Ok finding load data for this caliber is really hard. The only stuff out there is for the hornady 220 and 270 bullets. That would be great but then I found out that the 220s are discontinued. I would really like to stay around the 200 -220 gr bulletin range. Has anybody used the Sierra 200FN. I've tried everything to find data and have come up short. Any help would be great. Can I follow the hornady data for the Sierra bullet or maybe use the 375 Winchester data?
