Advice about pressure signs

[lazyengineer]

Yes. Gold Dot builds pressure faster than most cup and core bullets from what we’ve seen so far.

I wondered about that. I have a hunch that a hot load in a Gold Dot, may not be so hot a load in another. I feel like their jackets are.... sticky(?) in the bore. It seems like they love to foul and leave a lot of copper behind. It makes me wonder if the bullets drag more or something, as they go down the bore. Maybe I'm wrong, has anyone else noticed that copper patches after running Gold-Dot reloads seem to take more effort to get the copper out?
