I'm just getting into reloading for my .300WM. I've got the Sierra 2nd Ed. manual from my FIL and I've gone to the powder and bullet manufacturers websites, but I'm concerned that I may not have all of the appropriate min and max load data that I need given the bullets and powder I purchased.
Here are the components I have:
Powder: IMR 4831 and Reloader 22
Bullets (all 180 gr.): Nosler Ballistic Tip, Hornady SST, and Sierra Gameking
Brass: Winchester
Primers: Winchester Magnum Rifle
I bought these components after reading THR and other sites - these seem to be some of the most popular bullets and powders for .300WM.
Here is the load data I have:
Sierra Manual 2nd Ed.
For 180 gr. spitzer boat tail: IMR 4831, Start 67.3, Max 74.6
IMR Website: 180 gr. SPR MT-SP, IMR 4831, Start 69.0, Max 74.0C
Nosler Website: 180 gr. Ballistic Tip, RL-22, Three loads listed - 71.5, 73.5, and 75.5.
Here are my questions:
Do the loads in the Nosler website represent the min to max range? The velocity they list for the 71.5 gr load is 2928 fps. This seems too high for a min or a starting load. What charge of RL-22 should I start with?
Can I interchange these bullets with the load data that I have? The Sierra manual data clearly applies to the SGKs, but can I use that data for the SSTs and the Nosler Ballistic Tips? Can I use the SGKs and SSTs with the Nosler loads?
If the data I have is insufficient, I would appreciate any data that you all can offer for the bullets and powder that I have.
Thanks.
