    Yes, my smooth twist barrel will do 3/4-1″ groups @50 yards. That just don’t get it for me. Regular jsb 44g will do hole in hole  @50 yards if I do my part, low wind, and no damaged skirts

    Same here. My Boss stacks them under 50 yrds. Anything above that just be happy with a poi in a “general” kill zone.

    Drid,

    Here are three 5 shots groups of JSB 44.75’s, 50.15’s, and 44.75 Polymags at 50 yards.  My RAW 30 stacks 44.75s at 50 yards (#18) and  50.15s (#16)  I pulled that one to the right on 16.  

    Polymags spray (#17)  into like a 1″ group.  I got them hoping they would be accurate, but they weren’t.  Frankly, I don’t think anything I shoot at is going to need a Polymag vs a  normal 44.75g 30 cal pellet.  The weight is the same as the JSB Exact and head size is only .001 larger on the Polymags so it’s got to be the balance / length of the pellet and the cone that is throwing it around randomly.    The JSB Exacts are .375″ long and the Polymags are .508 long and will not fit in a RAW magazine so measure your magazine for fit.

    if you wanted a handful to try I’ll mail them to you if you cover shipping.  That way you don’t have to buy a full tin to find out if they shoot.

    I’m I’m working with different scopes and didn’t bother to re-zero before shooting these, which is why they are high right in general on the below target.

    Bobbed06,

    Here is what they look like in .177 and .22 from LW match barrels at 30 yards.  6-10 are .177 and 11-15 are .22.  Everything on those rows are 5 shot groups.

    sharroff, which pellet delivers the highest energy, the 44.75s or the 50.15s?

    You can plug the numbers from my above post into this site to get the energy leaving the gun http://www.pyramydair.com/article/What_is_Muzzle_Energy_August_2003/5 There is very slightly more energy in the 50’s leaving the gun. 

    When you say ‘delivers the highest energy’ there are several variables, and you’d need to have something to measure the energy absorbed by the target.  Both pellets will pass though a piece of paper a 20 yards for example and deliver the same tiny amount energy to the paper.  Both would hit a chipmunk at 20 yards and deliver only part of their energy to the chipmunk and have a lot of pellet energy left over after it passes through.  Both would deliver all their energy to a 4×4 board shot at 50 yards.

    They shot really well out of my old P-Rod .22, but they don’t fit in my Daystate Pulsar .25 mag or my FX Impact .30 mag; which is a shame because they deliver the most devastating wound channel I’ve ever seen in an airgun.

    Would any know the ballistics on the jsb 44g and the polymags in 30?

    I just went out with the polymags at 50yds with my Fx Impact and they shot one hole. The funny thing is the jsb 44 & 50g pellets shot the same poi as the polymags at 50.

    Topcat, here are the numbers I got right after I received my new Impact .30 (three months ago) with the JSB 44s [a full bottle; 250 bar to off-reg @ 150 bar (gun manometers); 40 rounds; Chrony Beta Master]:

    Avg. muzzle energy: 76.38 ft#
    Avg. velocity: 876.8 fps
    SD: 5.00 fps
    HI: 884.4 fps
    LO: 862.7 fps
    Spread: 21.7 fps

    Hope this helps!

    Yeah, my P-Rod loved Polymags! It’s a damn shame that my Impact .30 mag will not accept them. Oh well, that’s what I love about airguns; the innovation curve is steeper that that of firearms these days! I’ll just keep an eye out! https://www.youtube.com/watch?v=IQM_kWxrJNI
