Knocking over targets when you hit them was no problem. Trying to hit a 35mm target at 45 was interesting to say the least. Especially when a bit of wind appeared. up to 30 yards they were spot on. Maybe could be used for 25yd BR? Needles to say I wont be purchasing any in the near future.
It does raise the ? of is 8 yard target too close? If you binned the 8 yarder you would have to compensate for it. 10 yards 15mm or add 2 yards to max range? That could be interesting
