Loading for 300 Win Mag

[Reloadhby]

I always hear of peoples secret load for 300 win mag being reloader 22 and 180 or 200gr bullet, but I just never remember the charges

Hot or not, 70 grains of IMR4350 is the sweet spot for this rifle. I loaded up 4 more rounds to see if the last grouping was just a fluke but evidently not.
I’m also crimping every shell to ensure consistent case neck pressure.

I'm late to the game, but that load will hunt! Hopefully I'll hear about it's effects on deer this season. 180 Accubond, right?
