As expensive as they are they have limitation which I don't like;
#1 they are a pure lead bullet which deform easily once deformed they are worthless as far as accuracy is concerned
# they are outrageously expensive especially considering that anyone with a bit of know how can swedge their own pure lead bullets and can make or have made a die for what ever they want. There are even some available for making pistol bullets that are commercially made .
#3 If you are going to go with pure lead bullets your velocity is limited because you can only push them to about 90 gr of BH and [at least in my experience] they start opening up the groups.
So my opinion is that they are way to pricey for what you are getting and very limited on top of it. They started putting jackets on bullets that are shot over 1500 fps for very good reasons. Lee
