Finding the perfect barrel length

[Veteran]

5 shots from 300 WM at 100 yds with a skinny 24" bbl that vibrates like a piano string. If you reload, you can make the bullet exit the barrel when the muzzle is quiet. Or you could alternatively lug an 18 lb rifle around the mountains.

Nothing wrong with a shooter
Bob. All you have said is you have tuned and dialed this one in.

Bet that I can show you 100s with thin skinny barrels 28 inches long in 300 WM that look more like shotguns even with reloading.

24 inch bbl is not really that long......Id consider it middle of the road for 300 WM.

Id be curious what make rifle, and bbl diameter at the muzzle this is?

Also, what your pet load developed is for it in 300 WM including powder, bullet, and velocity?

Yes, sometimes even a rifle with bad harmonics can be cured by tuning the bullet exit time to suit the harmonic vibration through reloading or by tuning the barrel to the ammunition with a barrel tuner.

Nice group, and sure nuff a shooter.

What did that group look like with your first load or store bought ammo?
