Yeah, I set YTC (Yakima Training Center) on fire once... The whole thing. ONE Raufoss round --we told 'em it was gonna happen. Sagebrush in July. Spent those two weeks "training" to fight brush fires instead. Whole brigade did.
I have a shit ton of API/T for an M2HB and won't use it until it starts raining around here. Not taking any chances. They get out of control FAST.
Using tacer you also learn bullets don't always embed into the berm, rather, they usually take a 90 and go straight up and elsewhere!
Be safe.
