It is okay, if you mean to ask if there are any safety issues about which you should be concerned. The problem is that the powder column is longer, requiring higher brisance as would be provided by the magnum primer. Of the LR primers, Winchester is about the hottest. You would likely be able to WLR primers and not notice a significant problem. In cold weather (say 0 F or lower) you might have an ignition problem. Great first question. Welcome aboard.
Somewhere around 60 grains I start using magnum primers.. even in things like 3006.
Accidentally loaded them in a 3030 load development… the only bad thing that happens was I used 21 magnum primers and that’s the thing I have least.. redid the loads with standard and they seemed to actually behave a little better(groups)z
