View Full Version : NOE molds ballistic coefficient?

Does anyone know if NOE gives out approximate exterior ballistics, ballistic coefficients for their molds or is this something I have to get two chronos out and do the math to get?

I'm looking for the BC for this bullet so I can plug it in to get approximate ranges for the various points on a ballistic reticle given a known muzzle velocity and work out exacts from there.

It is usually at the bottom of the drawing showing all the variables. Like lube capacity. And the BC.

That seems to be the only drawing I can find of this bullet on their site. Am I not looking in the right place? They have several molds that feature this bullet design and all seem to have the same image.

His old software didn't give that info. You should Email him and ask if he has converted that design to the new software. If he has, that will give you your info.

Thank you! That makes sense as to why some bullet drawings have it and some don't. I'll contact him and see.

W/ the dimensions you can figure it out w/ this calculator: http://tmtpages.com/calcbc/calcbc.htm

Looks like approx: 0.296 according to that calculator.

Read the notations at the bottom of the page about BC equals Sectional Density, this should get yo real close;

Strangely; I had a similar question about the same this week. Swede responded to my PM question in a short period of time. Synopsis is that on NOE's forum they have the NOE Boolit Drawings with higher quality diagram resolution than appears on their Web Site for procuring Boolit Molds. Most of them have the estimated Ballistic Coefficient on these drawings.

Go to the below link and find the appropriate Boolit Drawing:

Thanks for that. The drawings in the store are marginal quality for my mold spreadsheet. The higher res images will help a lot.

Thanks but that link doesn't show the 460 350Gr RF anywhere

That section is still under construction. Some of the molds I have had the dimensional drawings while others didn't.
