Just look through the period of time,the once wildcats became,standard type cartridges. As far as wildcats,my first one was a 22 K Chuck or k hornet as it was called. Next was a 30 Gibbs,219 Zipper Ackley imp,6mmMoto Mag.,17 Ackley Bee,17-223,223Ackley imp. They are fun,and thats the truth.One cartridge i want to build up let i think is a super cartridge and a lot of 600-1000 yd shooters use here is the 6.5mm x 284. Its got some dandy ballistics to it.and makes a super hunting rifle. vangunsmith
