Re: The Italian Screw Machine nears Completion

308Nate asked me about who wrote the G Code (whatever that is). . .
That was before I revealed the lathe was LEGO driven.
Nate, getcher kids a Mindstorms set and get'em started early. This is one of my funnest projects.

Here's the code.

It seems this stuff is designed for elementary school kids. Geeze I fit right in.

Oh, for full effect click on the bottom three pics in the first post. They're videos.

At first glance at the title I thought Berlosconi was at it again! Very much like the results,But don't think a similar work shop is gonna fly with the wife.

Any plans for 30cal.?

Re: The Italian Screw Machine nears Completion

Shorty,

There isn't much need for a new 30 cal bullet as there are plenty of selections available for every use.

My motivation is the lack of 270 cal offerings. Many manufacturers are introducing new bullets on a regular basis. However, they skip from 6.5 to 7mm, right over the 270 cal.

I figure there are plenty of 270 shooters that would like a much higher bc that what is offered in a 160 class bullet. The 160 grain range is about right for the WSM and a bit heavy for the Winchester cartridge. However, the same process can be used for the 130 and 140 grain offerings bringing them both to a much more respectable BC and about 10 more grains of weight.

Plus to me, a higher bc 160 grain offering that will handle the riggers of my 270 AM and it's extreme velocities is the great benefit. Push the 160 w/a .6+ bc @ 3500 to 3600 FPS and see what time is taken off flight time at 1500 yards. Its worth the labor!

Load,
Expanded code...I have no idea of what that is. . . Maybe your son can give me some pointer......Really. I'm going to switch to a "C" type code. I better understand that kind of language. Plus its more flexible.

Shorty,

The much more rough (inconsistent) ones I shot for terminal performance were sporting accurate @ 200 yds, around MOA and terminally spot on.

Some will be in the air in the near future so we'll see about the "in the field" bc.
