Jamming SBE

[scott27847]

I have a SBE with approx. 2500 rounds through it. I'm having trouble with bolt jambing. It ejects the empty shell, but won't spring forward to load new shell. When this first started a few months ago, it was only after 125-150 rounds that day at the range. My assumption was this was caused due to fouling from inexpensive low power shells. Howver, the problem is getting worse. Most recently it started jambing after only 65 rounds. This gun is stripped and cleaned after each day afield. Only the bolt assembly has never been disassembled. Could it be that a spring is already weak?

Are yo saying the bolt stays hung open?
Does it leave the new shell on the carrier, or does it lift the new shell and then jamb with the shell "stovepiped"?

Why haven't you disassembled and cleaned the bolt yet?
This takes about five minutes to do, and it's certainly overdue with 2500 rounds through it.

Have you cleaned the recoil tube?

New shell is on the carrier.

New shell is on the carrier. </font>[/QUOTE]I've cleaned the recoil tube. Never tried to disassemble the bolt. Looked like it may require special tools, and the manual didn't give instructions on how.

It ain't the spring in the bolt - they usually last the lifetime of the gun.

IMHO, it's cheap shells or a dirty gun or how you are holding the gun/not holding the gun or crud in the recoil tube assembly or maybe it's something else...

My top bet is cheap shells...

clean bolt..use better shells...make sure you are cleaning the recoil tube in the butt of the gun correctly....

Make shere that there is no junk in the carrier spring, also add a little oil the the pins that the carrier is attached to. If the carrier is sticking the bolt will not close and you will have the problem stated above Good luck
