As mentioned by several posters above, large rifle primers are taller than large pistol primers by .008". They will fire OK when loaded in pistol brass and may not be a "standing tall" problem when squished down to be flush or below the case head. I started reloading pre-web so I tried a lot of "odd" stuff to see for myself and large rifle primers in large pistol cases was one. I only had problems with one revolver when the primer wasn't pushed back after firing enough to clear the recoil shield...

I have very few variations from what's "supposed to be" and "what I can get away with" when reloading. I look at guns as precision machines that contain up to 50,000 psi just inches from my face and I normally treat them as such. I measure my guns. I practice well known safe reloading practices and even when I "experiment" I have some knowledge of possible outcome. So, even when supplies are short, I see no reason to use component combinations not recommended by common sense, those not seen in my manuals, or just plain stupid...
