Thread: 300 win mag

Both 7mmRM and 300WM will do what you want. So will some non magnum calibres 7mm or 30cal. (eg 3006 or 280ai or 284win)
Availability of ammo is fickle & sadly getting worse. Availability of suitable ammo/pill for long range & as op above stated .... shoots accurately in your rifle. Who knows ? This month you might be able to get 30cal, but 3 mo time it might 7mm ??
Really need to reload for the long range, & even then you get issues with component supplies.
But before you outlay a bunch of $$, have you shot either calibre ? and in the brand you think you might want to buy ?
300WM is a significant step up in recoil and muzzle blast over 7mmRM. Stock design, suppressor or brake will all impact this as well. In order to consider shots on game at 400+ yards, the shooter + rifle need to be capable of consistent sub moa accuracy.
I would make my investment in rifle based on what I can shoot accurately and is pleasant to cart around the hills, rather than the temporary availability of ammo.
