Should I use magnum primers with IMR 7977

Thanks for the reply, I'm currently shooting the 175 ABLR's in my 7mm with RL22 and it shoots great, I'm just having problems with the RL22 being temperature sensitive. And IMR is talking up IMR7977, so I was thinking of trying it out. Are most guys using the Nosler reloading for staring loads.(they only show the 175 Nosler Partition bullet).

I read somewhere that Nosler said to use the data for their other bullets of the same weight. I can not remember where I read that but that is what I have been trying to do.

Thanks, I'll just start from the middle point and go from there.
