    Ammo testing vs. temperature

    I am wanting to test several different brands, types and lot#'s of 22LR ammo in both my 10/22 semi and bolt 541-T. The goal is improvement for next year's PRS type competition. Problem is, it's much colder now (40-60degreesF) and will only be getting even colder through the winter. The PRS competition season will include much warmer temperatures.

    Am I wasting my time and money trying to identify the best ammo types and even lot#'s (different lot#'s made a huge difference last season with both SK Match and Eley Match ammo) in non-typical temperatures? I am NOT looking to develop ballistic dope, just ID ammo with optimum/improved precision so I can buy a season's worth at the start, and not have to switch ammo mid-season. Benchrest level precision is not required.

    Any insight appreciated.

    Match grade ammo generally does not do nearly as well much below 50deg. Very few, good shooters test in very cold temps.
