I have umm numerous Winchester 52’s. They all have one flavor or other they seem to like. A bit better than others. But for consistency across the board no matter which one I’m shooting Eley Tenex seems to be the clear winner from my experiences. Benchrest Gold follows in 2nd. Lapua, SK and RWS target rifle all are very good too. As stated by others. Her rifle may prefer one over the other. Buy some of each. See how it does and go with it, you really can’t go wrong but to get maximum precision with off the shelf target ammo. You’ll have to experiment. My 2cents. Lmk if I can help in any way always glad to have a new BR/Precision shooter in the world!She is shooting a Winchester 52. I am going to get her in some competitions. So that’s the main reason for this post. I’m sure I will end up buying several boxes of different types for comparison. Just trying to get any input for ideas on what to purchase even outside my considerations.
