Stumblebum, yes, that is the way it should fit. Just remember never pull the foreend away at the muzzle, always take it off at the rear first otherwise you will damage the draws.
As for the front trigger guard screw... it does next to nothing with regards to recoil unless the draws are loose... then it isn't the screw that has hold as the metal bush correctly fitted only allows .020" crush on the coachwood foreend by tightening the screw. (Yes, that figure appears in the fitting instructions, and there is a special jig/tool for measuring and filing the bush to the correct size.)
If there is movement at the draws then the next part the forrend has stopping it from moving forward is the bush. The foreend will not last long at all with the bush taking the force as the round surface acts as a a wedge and will split the foreend longitudinally from the bush forward.... tell you what. It's all a bit hard to fathom from descriptions, I'll do some pics and stick up hopefully in the next couple of hours.
First pic, the area of the front of the trigger guard, wood only, bush removed. Note the small area of wood around the screw/ bush hole where any clamping force would be concentrated

Second pic, the same shot, bush installed

Third pic, the same bush/ foreend from a low angle showing bush approx .020" below the wood line. The bush would be against the front trigger guard screw hole and the foreend would be in contact with the underside of the receiver ring and front of the magazine well, also the barrel knox. Locking the screw through the trigger guard will easily crush the foreend the .020" under screw pressure over the small area of contact until the screw bottoms out the trigger guard to the bush to the receiver. It cannot do any more!

Here's the same foreend. It never had the copper plates fitted. You can see the depressions either side of the middle where the sear lugs have contacted and impacted their way into the timber over time and firing. This shows the foreend relative to the action, does move forward under the forces of firing due to the barreled action moving back and the front hand holding the foreend against the recoil, which is mainly transferred through the butt to the firer. This damage can probably be minimised by pulling the rifle back into your shoulder with the right hand on the grip, and leaving the foreend sitting on your open palm... but that is just the way I shoot... others will have their own techniques proven for accuracy, but maybe not longevity of the foreend...

Next, back to the front trigger guard bush. Note the gap between the front of the bush and the foreend. This gap is almost as big as the indents where the sear lugs have compressed the foreend. The distance between the sear lugs and the bush is fixed- cannot change. So, whatever happens at the sear lugs, happens at the front trigger guard bush
Attachment 44802
Last pic... death of a foreend? No, it was doomed long before it got to this. The bush is now very slightly further rearward than the indents at the sear lugs. The combination of the bush not moving, the shape of the bush and the surrounding hole at the rear, and the loose fit at the draws means the forces absorbed at the bush have wedged it back in the hole and opened a crack forward the full length of the foreend

This rifle had always been locked up tight in the front trigger guard screw. In fact it was staked and very hard to release. It did have a little crush on the foreend, as prescribed, but that did not prevent what happened.
I suggest anyone who chooses to think otherwise regards the relationships of the parts discussed should conduct an experiment to prove these wrong.
1. Take the recoil plates out of your Lithgow foreend. ( This will simulate the gap giving loose draws like the pics above without actually damaging anything) :confused:
2. Ensure the front trigger guard bush does allow .020" crush on the foreend when the screw is locked up. :rolleyes:
3. Go and fire a hundred rounds of mkVII from the prone unsupported position. :eek:
4. Check if there is any forwards- rearwards movement in the foreend :yikes:
5. Check ebay for a new foreend. :crying:
