"ajshoots"I finally got around to sizing and testing the heavies out of my 2 custom mrods. One is set at 964fps with standard jsb kings. It shot the heavies at 870fps. The other gun is set at 840fps with 43gr eunjins. That gun shot heavies at 915fps.
Both guns have proven equally accurate and the heavies were nearly the same out of both guns even with the speed difference. I only had a chance to shoot out to 75 yards, but both guns shot them to moa accuracy out to 75. Under these same conditions, I would have a hard time shooting to the same level with standard jsb kings in the same wind conditions. It is apparent that the heavies are very good and with a higher BC, they are definitely better in the breeze!! As a note, these are the original heavies sized to .250". Not sure why they made a change as these fit just fine prior to sizing in multiple marauder mags? Hope the new MKII's are as good as the originals!!
