.243 load
I’ve went with different brands and bullet types before with my .243 and .308 staying with the same bullet weight, same charge weight, and still been in the same ballpark groupings. Mind you I don’t competition shoot or anything, if it groups sub MOA I’m happy.
I don’t go up to max loads either so it gives me that bit of forgiveness.
When I start changing powders is when it gets groups all over the paper.
Just my experiences.
