303 british wont stay cocked

i have a 303 enfield that has been sporterized when you pull the bolt back to eject load the firing pin immediately slams forward this started after i took the bolt out to clean the rifle i had this repaired once before everything was ok until i took bolt out and cleaned rifle i thought it was a sear before?

If I understand correctly, you unlock the bolt, and pull it back only part way and the firing pin goes forward. I don't see how that can happen.

Now if you pull the bolt back all the way and start to close it and the firing pin goes forward, then your have a problem either with the cocking piece or the sear. The sear may be damaged or something is causing it to not engage. Is the sear/mag catch spring in place and properly seated?

303

the bolt is pulled back all the way i push it forward before the head of the bolt seats the firing pin goes forward another question the front of the bolt that unscrews how much should it be tightened also it has a plate on the bottom to make it a internal mag which sear do you mean the one that holds the firing pin back or another

The sear is part #23
The cocking piece is part #8
The sear spring is part #22

The bolt head should be screwed into the bolt body as far as possible and still allow the bolt to close.

"...a plate on the bottom..." That sounds like a mag cut off. It pull out the side? Also makes it a No. 1 Mk III.
"...took bolt out..." You take the bolt apart too?
The bolt head is turned in until it stops.
Sounds like the sear is worn, the bottom of the striker or both.

Probably the result of another amateur "trigger job". Geez. Guys who can't turn on a light without directions think they know it all about guns!

grammer and punctuation is your friend

I am having trouble understanding, perhaps others are also.

your run on statement makes if very difficult

is your gun a "Cock on Closing"? as such the firing pin should not move until you close the bolt the last inch or so

is this when it slips? if so, DON"T FIRE THE GUN until it gets serviced as this could fire a round that is not fully in the chamber with bolt closed.

Sounds like someone tried to "Lighten" the trigger during the "Sporter" process and went hog wild
