Conversion of a 40X into an ARA bench rifle

I acquired a rimfire CMP 40X (heavy barrel) and would like to convert it to an ARA bench rifle. I would prefer to avoid making beginner errors (and thus avoid their associated costs).

What should I replace, have smithed, install, build, etc. to have a sucessful conversion?

Rebarrel?
New bolt?
Replace stock?
Rings/Ring mountings? (1 piece leopold with windage?)
New trigger group? (Jewell?)
 
save action..toss/replace all the rest.

mortgage home, put kids and wife to work..cuz your ammo cost for this year will be a couple grand or more...more is better:D:D
 
Start with the stock/good bedding job, and a trigger. Clean the bolt and if it doesn't have an unusual problem, it will be fine. Bases/rings are pretty standard and don't take much thinking. The barrel will make the difference between a winner and just a gun on the line but won't do you any good until you have the rest done.
 
+1 on the bedding and the Jewell. As to rings if you have the Leopold single dovetail bases order the extra high rings. Some of these 40X base mounting screw holes are off center(yours may not be) and the windage on the rear will solve that problem. James Pappas made me a 40X top for my rest so that I can shoot a standard stock. I like the Weaver T36 and see many of them on the line. Dan K has a new shipment of Eley:D You are going to have a lot of fun!
 
Shoot it before you rebarrel. Some of the stock barrels shoot exceptionally well. I have a heavy barrel that shoots very well and Danny Keeney had a standard barrel that shot well.

For shooting bench rest, you will almost certainly need to restock and drop in a new Jewell trigger. Make sure you get one with the bolt release. Sinclair has the scope bases with the dovetail and I think I've seen some bases for Weaver mounts but can't remember where, possibly Brownell's. Don't forget the tuner.
 
jewell tirgger with bolt release, you may need slight inletting. weaver bases #35 and #36. I use warne ex-high split rings part#203. make sure the tuner screws are backed out completely and the barrel is free floated. if it shoots well then a bench stock and bedding. lastly a barrel and tuner if the barrel is good and thats a possibility then a tuner. that way you don't end up with an enlarged bored tuner in case of barrel replacement. you almost have to test along each step and decide on your investment. the 2 most likly to improve accuracy is the jewell trigger and free floating the barrel.

Shehane Baby Tracker stock (read link), yes those are wheel weights, you can't add weight to that tuner because its not threaded and I was playing with the weight.

I did not shoot at all last year, but I have won some matches with it. This is a thrown together starter gun that some great friends of mine helped me with to get started in rimfire BR. I think my best target is a 2300.

You forgot second mortgage on the house to buy several lots of popular ammo to see which lot# it likes. Sell the rest to buy lunch at Mcdonalds. :p
 
That is a nice looking stock. I've seen the Indian pattern and they don't really do much for me but I like the snakeskin look. How wide is the forend on the Baby Tracker? Thanks
