The issue goes far beyond "brand name" consumer-minded considerations.
("Gee Alice, whay detergent gets your dishes so bright?")

Have you weighed these bullets? Have you measured their actual diameter (with a micrometer, not a dial caliper)?

You don't mention your particular gun specs, ie: throat diameters, bore diameter, presence of thread choke (or not?), etc.
Once you know that, you can then tune your reloading dies to match (with consideration given to the type of brass you use) so you're not ruining your bullets.

Without this info, you won't know where to begin as far as selecting a bullet, especially a cast lead bullet(!), is concerned.
