Anyone know how accurate these are out to say 50-75 yards?

Also is the #11 ignition reliable in this gun? Will it go off every time.
Or is there a conversion kit available to make it a 209 ignition?

Any help would be appreciated. I am thinking about buying one of these for Whitetail deer hunting in Wisconsin.
I found where I can get one with a stainless barrel .45 caliber. I think it is like 14" long barrel. For around $280.00 brand new.
