    I have been using Wolf ammo for decades: It has been 100% reliable and has very good accuracy in my firearms. I am very happy with this product, especially on sale, and I am able to shoot more frequently and with more rounds fired per range time. This is very advantageous to keep ones skills honed. Hopefully, the importation of this ammo will continue at these favorable prices.

  • JayG said:

    I've been using Tula in my XDM .45 for plinking and have had no issues so I thought I'd give these a try, but the Tula .223 Rem 55gr malfunctions VERY often in my modern sporting rifle. Every 2-4 rounds caused a failure to eject/cycle, or double feed. I've had NO issues with brass in the same rifle. Not worth the pennies saved, I won't be buying Tula .223 again or even finishing the rounds I bought.
