I am loading Remington 22-250 brass with Hodgdon Varget, Hornady 50 grain V-Max being shot from a Sako 85 punching paper at 100 yds. I inadvertently order Winchester large “mag” primers. I read where people have had good results using the mag primer because it is igniting 35+ grains of powder. Has anyone worked up loads using this mix and what are the thoughts of using a “mag” primer for the 22-250?

A magnum primer is utterly unnecessary with less than ~65gr of stick powder, probably more...especially with short cartridges.
With upwards of 50gr or so of ball powder, sometimes a magnum primer can crispen up ignition, again, particularly with longer cartridges.
In your case, with a short cartridge with stick powder, the magnum primer is unneeded.
Will it work? Probably. Just start a little lower with charge weight than you otherwise would of. Assume the mag primer = 3/4gr more powder and youll be safe.

Re: Thoughts on using a "mag" primer in the 22-250
I own two 22-250 Ackleys and usually like at least 55 grain bullets, but one uses 65gr bullets and the other 64gr. My particular theory is that the Improved version allows the use of heavier bullets at higher velocities than can be obtained in the standard 22-250Remington. I like H414, about 44 grains.
But, your question is can I use magnum primers. Yes you can, but more than likely you will be disappointed in the results. The mag primer will cause the slow burning powder to burn a little faster, which defeats the purpose. There are a number of suitable powders you can use in a 22-250 but you will not attain book velocities with any of them because of the unsuitable primer. At least, I doubt it? If you were hunting in subzero weather with a compressed load of IMR4831, well maybe that would be an application. At least some people see an advantage, but as the previous writer said; you don't need a mag primer (large rifle) until loading a 300WM, and even then, I use a standard Win large rifle primer with 80 grains of propellent.
So, you have a misapplication and if economy is important, you can use those primers but none of the loads in the manuals will work, so you need to be very careful
Personally, I'd ask around and see if you could maybe trade somebody for (what I use) Fed 210M primers, or just offer to sell them at a discount to somebody that has a suitable application.
Good luck, BB

Thanks all for the replies. This is what was in the back of my mind but wanted to make sure. Next time I will pay more attention to my ordering..............
