Bore wipers

[Kurt]

I have 2- .44-77's and 2- .44-90bn's and they all shoot very good with out any problems getting a good load.
I retired the 2 90's because I been getting eye damage from heave recoiling rifles during high heat from what the eye Doc. thinks. I favor the .44 calibers over the .45. I like the .44-75 Ballard. That uses a ..45-90 case necked down to the .44, it's a 2.5" case and the 2- .44-100 Straight's.
The .44-77 took two Bisons as well as the .44-90bn. The 90 dropped him fast with 1 shot. The 77 I had to make a follow up.
I don't understand why the .44's are not to popular.
