I have a 19" 300wsm 150 factory at 3100, 180s at 2950. That's enough for me.
Contemplating a .300 wm rifle but it's only available with a 26" barrel which I think is a touch long for a hunting rig. (this is not target rifle, hunting only)
At the very least if I pick this one up it will be getting chopped down to 24".
Not necessarily interested in squeezing out every last drop of velocity for typical hunting ranges so not worried about a couple inches.
What's the shortest barrel you would consider for a .300 wm ?
When I was hunting, I went through similar debate.... my conclusion was getting to the game was my first priority and the irony of setting up tons of gear for reaching way out, the vast majority of my game were inside 250yds... well inside.
So I started to lighten the load and went from magnums to 30-06 to 308 to eventually a 19" 7-08 with a moderate load. Animals fell as well as any magnum I had. Engagement distances could easily get out to 400yds IF I had the chance. The last deer I shot was around 30yds and the 7-08 did it's job very nicely.
Whatever hunting distances mean to you, work backwards from your impact velocity and thus internal damage. There will be a bullet to suit any scenerio from slow to fast. It surprised me how close the full range of bullets expand within their operational parameters.. and what I have seen on game, the wound channels seem to agree. Now fast combos did cause more bruising which on a couple of occasions ruined more meat then I was expecting... and that moved me to "slower" options.

I would think you would need to choose powder wisely with a short 300, ie faster burn. Heavy 26" barrel 300 wm is what I'm working up now with 215 bergers and H1000. So with different powders, very likely different bullets, you are wanting another 300wm to....... share dies? I like your thinking.
It's been debated many times, but extensive tests prove that the same powder that gives maximum velocity in a long barrel,
will give the highest velocity in the shorter tube as well. So, powder "juggling" is simply wasted time, IMHO. Eagleye.
Well, after reading all the speculation posted here,.....
Some of you may remember the Patriot 300 Win Mag wring-out from a while back. The factory 22" barrel had no problem at all averaging 3060 fps with 180 gr bullets ahead of H450. Here's the thread, https://www.canadiangunnutz.com/for...ag-for-400?p=13776794&viewfull=1#post13776794
Never did shoot any factory ammo in it, and it is now in a new home far away, getting ready to go hunting.
Recently got another Patriot 300 to replicate the testing of the first one. We'll see if No 1 was an unusually fast barrel or not.

19" barrel throwing 180s at 2950? Yeah I'd be happy with that. Cars to give details on the rifle? I'm assuming it's not a factory off the shelf rifle?
I wouldn't go any shorter than 24". 24" isn't bad to carry IMO.
