I drove by the US location of the Eley Ammo Test Range in Winters TX. There they have 2 shooting ranges, basically long tubes so that no wind is present. There are Olympic shooters who use this range to test their barrels among other various competitive shooters. Eley has a few of these only in the world. The only 2 in North America are Canada and this one in Texas The business is called Killough Shooting Sports https://www.killoughshootingsports.com/ I was able to buy some Eley ammo there and can’t wait to try it out.
