Performance Difference with New 1oz Load

Why was the 16 gauge 15/16th oz load changed to the new 1oz load? Will I see any difference in performance or speed with the new 1oz load? FYI-the 15/16th loads were awesome and just hoping I can expect the same or better? Thanks.

We have increased the weight of the 16 gauge Commander IDS PLUS to (1oz.) for better controlled expansion, deeper penetration, more energy down range with less pressure and recoil.
It is every bit as accurate as the Commander IDS lighter weight versions.
