Hi I'm new to this. I bought a 338-378 a couple years ago. It came with 6 boxes of nosler custom rounds with 225 gr accubonds 3253fps. Nosler doesn't do the custom rounds anymore and can't give me any info. And they shoot very well with my gun. I took a round apart and it appeared to have imr 7828 powder 110gr. Looking at threads I haven't seen many people running this powder and not nearly that much powder with it either. If anyone has some load recommendations I would like to give it a try. I do wanna stay with the 225gr accubonds. I'm shooting a 338-378 accumark rc. I believe 1-10 twist. Thanks
 
If it's 7828 it's 6 grains over max in the latest manual. Henderson or maybe Choice ammunition my have something your looking for if load development isn't an option

Ya that's what I noticed too and didn't want to load anything without any type of advice or try and go with something that people are using. That's if I can find the powder
 
This is some data from my 338-378 and IMR7828ssc with 225 accubonds
