More of a tinkering project , load up some single round to find pressure or run out case capacity then put some on paper. These were rounds 11-16. First 7 were 45-50 grains to see where I would pressure out , done last Sunday. Yesterday 8-10 were shot to warm the barrel.
I now know these will...
A lot of my Wby cartridges don’t have much published load data out there for bullets I shoot. This is where QL is handy , it gets me an idea where to start and work up.
Today got around to shoot some of those in my S2 Vanguard. I’m using American Reloading MP-521 powder , sold as BL-C2 equivalent. This stuff has given me good ES in every cartridge I’ve tried it in. Overall I’m satisfied in the outcome on a small work up.

48grs
Just trying to wrap my head around this. 2 primer , 4 powders and 5 bullets all with the same results. Back when I started with my Muzzeloader I thru charges by volume and never saw that much spread.
Man I’m going to have to pass on it. I’ve stocked up on 8lbers of H4350 , Superformance , Hybrid 100V and N560 to last a long time. By the time I burn thru all of this the price might be more affordable.
What I’m referring to is the bottom.
Every stock for B&C needed to be cleaned up so the bottom metal/trigger guard drops in smoothly. That’s the biggest issue I’ve found with them on the Wby MarkV and Vanguards.
Have you marked these to see if they are carrying over to other loads with poor ES?
Is there a pattern to which shots are slower or are they just random?
The first thing I do with a new B&C stock is chuck up a small drum sander in the drill press and relieve around the action screw so the bottom metal drops in smoothly. I’ve had to do this to every one I bought. A couple I’ve had to shimmed the back action screw to level the bottom metal.
