SCLID: Sudden catastrophic load induced disassembly
"SCLID": Sudden catastrophic load induced disassembly
It happened (case head separation) to a fellow shooter yesterday, at our outdoor range. Happily...no one was hurt, save for the shooter who had some wood chips blast his safety eyeglass face.
Rifle: M1917 Enfield rifle, chambered in 30-06
Ammo: His own 30-06 reloads.
I was shooting my Martini Henry Model12/15 rimfire rifle in the standing position, when I heard a loud Kaboom to the left of me, about 20 feet away.
He was shooting off the wooden benchrest. The right side of the wooden rifle stock was blasted out under the bolt. Magazine floor plate and spring was blasted out and laying on the concrete firing pad. Furthermore...another metal piece from the kaboom, traveled back to the right side of the shooter and impacted the aluminum handle of a broom, that was hanging from a overhead canopy pole --- About eight feet from him.
I don't know how to post pictures...but I did take a picture of the destroyed broom. It had an inch long by 1/2 inch wide entrance and exit holes in the lower part of the broom handle. The broom broke off the handle. The only thing blocking the possible pathway of the shrapnel...with my 2020 Toyota TRD PRO 4Runner (parked about 30 feet away) was the brass collection broom; that was in line with my truck.
Anybody would have been seriously hurt...if hit by that flying piece of metal shrapnel from the Kaboom...that I still haven't found yet.
So then I searched "case head separation" on the web...and I read that M1917's, 1903 Springfields and pre 64 Winchester M70's have a "cone breech", that makes for some "spectacular events"...involving case head separation incidents.
I don't reload brass yet...but I'm never gonna shoot reloads in both my own Winchester M1917 and my 1903 O3A3 Springfield --- That's for sure.
The involved shooter...does have another M1917 at his home. And they are very pleasant and accurate too shoot.
