Accurizing a rifle
I don't know why this same topic below became "locked" - but it's a great topic. Why not start it again.
Cryo-accurizing is controversial and really unproven. I'm not certain it helps at all. I've had several of my rifles "cryo-accurized," and I noticed no difference in accuracy before and after.
The major component in the accurizing process is the BARREL. You must have well manufactured, stiff (ie., relatively heavy) barrel. Some say the newer composite barrels, which are thick yet light, are also very accurate. Does anyone have any experience with these composite barrels?

Just interested in learning more stuff.
How does a gunsmith go about accurizing a rifle?
What types of things are done to the gun?
Does it hurt the blueing at all?0 -
Wow!
Well, it is not a simple thing. Different for each type, caliber, action of firearm. Gotta ask with a specific firearm and it's intended use.
Seriously, it is different from a semi-auto to a bolt-action.

The biggest factor imho is the quality of the barrel $300 on up though many of the factory offerings have a high degree of accuracy right out of the box in the heavy barrel conf. go this route and start handloading and 1/2 moa or less can be had for $1000. or less. 0 -
My advice is buy a good match-grade barrel, and one heavier than usual. Shillen, Hart, and Krieger all make great barrels. I like those that finish about 0.750 inches at the end, and 26" will give you good velocity performance. Next, buy a decent fiberglass stock, for example HS-precision or Macmillan. Next, get a good bolt action; I like Rem M700 or Win M70.
Find a very good gunsmith, especially a bench-rest rifle gunsmith; they tend to know what they're doing. Have the gunsmith put on the barrel, true up the bolt, pillar + glass bed the action, and free-float the barrel. Finally, buy a good scope and mounts - Leupold will be just fine, especially one with a B&C reticule.
Total cost = $1500, but worth the cost, since you'll have a 1/2 MOA gun. Any caliber will due, but 300 Win Mag is an inherently accurate cartridge with the killing power needed for any animal on this planet. You should also do you own reloading. You might want to consider a tight-neck chamber, if you don't mind "turning" necks. I like 83 grains Reloader 25 with a 180 grain Nosler BT (vel. ~ 3250 to 3300 fps). I know, since I've chronographed this load in a gun just like the above, and I get ? moa accuracy - awesome!0 -
It is well worth the money, knowing the rifle will put the bullet EXACTLY where you put the crosshairs is a good thing. 0 -
Great advice and all right on. I've in addition to all the info. offered have had many of mine "Cryo-Accurized". It's a computor controlled process which relieves stress in barrels. Helps greatly in preventing wrapping as it heats up. Suppose to help increase barrel life as well. All accomplished with a temp. controlled process. Good luck.

considering I don't have that type of money...
I just want to know the process of accurizing a rifle.
I have read up some on the Cryo accurized rifles, does this help at all?0 -
The last rifle I had done was a Rem. 700 30.06. I bought it new. I glassed it myself $40, had the bolt reworked $65 and the Cryo-Accurizing ran about $75. Mind you this was back in 96. Turned into a very accurate firearm and still is today.
This may be just me but I went thru the whole 9 yards breaking it in. I am a firm beleiver with high power rifles this greatly benefits the weapon and shooter in the years to come. Stay Safe0 -
Starting with a stock (factory) rifle and quality glass, 1)properly bed the action (piller or skim coat depending on action style), 2) float the barrel (remove material from the stock to allow the barrel to vibrate freely), 3) tune your handload to match that paticular rifle. Now we start spending money, 4) have the factory barrel pulled and set back 1 turn, recut the chamber to SAMMI minimum specs and recrown the muzzle (the smith should be willing to provide a chamber cast to measure/prove his work), 5) replace the factory tube with a quality (a few brands were mentioned above) barrel and have the receiver blueprinted (re-machined to be square, concentric and parallel to the firing pin).
#4 will set you back about $250 but may provide the level of accuracy you desire, #5 will cost you between $175-300 for the barrel blank, $150-250 for the fitting/chambering and the action trueing runs $150-250 (truing the action will often leave the threads oversize when they are recut so the factory barrel won't fit properly after this is done)
Some guys like a mag full of lead, I still prefer one round to the head.0 -
I had been looking at cryoing it, as I know a place that cryos a lot of stuff, not just guns. They charge $35 for the reciever and barrel. 0
