If its the heavier one I tried some a while back. Very limited test not even a packet.
I actually don't remember how it grouped but I do remember it is the only ammo ever to not reliably function in my 10/22. Something like 3 out of a 10 shot mag wouldnt cycle the bolt properly. Probably very acceptable in a bolt, pump or lever action. Think I gave up and put it aside for just that

There is a 42 gr version of the 40 gr which are a bit hard to find at the moment, the Aussie made 40 gr sub is the best ammo i have used for pest control. I used a large amount in 10/22 's and found it functioned very well , it wasn't till about 5000 rounds between cleans that the odd miss feed and non ejection would occur.
