Rawplug question

I tend to only use Uno rawplugs for most jobs (I always have a stock of them) but at times find them a little small in length. I have often wondered which of the following 2 methods are strongest.

At times the screw needing to be used is a little longer than the plug (yes I could use a longer plug fixing, but humour me) and I have either done one of the following.

1) Drilled the hole to the length of the screw and buried the plug to the back of the hole, therefore accommodating the longer screw (longer than the plug)

2) Drilling the hole to the length of the screw, placing the plug as normal to the face of the wall and pushing the screw through the back of the plug to accommodate the longer screw.

Now ignoring the fact that I could choose a fixture that fits the screw more appropriately (please), which of the 2 methods would you choose, or if you are adamant that you would never do either, which theoretically would you say is a stronger fix.

Please don't respond with neither and give me alternative methods. I only want an opinion on which of the 2 would be best.

Neither.
Lol, you made me do it!

I find the first option works best, especially in very old plaster that crumbles and before you know it, the plug is rotating with the screw.

That's interesting.
I've just used some in exactly that situation (screws longer than rawlplugs), but fixed into exposed bricks. I inserted the rawlplugs until flush with the surface (no further) and the screws hold firm.
I can see what you mean about plaster, though.

I have used both methods at different times and had no problems with either. I have never had a plug spin on me, but could see how it would happen if the plaster was weak. I suspect the first scenario is stronger, but was wondering what others think/do.

Technically, the plug should be at the front of the hole and flush with the wall surface. The lugs open and grip the wall when the screw goes through it so, once the tip of the screw passes through the end of the plug, it has already expanded to it's maximum (assuming the right gauge screw has been used). Although the plug works in the same manner when pushed deeper into the hole, when it is flush with the wall it supports the head/neck of the screw better, whereas it can have a little movement (especially when supporting heavier items) with the plug deeper in the wall.
As mentioned, weak plaster may make it necessary to insert the plug to the back of the hole.

BTW, great choice of plug. Once I'd discovered them they were all I would use - just wish I could get them in this country!

If all else fails, you can always order them from e-bay, or ask a friendly Brit to bring some over in their hand luggage

Yes. They don't weigh very much!

I tap plug to rear of hole and add another to front, just leaving plug at the front of the hole can mean there is no thread from the screw in it with some types of screw. [Not all screws are fully threaded].

Neither, if the screw\hole is longer than the plug I have I forget the plug and use cocktail sticks instead

Tend to lean towards your first option although other factors can come into play. I always try to get the plug fully into the brick ignoring the plaster so to speak. I've also done as foxhole says at times too. One thing to watch as well is voids, frog and holes in the bricks which if inadequately filled can prove poor to fix to . You'd notice that if the drill seems to go in easier towards the back of the hole.
