I replaced the bolt on my old 700 because some idiot had 'upgraded' to a Sako extractor. Bolt has been sitting in my shop for awhile.

I since the bolt is useless to me and I would never sell it to anyone, I thought I would see how well the bolt handle was attached.

I held the bolt body in my padded vise very tightly... and proceeded to smack the handle with a heavy dead blow hammer... length wise with the bolt body. One smack in one direction, one smack in the other direction.

I did this for awhile gradually increasing the force. Finally I took a two handed swing and off it came, leaving part of the handle still attached.

Back in 62-62 the factory stuck these handles on very well... I hope they come back with that quality.

Had one come in, had been beaten on from below, trying to get the bolt to rotate to unlock. The handle had peeled and then snapped, not unlike this one. I heated up the bolt to free the remaining piece, straightened things out, welded the handle pieces back together, refitted the handle to the bolt body, and silver brazed it back on. The ones that have failed generally show that the original induction brazing was far less than 100%. If the brazing was done properly, the handle tends to break, not just detach.
I've seen Mauser bolts with the handles broken off. Some of my customers treated their rifle pretty hard.
 
Harmonics/vibration removes the handle.

10's of thousands to date & heat was never used to flow the silver braze.

Early 4,5,6,7,A,B,C prefix serial numbered receiver bolt handles were heat treated/tempered,hence the purple-ish handle color.

And as pictured,they break at the extraction cam surface & leave the finger strap still attached to the body.

Early 40X rimfire bolt handles had an 1/8" pin to locate the handle & were copper brazed to the bolt body.

Cadmium silver braze(straw color) as used to C prefix receivers has better capillary action than the cadmium free silver braze used presently.

Sounds like my load development procedure at the range.
 
Actually, this is the same technique used by the owners of most new 700's since they have no primary extraction built in. They should have come with a hammer attached.
Dennis, I have come up with a system which will positively retain the Sako extractor in the event of a ruptured case or severe overload. When I get the rifle done, I'll send you some pics.
 
Looking forward to the pictures Bill.

And hopefully the "new" Remington owners will address the extraction cam problems...
 
Any OEM Rem "short cam" handle as I've coined them from 2006 "G" prefix serial numbered receivers to current production RR prefix serial numbered receivers will have the bastardized handles.

Physically & mechanically impossible to TIME for primary extraction....unless reworked.
