.266 (6.5) SP /PB 100~120 Gr

Also need to look at how much bullet is sitting inside the case vs outside the case.  It would affect the case volume for powder and such.  I need to go measure one of my grendel cases to see how long the neck is.

What do you think of the drawing listed above?  How would you change that one?

yeah, I was playing with the meplat diameter and bullet length inside the case–if I make it more pointy, then the BC goes down, unless I increase the nose length.  I still need to try to measure the neck length of the grendel to see how far this bullet would be sitting in, but I kind of like this design.  As far as beveling the base, personally I am not sold on bevel base cast bullets, but have not tested them much to have a real opinion to go off of.  I do know that with a regular plain base, it is easier to have a “perfect” squared base when powder coating vs the bevel which can have imperfections due to the powder coat.  For example, like where two bullets might stick together on the beveled area, and when you break them apart it may leave an imperfection in the coating.  I would think that this would make the bullets fly worse than an almost perfectly squared base with a plain base config.  Maybe it’s all in my head–I need to test it out.  But if I were going to shoot this bullet, I would probably want it in the pb config instead of bb.  2 cents?
