ScrumbagJPL, that's very kind and very helpful sir!
Happy new year to you!

snowmanJPL I'm curious why IMR 4831 wasn't included in the powder selection ? I have a couple 280 Rem and a very similar 7x64 and IMR 4831 is hard to beat accuracy wise and most loading manuals have it near the top velocity wise.

I believe it was:

Hallo Scrummy,
in Austria and Germany they are using a
7x64IX...ist an "Ackley Improved" one using a 30° Shoulder.
left to right: Standard 7x64Case, two 7x64IX with 168grs BergerVLD and 163 Hornady A-Max.
Ballistic out to 1000 Meters.
Best Powder is Norma MRP or ReloadSwiss RS-70

ScrumbagThanks wildcat though I'm probably just going to try and maximise the performance of my existing 7x64.

WILDCAT 762Hi,
N-165 is way to slow.
Try NORMA MRP, Rottweil R-905 or, best Reload Swiss RS-70
Start 56,5grs. giving 863m/sec, MAX. 58,2 is 890m/sec.
