LRH Members,
Looking for some general numbers. I happened upon a Winchester Model 70 shadow chambered in 300 WSM at a pawn shop. The action seemed somewhat long to me so I went and grabbed a caliper off the shelf and made an attempt to measure the magazine length... I think it is a shade over 3". This got me thinking about a custom throated 7mm WSM... Does anyone have load data for a 7mm WSM with a COAL of about 3.0-3.050, possibly even 3.1" (I am going to try to go re-measure tomorrow with a Hornady chamber gauge)? Looking for powder charge and MV. Would only be interested in the project if I could push 175 ELDX's or 180 Bergers at around 3100 FPS (safely) with a 24-25" tube.
P.S. Was I daydreaming or are the Winchester M70 Shadow WSMs a bit longer than your standard SA?
P.S.+ I am a hunter, not a benchrest shooter, is the 7mm-300WSM really worth chasing over the standard 7mm WSM?
Thanks in Advance LRH Members,
Colton
