Really the only way to know is shoot some of each. Most individual rifles are ammo specific when it come to accuracy and consistency. Find a brand you rifle agrees with and stick with it.
My 2 cents
"It is the soldier, not the reporter who has given us the freedom of the press. It is the soldier, not the poet, who has given us the freedom of speech. It is the soldier, not the campus organizer, who gives us the freedom to demonstrate. It is the soldier who salutes the flag, who serves beneath the flag, and whose coffin is draped by the flag, who allows the protester to burn the flag."
