I dont know how many bullet dia's we will be making, lots of testing will be needed just to produce one caliber bullet. The 375cal will be one that will be looked at later on due to the 375-408 wildcat. The problem with solid bullets is weight, for example: Take a 350grn 338cal bullet in jacketed lead core, the same basic size or length bullet will be 60 grains lighter in turned material. The only way to get more weight is making the bullet longer, then you run into problems of seating depths and fitting magazines. A monolithic bullet with the same profiles of its counter part, jacketed bullet, will be lighter, travel faster and have a higher BC. There are some Draw backs to lathe turned bullets, if not designed properly they dont work good in std barrels, Cost of manufacture (making jacketed bullets is very cost effective). No matter how you stack it up, lathe turned bullets will be expensive. They should be looked at as if they are only used for specialty purposes, not plinking.
There is a lot that goes into designing and building bullets, i had some 10,3mm bullets made several years ago to my specs by a small bullet company, they worked very well, cut about half the group size from my 408 rifle, sadly he went out of business.
I'm not looking to go into the bullet business, just have some that guys can test and maybe use if they like. Offer them for my custom rifles
