Another vote for leaving them alone.
I can attest that 125grn bullets are not the same.
If you look up my thread asking the question "who to believe?", we discussed switching bullets.
Along with that, I can also describe the pressure issues I had with Hornady SST bullets and charges used for other bullets of the same weight.
I used published data from the powder manufacturer for a different brand bullet with SSTs of the same weight. It turns out that even the starting loads exceeded max loads published by Hornady. I had ruptured cases and blown primers.
And, incidentally, my experience was with .300 Blackout as well.
Here's the thread I mentioned: Data: Who and what to believe...
Clarification...in that thread I wrote that I didn't have pressure problems. That is incorrect. Upon *close, careful* inspection of the brass, I found the signs...and when I dumped them out of their zip-closure bags, a couple primers fell out...the signs weren't immediately evident when i checked them at the range.
