7mm Rem Mag
10/21/2014
Current load is for a Rem 700 Long Range, 26" BBL 9.25 twist, B&C M40 stock.
Win brass
CCI250 primers
Berger 168 VLDS .080 off the lands
68.6 grains Retumbo
@2820 fps
Load is pretty mild but I'm getting pressure signs with factory ammo and with reloads around 69.5 grains when I was only jumping .010.

Headspace.
Yet again.
The beauty of a 7mmRemmie on a 700 in OEM guise,is the relationship of throat,twist and COAL latitude.
Form a fale shoulder on the Virgins,kiss and carry on.

180 VLD even with the lands
H-Retumbo 71.2C
This has proven to be "the" load in two near identical rifles, one mine, one a friend's. Light Palma contour 1:8.4" twist, spiral fluted. On virgin brass it made 2935 fps. After firing in my rifle it grew .014" and I bumped the shoulders .002". The next time I out it made 3020 fps. It hits like a train!

Any pressure with this load and what is your elevation? I've got good accuracy at 69.2 grains of Retumbo with the 180 HVLDs and have test loads up to 69.8 but didn't know how far to take it.Rate now:

My elevation is 600' ASL, and I developed this load in August 100F. Maybe the occasional extractor swipe, but that's it. I even tried tweaking it a few months ago, going .3 gr and .6 gr below as well as .3 and .6 gr above. It did not improve. As I said before, two rifles, same length and contour, each shot exactly the same load the absolute best.

Recently had the pleasure of tuning a heavy bench rest gun for a friend . If anyone reading this is interested
in seeing a serious piece of hardware , have a look on you tube for ' March 80 x " .
EDIT : the owner made the vid , was a 300 WM , now has a 7 RM barrel fitted .
Load details ;
Norma brass , oal trimmed to uniform case length
necks lightly skimmed to take off high spots
Federal GMM primers
62.9 to 63.1 grains of a recent lot of H4831 sc ( AR 2213 in Aus )
Berger 180 Hybrids straight out of the box ( would benefit from trimming and pointing )
seated 8 to 15 thou off the lands ( shot better than jammed , or longer jump every time )
Velocity is around 2970 , shot in the 0,1 range at 200 meters ( 220 yards )
Load has been replicated in standard Tikka Varmint , with accuracy in the 0.3 range at 100 off Atlas bipod ,
