I kinda did this last fall. My big long range cannons get heavier every year so I looked at other options and shortenned my range to 650 or so yards. I wanted a light, easy/quick handling all purpose rifle to do it all. Would handle a wide range of bullets and have long barrel life. Ability to take all of Wyomings big game out to 650 or so yards and be a good rifle to poke a coyote. An inherently accurate round that did not require a muzzle brake
to be shot effectively at long range. Quick shots with a brake blow your eardrums out when no time to put in earplugs.
I put together a 300wsm with a 24 1/2 inch barrel and scoped it out with a 3-10 mil dot scope. It weighs just over 7 pounds scoped out. It shoots one hole groups at 100 yards with 150 E-tips at 3419 fps. With a .469 BC they do very well out to my 650 yard goal and the etips hold together to kill anything within that range. When a bullet holds together 95% of its weight it kills like a heavier bullet.
There are many choices and I can think of dozens but I am happy with this rifle and it is probably about as good as any. I have many wildcats off the 280 and 30-06 case that have similar velocities but one of my criteria was easily available ammo when on a remote hunting trip. So I chose the 300 wsm
. I can shoot this one bullet/one load setup for anything in Wyoming from coyotes to moose.
