Francis is correct, as usual!
You just have to shoot them to know. Most hand swaged bullets are good bullets but there's some difference (don't know what and neither do you) in the individual rifles, powder, load, etc,,, that cause one bullet to shoot more accurately than another in a particular rifle. There's not enough space on the internet for me to continue to write but that's it in a nutshell..."a good story" so to speak.
One other thing...Don't make any decisions using a rifle that won't shoot well with any bullet.
