Geoff,
Lifes to short mate...............not a rehearsal so thought I better do it

Very true, you can spend a long time dead as a bloke once said to me........... anyway guess it brought some memories back looking down the range ? maybe some not that pleasant, but think the good ones will always outweigh the bad......

Couldn't agree more guys, we have to enjoy shooting while we can, owning and shooting an L1A1 is a pleasure. Who knows what's next on the ban list, one things for sure, they never give us anything back, so enjoy it while we can.

I think those of us with straight pull L1A1's can easily prove they are not rapid fire rifles by the fact you have to stand on the cocking lever after about five rounds because they have gone into hard extract mode

[Gil Boyd]

David,
I am going to try mathematics next time on the range. I was firing GGG 7.62 on the video and as you say the sixth round was a hard extract.
I am going for 145 gn .308 next time to see the difference, certainly wouldn't advise 200 gn.
Wait Out on the result which I can video again.

I never quite got my head around why the straight pull L1's became difficult to extract. I'd like to put one on the enfield layer with the cover removed plus fil it with a high speed camera at Shrivenham to see exactly what is happening within. After all, the breech block is locked down and held down by the carrier (which is why the carrier is a proofed part on the L1A1). Carrier is drawn rearwards, lifts the BB, creates primary extraction...... so what is the prob? First Q is this. During the hard extr phase, say after 8 rounds, does the BBcarrier retract slightly before it tightens up? That would indicate that the BB is trightening up and won't lift after the mechanical safety. If the BBcarrier is tight from the word go, it would indicate sumfink else inn'i

Answers to those queries please chaps........

Well you can't blame it on gas

[Gil Boyd]

Peter,
If you are baffled I am sure the rest of us are too.
Let me try these Winchester .308 145gn out on it, as I think its a round/case issue where the neck has been shimmed on the new barrels, could be wrong!

[Peter Laidler]

............the neck has been shimmed on the new barrels,

I don't understand that bit Gil. The first answer we/I need is as per thread 16

sumfink else inn'i. You and your technical terms Peter
When I bought my first example, I tried Privi .. The action was absolutely solid, felt like the BB/BC was welded solid with zero movement.

It took resting the butt on the firing point edge and a technical tap with a rubber mallet to the cocking handle to unlock the action.

This was addressed when I swapped the Privi for GGG and no more problems.

Seems to be a common problem, with a common cause, that's despite a myriad of different barrels with different chamber cuts..

Reason. The common consensus centers on thick walled civilian .308 ammo that adheres to the chamber walls and sticks like money to my Brother in Laws wallet (believe me that sticks tight).

The thinner walled mil spec 7.62x51 would appear to spring back, allowing the case to unstick.

The 7.62 chambered AR10 derived Rifles appear to suffer less, perhaps down to the rotating bolt unsticking the case?
