Re: Help Which 7mm 7wsm 0r 280AI 7REm mag
I have never owned or loaded for the 280AI or the 7mm WSM.
I have done extensive loading for the 7mm Rem Mag and the standard 280 Rem.
For deer hunting in Rem M700 KS Mt Rifle 280 Rem I went with the Nosler 140gr BT and it performed very well. In another 280 Rem I have it is a old 1912 Styer (M98) that was rechambered from 7x57 to 280 Rem. The old stepped military barrel refused to shoot the anything under 160gr. I settled with 162 Hornady SPBT's and it shoots them very well. In the remington - I never shot anything other than that 140gr load.
In my Mauser Model 3000 26" barreled 7mm Rem Mag I have shot a bunch of different stuff. In my rifleit likes H4831 and a lot of it. I won't post my loads openly but if you would like to know what I am using privately I would gladly share them. This rifle likes the Speer 145gr SPBT, the Hornady 154gr SP, and the Sierra 160gr SPBT. Based upoon what I have seen in this rifle there is not a thing it will not shoot well.
I have also worked with a brother in law's Browning bolt action in 7mm Rem Mag It shot really well with most everything we put thru it. Same with Remington M700's.
My point being I have found the 7mm Rem Mag to be very well behaived and easy to develope loads for. This would be the perfect cartridge for a newbie to reloading to begin with. The only easier cartridge to load for in my humble opinion would be the 308 Win.
Good luck and have a great time. Partner with an experienced reloader if you can, most of the manuals have been lawyerized and published loads are down loaded.
