If the wall only had a shallow bullet pit, Gloda would definitely not have noticed it.
After all, the concrete wall was meant to stop those stray bullets.
But the crater he saw was about as wide as a fist, and as he moved closer, he noticed that it was over twenty centimeters deep, narrowing further inside, forming a funnel-shaped deep hole.
Considering it was rigid cement, a five-centimeter deep bullet pit was already quite impressive.
The power of the FN rifle wasn't that great; he had tested it himself. Even at a fifty-meter range, it couldn't penetrate to a depth of ten centimeters.
So he was puzzled about why this bullet pit existed.
Had someone secretly tried a sniper rifle here?
That was absolutely impossible!
The sniper rifle range wasn't here, and the staff definitely wouldn't allow someone to bring a sniper rifle into this range for testing.
Moreover, a sniper rifle wouldn't create a bullet pit of just this width.
Could it be a Colt style of powerful handgun?
