Anyone tried 300MP in either or both of these? 165-170 gr bullets in 350. 250 gr in the 450.

I've tried it in the .350 Legend with 170s, and 27.5 grains worked very well.

25.5 grains also worked with 200-grain Hornady FTXs, which were sized down using a Lee die.

John, I seem to remember you mentioning you had been working with the .350 Legend with an article in the works. Have I missed its publication or is it yet to be revealed? I always enjoy your take on new calibers.
