"best ammo" would be based on your opinion of it and if your gun likes it. Everyone will tell you what they prefer, but its best for you to figure what works better for you.
Example: me and a buddy went to a range one day with exact same ammo Winchester White box .45acp 230g FMJ. Both of us were shooting Kimber 1911s. His model was a Pro Carry, mine a Combat Carry.
I had a bunch of FTE/FTF. His ran flawless.
almost Every gun is picky about what it likes to eat.
