I have shot the 75 grn a year now - accurate little head

Little small for my likings. But RAZOR sharp

I would not hesitate to to shoot em at deer. I have not had a blade fall out (3D targets only) but have heard and can see the issue.

Rocket mechanical blades can fall out or bend just by looking at em - and they kill tons of deer - So I can't see the fixed as any different.
