    One of three barrels I have for my SPA  P12 is a HW 100 4.5 mm, 605 mm long. I have tested a wide range of 4.5 mm pellets JSB 16 gr Beasts, 16 gr Sam Yang, 21 gr Piledriver and JSB 13 gr Monsters and many more.

    The beast and Piledriver pellets pulled away from the others and the final test was my silicon baffle box.
     
     The Piledrive pellet had zero distortion after been shot into the baffles box, whereas the beasts deformed nicely. On this test results I chose the .177 JSB Beasts as my .177 pellet of choice.
     
     
    I am a bird shooter so I am always looking for a pellet that is accurate and kills quickly (energy transfer). Over the last year or so JSB Beast pellets have not let me down just check out these average target shooting groupings. I am not a great shot, it’s the barrel, pellet and velocity combination that allows these groupings.   
     
     
     

    3 weeks ago I went feral pigeon shooting and invited a new shooting friend to join me, we managed to shoot a bag of 42 birds. I won shot of the day by clocking the only myna at 79 m.
     
     My friend was shooting JSB 18 gr at 880 fps from his Cricket, I couldn’t help myself comparing the killing potential between the .177 16gr and the .22 18gr. The .177 beasts killed pigeons quicker and further, my new shooting friend also noticed.

    This last Friday, after work we visited the silo’s again but this time my friend brought his .22 FX Bobcat which launches JSB 16 gr at 900 fps. We shot 32 pigeons and I lost shot of the day to a great 90 m shot, but .177 beast out killed .22 16 gr, Score 2 / 0 to the beast.  

    In closing, my friend flew to New York this last Saturday Night, he’s a pilot but he is returning with a .25 Cricket. He lands this coming Thursday and I know my phone is going to ring and I am going to be asked, if we can go pigeon shooting this weekend. I will keep you up to date on .177 Beast vs .25 King, that’s assuming he going to shoot King’s or King Heavy’s. If he pulls a tin of .25 Polymags out, I am dead in the water.

    I’ve had some luck with them shooting 25m Bench Rest when there is a lot of wind. Ordinarily the JSB monsters shoot best out of my RAW TM1000, but when the wind is over a certain speed, I think the beasts do better. Indoors, the monsters are more accurate though.

    @chasdicapua
    I also found 800 fps to be a very accurate velocity.

    At what velocity have you been shooting the beast,  for bench rest shooting?

    the fastest I could shoot it and still stay under the 20fpe limit for Heavy Varmint class was about 740. I imagine up around 800 or higher it would be even more accurate, but then one would be in open class.

    The .25 Cricket has landed and I am told it”s shooting hole on hole with King’s at 910 fpe.

    I managed to delay the “Beast vs King” pigeon shoot out until next weekend. I went to the range instead to test my newly required .357 Jkhan N400.

    Only thing I can add to this thread is that I bought 6 tins of them from AGA and they are by far the most consistent batch of pellets I have ever sized with all but 14 being the 4.52 head size that was marked on the tin bottom red sticker and those were 4.51 ,   weight wise they varied from 13.2 to 13.8 gr. which is very good compared to other JSB’s I have checked!  J.L.

    .177 Beasts are 16.2g the 13.4g are monsters and they are mostly very consistent 

    “whitefox545″ weight wise they varied from 13.2 to 13.8 gr. which is very good compared to other JSB’s I have checked!  J.L.

    Yes !!  Sorry!  My mistake, can’t keep the names straight!! but the Monsters are the best Ive seen or checked!  I just don’t understand why if they can make one size accurately they are so bad on others like the 10.34 heavy’s, there TERRIBLE!!  I guess they just don’t care.
