700NE Project - Custom Build Complete Story - Shooting Video - Long Story

Hello All,

I'm sure you've seen the recent post about building my Bernardelli 600NE Sidelock Double rifle.

Well, it was almost 2 years ago that I had Aaron Little build me a 700NE.

Here is the complete story from the beginning.

October 2015

As you may have seen, I was pleading on various forums for anyone to help me obtain some 700 NE brass.

I needed about 30 pieces of the brass for a custom 700 NE double rifle that I'm having built.

I had ordered some Lathe-turned 700 NE cases and was promised an 8 - 10 week delivery - that was 20 weeks ago.

And now I've been told those cases would be another 10 weeks, "at best".

The only extruded cases made are from Bertram, and they cost about $40 each from several sources.

I have these on back-order from 2 distributors, with no idea of delivery. One said it could be over a year.

Even at these high prices, I could not find even a single 700 NE Bertram case for sale - "anywhere in the World".

January 2016

Finally after 3 months a fellow forum member, hubel458, came to my rescue with a suggestion and some 50 BMG brass to be modified into 700NE cases.

Here's how it went. Perhaps this will help others in need.

Fortunately, the 700 NE case is ever-so-slightly smaller at the head, than the 50 BMG case



I purchased 32 pieces of 50 BMG brass for the transformation.



1st, the 50 BMG case is trimmed to 700 NE length.



2nd, the mouth of the 50 BMG is annealed and opened up to 700 NE size.



3rd, the head of the 50 BMG case is turned down by 0.024" to .780" dia.



4th, the heads of the 50 BMG cases are threaded to 5/8-24 for about 5/16"
