Reloading 300 wsm question

[josephpark18254]

I currently have norma mrp and sierra 155 g tmk. Load data is almost non existing does anyone have any suggestions. I realize that there are other powders and bullet weights but I am asking specifically about any suggestions on the above mentioned. The closest my research brings me is norma mrp runs about 3 grains average higher starting load than the data that is available for norma 204. This seems to hold true across several loadings for quite a few different calibers so my intention is to do start working my load 3 grains higher than the norma 204 loading for same weight bullet. Amy suggestions?

First welcome to the forum.

I find that in these days of internet and email that an email to Norma with your intended propellant and component combination/caliber will usually net a safe factory recommended load if one is available. I reload for the 300 WSM but use Hodgdon and IMR propellants only. I cannot justify the higher cost of Norma for my regular shooting needs at this present time. YMMV

A lot of others have looked and few comments so there might be a reason no data is forthcoming. Just sayin.

For the most part you can use data for typical 150 gr bullets interchangeably with 155's. Just start at or near the starting load data. Once you approach max loads you may reach them with slightly less powder with the 155's.
