NO JUDOS FOR BODYS!
Use a 357 case, grind the extractor rim off, and slide a large htm blunt over it.
If you shoot a judo or a regular rubber blunt at them, they will bounc off and you WILL loose birds!
Up until a buddy showed me this, I used field points, they work and work well,
Now I use a wrecking ball and it's devastating. Doesnt tear up meat either, a win win situation.
The hex blunts do work, but it managled the grouse I have shot with it badly!
I'd stay away from snaro's.
If there are no dogs present, cheap bodkins if you can find them would be another option though plan on loosing some arrows stuck in trees
. I prefer to line the bird up with the tree instead of launching an arrow forever through the woods, flu flu or not.
For the 10 of the last 12 years I'd spend MOST of my season just chasing grouse. This is what I've found to work the best for me, your mileage may vary but I doubt it!
