I've been working on this idea for a while with my partner-in-crime Sean Pero.... We wanted a heavier bullet that would fit into the .30 cal MRod magazines supplied by Lloyd at AirGunLab which we have designed our new repeating breech around for the Disco Double featured in this thread.... http://www.canadianairguns.com/showt...l-Disco-Double

I've been playing with boattail designs for a while, looking at their subsonic BCs, which are significantly better than a flat based bullet.... Anyway, here is what I came up with for the .300 cal barrels that Sean is supplying.... It's a 70 gr. in solid form, and would be about 65 gr. as a hollowpoint.... and has a Stability Factor of 1.5 at 900 fps in our 26" twist barrel (increasing below that).... The subsonic BC is supposed to come in at 0.16....



While I was at it, I did another design, slightly heavier, for the commonly available .308 cal barrels.... It's 79 gr. as a solid, and about 73 gr. as a hollowpoint, and will have lots of stability in any barrel 20" twist or faster.... It will just fit into a .30 cal MRod magazine.... The subsonic BC should be 0.19....



I have been in contact with Tom at Accurate Bullet Molds, who make custom molds that are CNC bored in either aluminum, brass, or iron, and in 1 through 5 cavities.... You can use any of the bullet designs in his online catalogue at.... http://accuratemolds.com/catalog.php .... You can even order a mold with different cavities, which is my plan, I will be getting an aluminum mold with one of each of the above bullet in it.... I have submitted the drawings to him, and I'll let you know when they are in the catalogue.... I'm really looking forward to testing these new designs....
