Not yet... I just picked up a magnetospeed and have been too busy to try out my loads. It does shoot to the identical spot as the Factory Weatherby (the 115 grain Nosler Ballistic Tips). If I'm shooting to factory Weatherby loads, I'm happy. I'm not sure if JJ-65 was serious but I don't think these are weak loads. In fact they are max in most (and over max in some) of my reloading manuals (5 different companies)... Check out the Nosler link... http://www.nosler.com/nosler-load-data/257-weatherby-magnum/

I've been running 75grs of IMR 7828 with 100gr bullets in my 257 Weatherby's for 30 odd years now. No point in having a hot rod if your not going run it hard. Most loading manuals list lawyer approved data at best or just mild load data for cartridges that they have no test barrel for. The 264 Win Mag is another example of soft data pulled out of thin air and put into print for the masses.
Most Weatherby data is loaded hot to 54000cup from any manual I've seen. Reformed brass is loaded a grain or two lighter compared to Weatherby brass but 75 grains does seem stiff. Not likely unsafe but hard on brass unnecessarily though I would guess. Not sure what you would be gaining at 4000 vs 3800 but not my call.

Don't most guys with a hot rod just toodle around town and meet at A&W to ogle each others goodies?
Don't know what goes on in your neck of the woods but when others see my custom built hot rod .257 in action they insist on buying it on the spot. Lost a couple of them that way before Weatherby started clambering 257s in the Vanguard line for average Joe's.
