Not seeing any data from Speer using the 125gr TNT bullet in the 300 black out. I would assume that the Hornady load data would suffice but, then I am assuming things not knowing things. Anyone see any problems with this assumption? Have any of you tried this bullet in a 300 blackout cartridge? I will be loading for 2 different uppers, one with a 16” barrel and one with 7 ½ “. I don’t have any 125gr Hornady bullets to compare the Speer bullets to but the 125gr hp (#30192) would appear to be verry similar in shape, maybe not same in composition.
 
Thank you Marco, I was able to find that, but it refers to the 130gr PN2005.Was looking for the 125gr TNT PN4725 version. Seems to differ from Hornady's 125 in shape and design. I'm sure between Speer and the Hornady data I can come up with something close enough to load some test rounds, thought I'd ask the community for experiences before loading.

Judging by the responses, I'm on my own here.
