Chris,

I believe I made that mold somewhere around 2008 or 2009 and I have altered it in someway a few times since then. The last thing I did was in 2017 when I shortened it from the original length of 1.460" to 1.435". Since then it has shot like nothing else I've ever work with, it is amazingly accurate. So over time the exact dimensions have been kind of "muddied" a bit.

I just measure one because I really couldn't have answered your question if I hadn't, I flat out didn't know. So the OAL is 1.435" the shank is .685" long which leave the nose at .750". The answer then is 52%. I did not realize the nose was so long! No matter, it shoots great.
