300 WM with 20" need advise...

"Gonna go out on a limb and say striker barrels under 15 inch vs a 20 inch tube are comparing apples to oranges." comfisherman
Yes it is a bit apples to oranges, but it shows the fact that this has been done to a much more extreme level and it works within reason. That's the whole point I was making. You can not expect exactly the same speed as a longer barrel, but the sky is not going to fall either as some assume.

You should read all of this article before going on with your plans. It is good stuff.

But no bit of information was, Virgil believes, more valuable than a little advice Jim Gilmore passed along. Jim said a barrel MUST be 21 3/4” long for optimum accuracy. That precise length, he stated, sets up a vibration pattern that duplicates well from shot to shot. Virgil faithfully followed that advice on his guns.

After reading this I would not have a barrel less than 21 3/4” if I was going below 24” to 26” range!
Seems it is a lock....milage may vary!
Good luck.

Odd, 22 inches was where I settled for my stubby 7 rum experiment, well 21 7/8".

Lefty, I totally agree that just because we go under 24 inches the world doesn't stop spinning and the sun explodes. Many of the sp fellows are launching bullets with a degree of precision that I cannot obtain in a 29 inch rifle. If I really wanted to stretch my legs the longer the barrel the better for me personally. But my 17.5 inch 270 has become my favorite rifle, the I'll be re-barreling it soon at the rate that its been shot lately.

Is that measurment of 21 .75" measured from the bolt face?

I'm contemplating a 20" 300 WSM to hunt suppressed. A little less powder consumption than the 300 WM, more compact, and still maintain great 30 cal performance.

Never thought about it - was not involved, but I would check out what the smith standards were back in that day before I cut one down, and go with that. I never did any of this but close the bolt and slide a wooden dowl down the tube -mark it and measure the distance is what I would do. Are you cutting one? If so what other way would you use?

So much game...so little time.
