greetings Aatif from Pakistan, the way to calculate kinetic energy in foot pounds is you get yourself either paper and pencil, or a 99 cent calculator as I do then you enter your pellet weight in grains then you multiply by the velocity and multiply by the velocity again then you divide by 671 and you divide by 671 again then you push the equal (=) symbol on the calculator, the number on the screen is the energy in foot pounds. I love the Pyramid calculator, but I am not always near a computer.

      • Tyler from USA:

        If you click on description, on the right hand side of the page, under the video thumbnail it will say "unit converter for airgun measurements" Click on that, plug in your pellet weight and velocity and it will calculate the energy

    • Wayne from USA asked:

      How does this rifle compare to the Weihrauch HW90 Rifle in power, accuracy, and overall quality?

      • Tyler from USA:

        The HW90 is the better gun, but the 350 N-Tec is a very close second. They run around the same power level. Accuracy should be great from both, though I tend to give the edge to the Weihrauch. Both are great quality coming out of Germany and you'd be hard pressed to find better guns of this power level.

    • Russ from USA asked:

      I own the RWS/Diana 350 Magnum in .22 cal. Is my gun able to be retrofitted to house the gas piston version shown in the latest Pyramydair video? That video speaks about the .177 cal. but the new version gun is made in .22 cal.

      • Tyler from USA:

        No, the gas ram does not drop into the older spring piston Diana rifles.

    • Tom from USA asked:

      Why doesn't the video show the cocking action? Is it break barrel? wouldn't that be a feature to review?

      • Tyler from USA:

        It's about a 55 lbs, pretty stout but smooth because of the gas piston.

    • aurora from USA asked:

      I was wondering if this same rifle uses both calibres 0177(4,5mm) and 0,22(5,5mm) or just one?

      • Tyler from USA:

        Theoretically, you could swap the barrel/breech block assembly with relative ease if you could purchase extra barrel assemblies.

    • Sean from USA asked:

      What is the fpe. out of .22 & actuall fps. A chrony?

      • Scott from USA:

        Around 840 with JSB 16 grain. Don't know the foe.

    • John from USA asked:

      Will the gas ram unit of this gun fit in the N-TEC 340 (.22 cal)? Seems like it could be a quick power upgrade. If so, how can I order one?

      • alex from Canada:

        Dear John. It won't fit. The action part of this rifle is longer.

    • Greg from USA asked:

      Shouldn't the fps be 1320 like the ar8 I mean they are the same rifle in different stocks

      • alex from Canada:

        Yes Greg. I think you're absolutely right on this.
