When ammo for the Mini-14 is in question, I recommend the cheapest rounds you can get, like the PMC Bronze 55-Grain Full Metal Jacket. Despite the low price, it performs well as a practice round. However, if you want to shoot with better accuracy, you should try the Hornady 55-Grain V-MAX. Additionally, the Federal American Eagle 55-Grain FMJ BT is a bit higher priced, but it’s a good round for competition shooting. The Winchester 64-Grain Power-Point Plus is also worthy of consideration because it’s a go-to bullet for hunters who are waiting for hog and deer season. I suggest you stick to the 55-grain range, and you’ll be just fine.
