Wow, the size difference is significant.
I think that Bills recommendation for deer and black bear size game under 50 yards is going to be spot on.
These are profiled significantly bigger then standards. I my experience at longer distances hend this size will be more touchy. No doubt they will take more force to push on though game.
One or two might find my way into my quiver elk or moose for the odd spots where i know for a fact the shot is going to be in my lap. Otherwise I am sticking to the standard size.
The blades fit the standard ferrules also FYI.
Here is side buy side with vented 125 regulars vs 125 wides.
