Started makin precision paper carts.Measuring my balls,using a electronic powder scale measuring exactly 23.4 grains.Will load using my Rydon loader so the compression on all will be the same.If your not familiar with this perticular loader it does all at the same time, kinda cool.Want to see if the accuracy and velocity stay together.Will be using My homemade powder and balls.Load will be .450 ball and 23.4 grains of powder.I'll have to set compression after I load first cylinder.Will keep posted after I try it.It's to wet to get to my shootin spot today.There's just so much variance in using a powder measure.We'll see.
