My recorded and averaged FPS for the Varget is actually on par with my load data. The load data included a C.U.P. of 44,800 as well. This is load data for a 174grn BTHP/ 180grn SPT mind you and not for a RN projectile.

The rifle used for testing was my French Resistance No4Mk1 Maltby. It is as it was the day it left the factory with nothing modified by way of barrel bedding so, given that, the testing was as it would have been using a factory spec'd rifle with factory spec'd MkVIIz ammunition and then compared with modern-day handloads using very mild load data.
Many, many moons ago, I was told by a very well known LR shooter, knowledgeable with the Lee-Enfield that "Accuracy is best achieved by decreased velocities" and "Speed is your enemy." I have lived by that principle for almost 40 years now and it has yet to fail me. My accuracy load for hunting using either a 150grn SPT or a 180grn SPT is with 36.3grns of IMR3031. It is also my accuracy load using a 174grn BTHP SMK. Load data shows a C.U.P. of 42,400 for all three bullet weights and a mean MV of 2303 with a plus of 8 - 10 FPS for the 174grn HPBT...
