I notice that load data specifies the manufacture of the bullet along with the weight. What is the difference between a Speer 160g and a Nosler 160g bullet with regards to charge? Is it OK to use load data for a Speer 160g for a Nosler 160g bullet?

I just started hand loading for my 45-70 Trapdoor Carbine. All the factory lead black powder ammo I tried produced tumbling bullets. My rifle has a good bore in specs so I knew I could create a load to produce accurate round holes in my target. After many iterations I found the Nosler 300 Gr...

I was wondering if anyone could give some advice on handloading this particular bullet. I'm new to this forum I own a remington 700 that's been customized some and I would like to do some hand loading for it.

Just getting started reloading the 300wsm and cant find any data for this combo I will be using win nickel cases, win mag primers 150 gr nosler silvertip and reloader 17 any help would be appreciated
