Nothing I can add beyond Mr Sagebrush. Note he has had standard velocity wadcutters for sale as well. Personally, that is what I would suggest for folks with limited practice in a lightweight revolver. Winter or summer. I loaded some hard cast poly coated 148 gr for my wife and daughter. Have not chronoed them but with 5.5 gr PowerPistol they are very comfortable in an Airweight S&W and a Model 15. If you have components and still wish to provide practice ammo just load wadcutters up with Bullseye or comparable powder at standard velocity.
Your generosity is noteworthy. God bless and keep you.
And I noticed MacKay has a website though it is under maintenance.
