I gotta get to work..........but.
The rear locking lugs is part of what makes the 788 accurate. Especially from hunting positions. Super fast lock time. Not as important from the bench.
But having the lugs in the rear allows for bolt compression. The entire length of the bolt compresses when fired.
The 22-250, in particular compresses. A lot. The pressure on a 22-250 is about 20% more than a 223. 65k versus 55k
When the 22-250 is used for something like prairie dog shooting, they get hot.
A lot of guys reload 22-250 hot.
So, you have a hot gun, running high pressure ammo, and to make it worse some guys only neck size the cases. The bolt compresses. Now you have a stuck case with a bolt handle that won't budge.
The bolts handles are brazed onto the bolt body.
Out comes the hammer or 2x4.
And this is why you see a lot of nice 788 rifles, mainly 22-250s, with no bolt.
I have been shooting 788s for 30 plus years. Have a closet full of them.
Any mechanical device has limitations. These are great guns. You gotta respect this limitation.
