Is there a preferred method of mounting a scope onto a rifle.
Assume you install the mounts and scope loosely, is there a best sequence for
nipping up the screws on the mounts and scope.

This might all be rubbish, but it's what I do:
1. put mounts onto dovetail and check the scope tube clamps are aligned
2. set eye relief (mounts on scope tube not bells - obvious!) and clamp mount to dovetail (consider not obstructing loading port/magazine and other parts of the action) making sure the scope doesn't touch the action/barrel
2. set vertical alignment of barrel and reticle (spirit levels) and tighten ring caps - don't overtighten
4. optically centre scope and shoot to see POI compared to POA. pack rings (https://www.bsaguns.co.uk/optics/scope-setup.aspx) to get close to zero - leaving minimal elevation and windage adjustment to get zero

Hope this helps.
Clean the rail, or dovetail with methelated spirit or similar product .
Do the same with the bases and rings.
Place the rings on the rail.
For a spring gun ensure to pull back the ring against the stop if one is fitted and gently nip up. On a recoiling rifle ie centrefire push the base forward on the stop as you tighten up
Remove the top half of the rings and set the scope on the bottom rings.
Replace the top rings and again just nip down enough to hold the tube but allow rotational and fore and aft movement.
Turn up the mag to max and adjust fore and aft for eye relief. You should see the whole of the sight picture without tunneling when holding the rifle to the shoulder.
Your rings can now be secured to the rail keeping them as far apart as possible but cleat of the ocular and objective bell tapers.
Set the crosshairs to true verticle, use a bubble level on the rail / dovetail and a plum bob to ensure that the reticle is true.
Nip up the back ring crossing from left to right , back and fourth little by little untill snug ensuring that as you tighten one side the cross hair remains on the verticle.
Repeat on the front ring.
Your scope should now have perfect eye relief and a vertical reticle .
Take care not to over tighten the holding screws on PCPs or rimfires. Spring guns and snappy centrefire rifles will require a little firmer grip but not raxing tight or you may damage the tube.
Hope this helps.🙂
