Winchester USA White Box 10mm 180 gr FMJ 20 Rounds Ammunition – USA10MM

This is some of the weakest 10mm ammo available. If you just need something to shoot out of your 10mm, I guess this will work. It is not sufficient for real training ammo as you will be quite unprepared for the recoil of a true 10mm round. Best use is probably to collect the brass and reload it to actual 10mm spec. Overall, it does function/cycle normally, it's a little dirty, as all white box is.

As long as you read the box first and know that you are only getting 466 ft-lbs of muzzle energy you will enjoy shooting these rounds. For the full 10mm experience get some sig elites.

Cycled fairly well in my Kimber Eclipse Custom II, however, this is a very finicky weapon. Fewer failures to feed compared to Federal brands. Good accuracy, but the ammo I reload is still the most accurate that I have used. Excellent brass for reloading. Very good price at Sportsman’s Warehouse (on sale). Until recently I didn’t know that Winchester offered 10 mm Auto in white box. At some point I plan to purchase more.
