I think I recall Lucky Gunner being up front about that in their intro materials. To be fair to them, it’s prohibitive both cost and logistics wise to use ordinance gelatin to test the huge number of rounds they’ve tested, so if we want that huge array of tests, we’ll have to settle for a compromise (for now). Their use of clear gelatin still allows comparison between the bullets they tested using their test results, even if it doesn’t allow comparison to other tests.
That said, yeah, getting an idea of what the cited loads are doing would require comparing their results to, say, how 9mm HST or Gold Dots did in the Lucky Gunner tests to get an idea of what’s going on.
