Rebarreling Question

[haugenna]

I have a Tikka T3 Lite in 300 Win and I want to make it a more accurate hunting rifle and still maintain the lightweight rifle.  

I want to put a match barrel on it.  I am going to use a gunsmith to do it.  What types of things are they going to do to the gun and barrel.  Square the action, thread the barrel, chamber the barrel?  What else?

I plan on shootng 175 Bergers in it and I am looking at using a Lilja match grade barrel.

As you can see I am in the early stages.

Any and all advice from people who know how to do it, what to do, and have done it in the past, is much appreciated

To address your PM, here is my project. I rebarreled this thing.  I bought the action for $150 at a gun show.  It was a standard bolt face.
I took it to Bechmark Barrels and they made it a 300 win mag.  They squared the reciever, opened up the bolt face to a magnum, lapped the lugs, put in a sako extractor and barreled it.  I went stainless with a varmint contour with flutes and a brake.  This is the stock I use for hunting because it is 3 lbs lighter than my Bell and Calson stock I use for long range and tactical shoots. They also bedded itfor me and bedded the scope.  
It all came to about $1200

You can get yours squared, lapped and barreld for I think about $500. You would have to call Ron to find out.  He could tell you more.
My friend, who is an auto body master, helped me with te custom paint job.  We like duracoat.

It depends on how accurate you want it to be.  Getting a 300 Win Mag to be very accurate specially a light weight rig can get expensive.   What do you plan to do with this rig?  If this is going to be a long range hunting rig I'd kiss the light wieght idea goodbye, your going to have to shoot it alot doing load developement and learning to shoot it at distance.

I guess my question would be, how does it shoot now? Tikka's are known for being pretty darn accurate.

First thing I start with is a trigger job. Possibly an optic and optic mount upgrade  You'd be surprised at how accurate a rifle can be when the shooter can really do his part.

To answer your question directly. No bore is completely strait through a barrel. It actually bows, or spirals. The smith may recut the chamber so that the lands and throat are straight with the axis of the chamber shoulder then cut the heal of the barrel to line up with the face of the action and bolt. Target crown. High quality stainless one piece scope mount and rings. Not aluminum. You give up a little in weight, but gain in reduced flex. A belted magnum head spaces on the belt, and there's a tollarance for factory built rifles. A smith will most likely 'adjust' head space to be a bit more precise.

That's just a small part of it. Your average smith does not do this. You'll be looking for a smith that is also a long range shooter himself. You cannot expect a light rifle/barrel to be as accurate as a heavy target barrel as the light one will change tension throughout it's length as it warms up from shooting. But many of the same tricks used by long range competitors can be incorporated into the build of a light rifle so that it's first 'Cold Barrel Shot' is consistant with it's last cold barrel shot.

AWS,

Out of curiosity, why would I have to sacrifice the weight?

Rob,

What kind of velocity are you getting and what is your load data? Length of barrel?

It shoots pretty good.  MOA.  I want to cut that in half to 1/2MOA.  I understand the heating up of the barrel and affecting the group and using a heavy target barrel will get me more accuracy.

So the question is, do I throw more money at the current setup and square all of the above up with the factory barrel or throw money at a match barrel along with squaring up the action and all the above? 

How important is the stainless mounts and rings?  I already have the LW Talleys on there

Thanks for the info jack.

My rifle as you see it is 13lbs.  16lbs with the other stock.  A heavier barrel is more stable thus more accurate. I have a Rem 700 Mountain Rifle in .270 with a skinny little barrel that with shoot a 10" group at 200yards

Heavy barrels are more accurate and handle heat longer.
A good quality, higher magnification scope will also add weight.

I am not sure what velocity I am getting.  I change my loads so much I am not sure.  I think its around 2900fps. I have found that 190gr JLK's and Berger 185's and 190 shoot the best from my gun.  Right now I am loading norma brass, cci mag rifle primers with 67.5 grains of H4350 and 190gr JLK's seated on the lands. same load with bergers but a .004 jump.

I don't really agree with the stainless rings but to each his own.  I use seekins precision rings and picatiny rail.  They are spendy but one of the best.

A light weight 300 Mag can be brutal to shoot for the amount that is needed to learn to shoot it at long range.  I used to shoot  Metalic  sihloutetts and just spending alot of time can behind a 308 can be hard.  I built a longrange 300 Win Mag in the late 70's and sold it as soon as I could and it weighed 9+#.

Mine has the recoil of a 30-30. I can shoot it all day long. If I could afford more powder.

That's what a good muzzle brake is for.

robsec's rifle weighs in at 13# and he has a muzzle break on it, it doesn't even come close to a light weight rifle. Most people consider anything under 8# all up a lightweight.  Mine weighed 9# all up sans a break and modern recoil pad. 

You don't learn to to make long range hits in the field firing 10 rounds a weekend off a leadslead.      Just the difference between a cross wind at your position and a quarterring wind at the otherside of the canyon can mean the difference between a lung shot and a gut shot.  Then you have the 1/4 mile + hike to see if you even hit it.  I've seen a whitetail take a round through the chest and keep right on walking out of sight and die just 20' into cover.  When you can put the first round in a pie plate at what ever range and conditions you decide to take a shot at go for it.  And a light weight rifle makes it just that much tuffer.  When I was younger I was pretty good at it, now I limit my shot to under 300yrds.

This is what makes you a good long range shooter.  Lots of this kind of practice.
These are my shooting buddies who I shoot with.  I am not in this video but its normal practice for us.

I agree that is how you become a long range shooter, lots of practice under all sorts of conditions.  I still think a lightweight 300 mag will beat the heck out of you trying to learn to shoot it.


I missed the post on how accurate your Tikka is, a MOA 300 Mag is a pretty nice rig.  What has been done to the rifle already, how many rounds down the tube and how many different powders and bullets have tried loading  for this rig?
