For me...good question. After 40 plus years of trapshooting, I'm thinking my LOP has always been too long. Maybe the reason why hard lefts from post 1 have always been the only problem targets for me from 16 and 27 yards.
Looking forward to opinions and maybe the correct way of determing correct LOP.
Two weeks ago I took a friend of mine to CG over on Marylands Eastern Shore. The gunsmith there dry fitted him to the gun. He looked at the way he mounted the gun. It turned out that he pushed the gun out and away from his body to shoulder the gun. To long a LOP. After the gun was mounted he looked at his right arm. He wanted his right elbo at a 90 degree angle or lose to it. After that he looked at the space between his thumb and face. I know ABSOLUTLY nothing about stock fitting, just passing along what I observed.......Dan.
Butch, length of pull isn't the most critical part of stock fit. Not seeing the lefts correctly is the problem. If you decide to shorten the stock go slow- maybe an 1/8" at a time. A little cut goes along way for some reason. Good luck- Dan
Ask some people at your club if they have old pads of varying thickness laying around. You can remove your pad and tape other pads on with duct or freezer tape. Or find a thin pad and just keep adding spacers till you don't bump your nose with recoil.
My rule of thumb is, what ever feels comfortable, as you will know what the correct lop for you is real quick. I am down to 13 inches and I feel that I have a lot more control of my gun now. I have always used velcro on determining lop.
I take the original pad off the gun and use different pads of various thickness. I then place velcro on the butt stock, and a piece of velcro on each pad, rather than screw the pads down on the gun itself.
It takes a lot less time and energy and this can be done easily while shooting, as each pad will not come off the stock unless you actually pull it off.
1" - 1 1/2" seams to be the common dimension. However, some shooters are "neck stretchers", especially during the stress of an event. Shoot quite a few rounds before cutting a stock. Length can be added with thicker pads, spacers, or even an adjustable RAD or GraCoil, but a thin pad is the safe way to shorten your LOP till you're sure it's right.
There isn't one set of numbers to reliably go by on proper stock length fit for everyone. Length of neck, thickness and shape of shoulder pockets, width of shoulders are all different.
The distance the nose winds up from the thumb depends on other variable's also and not a good indicator of a proper stock length at all! Head tilted forward or more upright? Comb height and body type determines the distance the nose is from the thumb??????
I wrote a blog piece on stock length over on itrapshooter.com. Take a peek at that too and let me know what you think? You can post question, replies or opinion there also.
To those saying that stock length isn't an important part of stock fit? Prove it with consistent recorded scores with varying stock lengths? That just ain't gonna happen day in and day out in trap shooting looking for consistency.
Try shooting your gun without the recoil pad. This is the time of the year to do it (if you live in the mid-west or north-east). It will let you see what a 1" shorter stock (in most cases) feels like without cutting the wood.
One thing I've noticed is it makes a difference what gun your shooting also.I began shooting a Browning sporting Clay gun.Got LOP comfortable at 13 7/8.Bought a BT99 ,figured I should set the lop the same.It was set at 14 1/4,removed a spacer to get it to 14",a little closer to what I thought it should be.Boy,did my scores drop after that,put spacer back in and scores came back up.Go figure,but thats the way it happened for me.Made me a believeer in trying a gun and working with it individually,not jumping to preconceived conclusions.
Lou- the LOP varies by which gun you are shooting- it isnt the same on each gun because there are so many other stock dimensions to include thickness of stock- template of butt, cast, height of comb, pitch- and one of the more important is grip distance and curvature
The LOP is really the least critical of any of those and you have that range of maybe 1 inch to 1 1/2 inches- you can figure that out yourself
But you always hear people talk about LOP because they dont really have any idea of stock fit at all
Thanks for responding to my question. I don't mean to jack the thread, but I often hear about professionals who will build a custom stock to your dimensions. I would like to find a professional who would work with me and my family to make sure our equipment is set up properly for fit . I'm in the Pacific Northwest .
