I've updated this post because I've added a pic of calculations I've done that would make a great 147 grain boolit. Taking his MP359-135 and simply removing the lube groove will give a solid land area and by my calculations will give a 147-150 grain boolit. interested?
1) No lube grooves, perfect for Hitek users.
2) 147 grain
3) 6 or even 8 cavity mold
