Thanks everyone. I’ll try emailing companies.
I’m specifically loading for 7x57 and 257 Roberts right now.
I find the load data for h414 in the 257 varies quite a bit even when claiming to be p+ data. I think I’ve come across max loads of 43gr to 48gr and then some guys stating they have used up 49gr for 120gr bullets.
I’ve so far loaded up to 42 gr and it seems I have plenty of room to increase based on being able to load the bullets way out, the data I’ve come across, and the velocity I measured today.
More than ever before I’m looking for accuracy over velocity but in the past I’ve found getting the velocity up in most cases (literally the brass) will get the pressure to the sweet spot
