That's great advice. In fact, if someone wants to quickly learn about reloading, they should get several different manuals. Most reloading manuals contain articles that explain lots of helpful info for the new reloader.

Reloading manuals from bullet and powder manufacturers seem to be the very best. It's also good to verify documanted loads between the different reloading manuals for an even better understanding.

Hey man, welcome to LongRangeHunting. Good choice of caliber, bullet and bullet weight. I have never used the GK but have shot a boat load of the 150gn Nosler Ballistic Tips through the two 7Mags that I owned.
My Remington Sendero liked the 150gn pushed by 67gn of RL22 and CCI's BR2 primers. My 700P liked the 150gn NBT pushed by 63.5gn of IMR4350 and Remington 9.5M primers. Both these loads gave me sub 1/2" groups and have been the demise of many a creature.
Check out reloadersnest.com, accuratepowder.com, alliantpowder.com, hodgdon.com and ramshot.com. All these are loaded under my favorites for quick ref. Good to have so you don't have to buy all the reloading manuals.
Hope this helps in your endeavors and again, welcome. JohnnyK.

Both of the 7 Mags that I reload for, dearly love Retumbo. Consistent, fast, and accurate.

Try the MKBT 175 with 63 grs of RL-22...this is what I shot at 1000yrds matchs and done well for me. I also shot the same load for deer killing and tactical shoots.
