Stock straightness and tracking (video)

[Alex Wheeler]

Finally made another video. I have been asked by a few to do one on the adjustable rudders I install in stocks and what they do. Sorry for the quality but you get the idea. Its simple, if the stock is straight it will stay on the X when you slide it back. People give too much importance to the bags. If you carefully slide the rifle back and the crosshair falls away or lifts away your stock is not straight. Bags are more important when actually firing the rifle as they have to manage the violent recoil. And if the croshair never leaves the X it doesnt have to find its way back and they track!

I misspoke in the vid about shimming the front, should be shim the back. The white box on the 1k target is 4 inches. I did move the stock a little right when pushing it foreward as you can see. I recommend pinching the stock with 2 fingers and carefully sliding it straight back when doing this. Not easy with a camera in one hand

Had one of your rudders on a Bostrom stock with a BAT. Tom Anderson played with it one day. He sure did make it track.

Well I sold the rifle to a fellow in Texas. Turns out it may have been the best shooting rifle I ever owned. Tom has ragged on me near each time I see him about being so dumb as to sell that.

Your stuff works, ask Steve Kraus.

I have my rudder tracking perfectly left right. Waiting on a new front bag to make final adjustments on the vertical, but will practice with what I have now. Thanks Alex for your help, not only for me, but for all of the competition shooting community. Great job!! I'm sure the MT hunters are benefiting also, ha, ha.

Now, watching Tom shoot that 10 shot string was poetry in motion. How the heck are you going to beat that

Thanks, Alex; you said that you would make this video and you did.

Thanks for posting that Alex. E

Do you sell just the rudders, or is it only part of your stock?

Thanks

I make the rudders right now. I am going to have a bunch run on cnc for the Mcmcillan stocks when the mold is done. At that time I will sell rudders. Check with me in a month or so.

This sounds like a great idea

Alex, When I first started shooting IBS I was told the rear of the stock could not be parallel with the bottom of the forearm. Your rudder would seem to make it parallel with the forearm. So I tried to find rules on stocks in the IBS rules and couldn't find anything about any rules on the stock. Was this a rule at sometime and is no long an issue. Or was I misinformed to begin with?

Your Rudder sounds like a great idea!!

 

[Alex Wheeler]

Short range is a 6 degree angle. In long range we can be parallel.

Cool video about tracking. I appreciate you taking the time to make it.

A month? I thought CNC would speed up the process. What's taking so long??

I was waiting for a new front bag before doing the final rudder adjustment. Screw it, I could not wait. Tuning session on Tuesday resulted in the rifle tracking straight back. I mean straight back. Cross hairs never left the exact center. It took a total of 0.050 shim under the front of the rudder. Mistake was not going big with the shims or adjustments. Better to go big and see, rather than small incremental additions. Horizontal takes about 5 min to get perfect. The vertical took me almost 30 min. Next rudder will take less than 15 min total to tune. Some may argue that it is not that important, but hard to argue it isn't better. Now seriously thinking of adding them to my f-class rigs. This rudder was on a dedicated 17# bench rifle.

Mcmillan is making the mold right now. They will have 1/2" wide aluminum rails in the front and will come standard with adjustable rudders. Once they start making them wait times will be down considerably. I am super excited for the Mcmillan version to be done! I will be trying to keep them in stock and will offer blanks if you want to do your own work. Until now I have not sold blanks as I cant get enough for my jobs. I do expect these things to dominate

What are we talking for price? And what do they Weigh.

[Alex Wheeler]

I'm hoping they stay light, 3.5 with the rudder. I don't know pricing yet, but I promise they will be the best deal going, not much more than a st1000, and they will come with rails and rudder.

Their is no reason for a adjustment other then evelation . If the stock is straight and the action is installed straight with stock . One other thing the bore must be timed at 12 or 6 for bullet to exit straight with the stock . The rudder then would only be adjusted vertically for the different evelation in bag hight or evelation your shooting . Straight stocks properly bedding and Barrel timing is where most of the stocks go wrong .
Adjustable wings is a better choice in most cases . Larry

That is OZ. I hope, never make weight in pounds!

Nobody weighs a stock in OZ. LOL. I think my new one is over 4 lbs. But the length is want makes it heavy. 40 inches. Makes the barrel look short. But it makes it track nice. Matt

Funny stuff....your input here really shows how little you know about Benchrest.
