I got a cheap KYL target off of Temu, was less than $60.
I’ve shot the 4 largest targets on it with my .30 (75ft/lbs at the muzzle) and they’ve all held up fine.
The 4 smallest have all been shot with my Notos, which makes like 19ft/lbs maybe. All of the smallest have held up fine so far.
I’ve only had it for a few days so I don’t have a super thorough review of it, but for $60 I’d be fine using it the way I have so far (high power for bigger targets, low power for smaller).
However, MidwayUSA has a Birchwood Casey KYL on sale for $99. That one’s rated at 400ft/lbs. The Temu one has no power rating, it just claims to be ar500.
