Here is the question :
I am ordering a new Beretta 682 E for a friend who is beginning to learn international skeet down here in Brazil. He has little experience and he is using my ASE gold by now and my stock has 35 mm X 50 mm drops plus a 37cm LOP. He is doing good and he says that he sees about 1 cm of rib when he presses 90 % on the stock. He is taller than me and I feel he needs a longer stock ( 38 cm + LOP )) .
I will order his new gun from Beretta Italy but if keep the same drop ( 35 mm X 50 mm ) BUT increase the LOP to 38+ ,will he see the same amount of rib that he sees on my gun which have 37 cm LOP ?
Thanks & Regards

The 35mm x 50mm drop you describe is fairly “straight” but it does slope rearward somewhat. If all things are equal, lengthening a stock that is not parallel will move the shooter’s head to the rear and thus down. He will see less rib.
However, things are not always equal. If your friend has a longer/shorter neck or shoots with his head further/less far forward, he may not place his cheek in the same position that you would. Additionally, he may cheek with more or less pressure than you use. He may not even cheek in the same place on his face as you do. It’s a fact that a given stock of certain dimension can shoot very differently for one man than another.
Still, if he likes your stock height the way it is now and will only adjust the length, the 15 mm slope on your stock is shallow enough that there won’t be a great deal of difference. Remember, your stock drops 15 mm over a 37 cm length. That’s less than 1mm every 2.5 cm. For many shooters that won’t be noticeable. For some it will.
I don’t know how much rib you like to see when you shoot, but for me 1 cm would be too much. I like much closer to 3~4 mm as I don’t float my birds. With 1 cm I’d have to float the bird.
An additional problem is that if your friend is new to shooting, his style may not have fully developed. The way he mounts and cheeks the gun today may change in the future as he learns the game a bit more. Still, it’s always easier to lower a stock than to raise it because you have the option of cutting and refinishing in addition to the option of bending.
What I’d do is to take your gun and temporarily add length by inserting cardboard or plastic spacers between the pad and the stock. You may have to use longer screws, but you can also hold things together well enough with masking tape. Get the length the way he likes it and then see if he has the sight picture he wants. If so, then you can duplicate your stock, but with additional length. If not, then you will know how much lower to order the stock.
You can do all the calculating you want, but nothing beats temporarily altering a test gun and then shooting it to arrive at the right stock numbers.
