A free floating barrel is only supported at the receiver. When the cartridge fires you get a lot of oscillation, and other movements of the barrel. It is designed to do that. To prevent these movements will affect the accurancy.
So will resting a free floating barrel on a wall or a tree.

it is easy to check it is free floating as you should be able to slide a thin paper between the barrel and forend.
I checked the factory site (CZUB) but they do not say. I suspect it is.

All precision rifles are free floating

Thanks. A much better explanation than mine.

I have a 455 in .17HMR and a thumb hole stock. Like this

It's been a great rifle and I have huge confidence in it.

In .22lr it will be a wonderful tool to train with.

I'm lucky enough to own some fine rifles and I found the CZ action a bit agricultural out of the box. I remedied this by sitting it on my lap and working the action for a whole evening, cleaning occasionally and lubricating touching surfaces. At the end of that session my action was as smooth as glass.

I really think that the rule for shooting animals freehand is dont if you can possibly avoid it. I know Janne and I share a view on ethical hunting, one shot, one kill.

Practice. Accuracy of the rifle will improve a bit as you run it in. Try other ammo too.

There is a sequence for running in a new barrel. You should be cleaning in between sessions at least. I published something for my club once on this subject but I think you are beyond the first few shots?

Of course if you leave the rubber barrel band on after re-zeroing it should retain POA, albeit group size may or may not be as consistent were it free floating. Only way to know for sure is c/o empirical testing.

What I can say with certainty is rifles can shoot very well with a forward of the recoil lug pressure point as I have proved beyond doubt with my 222 Remington stutzen over the last couple of months.

To have free floated, as many Keyboard Gunsmiths recommended, a very short barrel would have been a mistake as I tested it with zero contact then with the second forward forend screw tightened for no more than positive contact with the correspondingly raised bedding channel. Difference in group size was/is eye-poping!

As you ask then Janne

Last night it was my pleasure to help one of a new members set up his new Ruger Precision Rifle for its first shots. Thank you for everybody’s patience with this. It’s to the clubs credit that part of the Xxxx ethos is the generosity of spirit we have toward those starting out.

The subject of running in a gun is a bit of a black art. I’ve been lucky enough to own a number of new guns and I think it’s perhaps worth sharing the process that I have used over the years which seems similar but not identical to other on line resources on the subject and to that suggested by our illustrious club Chairman.

The idea of running in a barrel is a subject that is often debated amongst shooters. Theoretically the barrel is polished internally during this process, removing tooling marks and other minor imperfections. I suspect this concept goes back decades to a time when we used to run in engines gently for the same engineering reasons. Tolerances in production and materials themselves may have changed but I still feel that this is a worthwhile process. It’s a precision gun you are after and what is suggested below cannot hurt. That said over cleaning a rifle can damage it but this is a process for the first 50 rounds only.

Please make sure that you thoroughly clean the guns action and barrel of all shipping and packing grease before you start. Particularly vintage rifles Cosmoline coating, used for long term storage, has been known to cause catastrophic failure if not totally purged.

So, during the first 50 shots:

Clean the barrel thoroughly after each individual shot for the first 10 shots. Leaving the barrel to cool between shots. Clean the bore with a solvent after these first 10 or after each range visit.

Shoot 3-shot groups for 5 strings. Letting the gun cool totally between strings. Patch out after each group of 3 then clean with solvent after the 5 strings or after each range visit.

Shoot 5 -5-shot groups for 5 strings. Let the gun cool between strings. Patch out after each group then clean with solvent after the 5th string or each range visit

I noticed last night that the fouling was quite pronounced in the Rugers barrel. After this process I would hope that it is noticeably less so.

Hope this is useful to some of you.

BTW the ranger bands on the forend probably aren't helping but I doubt will have much affect on barrel harmonics.

Freefloating: run a piece of paper down the whole length of the barrel between the barrel and the forend.

It's a hunter's expectation across Canada that you make the clean kill with the first shot out of a cold barrel (and that could be -20C).
A learning experience like so many other things.
Pull 20 factory bullets and compare the weights of powder charge. Fix that, too.

Of course. Once cold, the guns MUST stay outside. Kind of hide them, leave them out of sight in the vehicles.
Brought indoors with the warm humidity, the whole thing will condense water, inside the barrel(s) and out.
We bring in all the shotguns in closed cases and let them warm up before they are opened and cleaned.
That is my job after cleaning all birds. They get stripped and cleaned, all fresh lube.

If we have been caught in the rain, all gun cases are opened in the house immediately.
Cases propped open, guns towelled for the time being.

Feed the dogs first. Always. They have no choice. Have a slurp, clean all birds and think about supper.
Find stuff to eat. Have another slurp. Find a bottle of wine for supper. Cook, eat.
Strip the guns and clean/dry them.
I don't need my rifle barrels fouled with anything. Copper, lead or Italian Mixed Herbs.
Scrubbed out with Hoppe's No. 9, and dried, I am good to go again.

HA! 44 sleeps until bird seasons open again! We have about 10 weeks. I get out 15 - 20 times for first Ruffed grouse.
The much bigger Dusky grouse (aka Blue grouse) are up much higher, depends on logging road conditions.
Three species of Ptarmigan up top in the snow until mid Feb. I can't walk well enough on snow shoes any more to go after them.

Really this is for fullbore rifles Janne. Mostly these will be jackets because of the velocities involved. Won't hurt a .22 to follow a similar regime but obviously not jacketed. Don't think I've ever seen a jacketed .22LR!

"Moly" coated bullets are not something I personally use.

I hunt annually in Canada. Without any disrespect I don't find that hunters there are nearly as obsessed with this principle as we are in Europe. Filling a tag and the freezer is more the drive. Some of the bigger species also take a lot to put them down.

I've maxed out at -15 C so far but the condensation on a rifle brought in from the cold is pretty amazing. I choose mostly Stainless Synthetic rifles for this kind of abuse.

I've put in nearly 60 years of hunting in Canada. While there's no obsession about first cold shots,
you should believe that everybody wants that to happen. We all understand the chore of chasing wounded game.
We manage the temperature shifts just fine.
But for fun guns to shoot and the greatest enemy of accuracy is in your own head, .22cal is hard to beat.

Thanks again for the comments.

Janne/Hibrion I did suspect that something like that is what you were going to say. I will have to look at a scope mount for a torch.

Countryman I have shot 135 so far and cleaned it after the first 75 but not to the extent you described, I will do that before I next get it out.

I also intend the 1 shot 1 kill policy, hence using a 50mm target. Apart from an odd stray, I have been achieving this, but I will have to use some type of support to do it.

Unless i could buy a brick, that might reduce the cost a little bit, but as i only have a licence to hold 200 rounds that's out; the cost of the other calibers here may shock you.

Is that standard for new applications in Eire? I thought the UK was a tad restrictive but new applicants can get 1000+ on a new cert. Any chance of increasing that if you have good reason (target shooting, the need for different types of ammo (HV, expanding, solid, sub-sonic) teaching youngsters etc?).

You should easily get permission for 1000 rounds on the 22lr. Tell the local Garda you buy in built and many brands sell 500 boxes or 525 like federal. They should be able to issue you an updated license for free.

For a quick example of jacketed, take a look at CCI stingers.
It was already mentioned but buy a few different brands of ammo, they do not all shoot they same, you need to find the brand the rifle likes, my 455 will shoot sub inch at 60 yards of the bipod with the old 40gr Winchesters but the new 42gr Winchesters are lucky to stay under 1.5 inches inches.
I will also say if shooting foxes keep the range under 50 yards with .22subs any further and you will more than likely need a follow up shot, this is why you will not be granted 22lr for fox in the UK.

I have stingers in the cupboard. I think they are just copper washed.

Hey I'm proud of this. 50 yards. Not bad for my 13 year old girl!

Nice shooting Tex...

Slowworm/Hibrion; regarding the amount of rounds I can get, that will be my naivety in applying. The default, if an amount is not requested on the licence is 100 rounds/cartridges. I requested 200 because I didn't want to look like I was going to war or get questioned why I would want a large quantity. Looking at online prices, it might save me 10 euros overall per 500. I'll look at amending after a suitable period, but such a low request might be why I was approved very quickly :)

Snake I do realise that I need to find what round the rifle shoots best, but I'm sticking with the cheapest at the moment until I'm settled in and then I will trial other brands. I will only shoot to my capabilities, which at the moment is based on 50 yards.

My bipod arrived yesterday so I will give that a whirl tonight.
