I bought a large rifle case at the Northern Shooting Show (SKB i-Series) which was secondhand and the foam fitted inside is for a military metal detector and accessories. As I’m not a ‘detectorist’ I’m looking to replace the foam. A kind chap on this forum directed me to a good online site called E-Foam which is where I’m going to buy it from.
My question is, for those of you who have professionally (or even not) fitted foam, what thicknesses have you got the foam layers? Obviously a base layer is required for the bottom of the case, I was thinking 40mm for that, which leaves me 75mm to take the foam up to the height of the lip of the bottom half of the case. Do your cases have a base layer, then a single layer you cut to the shape of the guns/equipment fitted, or are their multiple layers, and if so how thick is each?
i.e. 40mm base layer (no cuts, or perhaps just small holes for charging handles etc to stick into) and one 75mm layer that is cut to the form of the guns I put in OR
40mm base layer, 1 x 35mm layer and 1x 40mm layer, both cut to form OR
35mm base layer and 2 x 40mm layers?
Also, when you gun is placed in the case do it protrude above the lip of the case, so it is pressed into the foam on the lid (and therefore the base layer of my case would need to be deep enough for the guns to be proud of the foam), or is it entirely contained within the foam? I’m just thinking if the guns do not contact the layer on the lid, any lateral movement would have to be absorbed by the foam around the gun, rather than the foam around the gun and the friction force from the lid?
Any help (especially photos) would help
I believe this is the case I have

And before someone suggests getting the foam from the case company, they want more for the foam than I paid for the case!
