Is there a rule of Thunb ?

This link is for a tube gun chassis, but the adjustable buttstock may be somewhat similar. I believe he starts out with LOP, so you may not have to read the whole thing. I am tall with a long neck, when I lay down prone, My length of pull needs to be about 2,5 inches longer to keep my eye out of the scope.

It's all a matter of personal preference. Personally, since we are all shooting from Neo-SEBs(?), in the most part. I feel that the closer we can pattern our stocks to the BR guys, the better off we are. Except, for some reason, the BR's guys seem to cling to a sloped bottom rear stock, which doesn't make sence to me...as the more expensive FT-R stock maker's do, too?? But, each without using all the additional butt plate and cheek rest parenpanilla. My personnel preference is to have a plain rear stock with a horizontal trim on the lower rear, and save your money on the rest of the stuff, and use an exact LOP.

LOP is not that important for f class. It's not like sling when you're creating tension in the sling and trying to locate your head behind the sight. Just use what ever feels comfortable.

Short range Br stocks have to have 6 degrees of drop in the butt stock per the rules. In long range Br we dont, and very few are using stocks with drop, most are parallel to the bore. In FTR its done for making elevation corrections, but with the joy pods and elevation wheels I do not think its needed anymore like it was with non adjustable bipods.

I would say my average build is 14" collapsed, some 13.5" some 14.5" I do like a 3 way butt so you can position the pad to hit your shoulder squarely. I find I need to raise the pad and move it left slightly. I never use them for lop, you can easily build the right lop on the rifle without a 3 way. The reason the pad needs to hit your shoulder square is the same as in Br. Tracking. If the pad hits the side of your shoulder muscle it will push the butt to the left in the rear bag same if its too close to your neck it will push it right, you want it square in that pocket. Allows for less upset in the bags, faster shooting, and less chance of cross fire. Another reason to shoot with your shoulders square to the bore. This applies to bipod shooting as well. Build a good position and tracking will improve. I can watch my hits at 600 with a 9lb 28 Nosler, if my position is off Im looking 20 feet or more away from the target after recoil.

I believe 13-1/2" finished length is a fairly standard value. That said, there are a few things to consider. Are you planning to shoot free recoil or do you plan to shoulder the rifle? The eye relief requirements of your scope may dictate how you setup behind the gun. And what happens to your setup if you change to a different scope? For these reasons, incorporating an adjustable butt pad has always made sense to me.

Finally, your builder should be able to help you. If not, visit this Master Class link for some help.

I think I need to get "learned-up" on the process for setting up the three way correctly.
Upon recoil, I'm looking at the rubarb patch.

I'm the odd man out here. I'm 6'4" and have a 36" sleeve length. I have my custom stocks set up with a 15" LOP, which keeps me from having to adjust the plate out.

My buddies and I often shoot one another's rifle. Adjustability is nice on those occasions. We also let each other's children shoot them. Being able to adjust down to a short length of pull really helps on those occasions. Also for a new shooter (often a wife or girlfriend) who is just short.

I guess I've always seen a rifle as a tool to be used by a number of people rather than something for just one person.

That's the way the Army, etc, also looks at it. Why don't you just take the LOP off an M1, M14, or M16 and be done with it?

It's the 21st century. Most rifles currently fielded by the US military have adjustable LOP, including the M4, M24, M2010, Mk 21, and M40.

 

[XTR]

Most people are good with about a 13½ LOP before adjustment, unless your on the short end of the data set, then you might want a little less. I'd probably run mine longer but I really can't get the scope back any further for head position.
