The Better Rimfire Thread

My build would be a 2500x with a Shillen Ratchet barrel in a Precision Woodcrafting stock with a Bix &Andy trigger topped with a Sightron 45x scope.

But I'm a benchrest guy so a totally different setup from what the OP is talking about.

Tesro is doing builds on CZ 457 actions and using IBI barrels. If anyone had bought one of these projects, would love to hear about it.

Accuracy you have had with rifle/barrel and ammo combo's.

I'm not familiar with the Tesro builds but the CZ 455/457 action is capable of excellent performance with a little TLC. A guy on RFC had a full benchrest style 455 built with a Benchmark barrel and he pulled off a sub 0.100" 5 shot group at 100 yards with it. The thing is, the rifles can be built to perform better than what a lot of ammo available to us is capable of delivering. That said, it's not usually as simple as slapping in a pre-fit barrel to get such a capable rifle. I'm sure more often than not, IBI pre-fit builds will satisfy the precision requirements of PRS sports. Is it getting the best out the rifle/barrel? Maybe not, something might be left on the table. To get the best out of a CZ the barrel should be custom fit to each receiver and secured with a more solid/stress free mounting than the set screws like "gluing in" the barrel with green Loctite. Their chambering is also likely not optimized for accuracy, but for function. Can't have customer complaints about trying to extract a live round but leaving the bullet stuck in the chamber, after all. The engraving necessary for best accuracy necessitates that any chambered round must be fired, trying to extract a live round not advised. Of course a balance can be struck where there is sufficient engraving to provide excellent accuracy while also allowing for live round extraction, hard to say where that fine line lies though and where a pre-fit barrel compares to it. I'm interested to see what a full custom build with an IBI barrel can do, what I've seen others post with pre-fits is encouraging.

The PRS Rimfire game puts the challenge back on the shooter for the most part, with awkward positions and time pressures. IBI does have match chamber options, but many shooters spend on the rifle and then shoot garbage ammo. Even with actual match ammunition, the inconsistency of rimfire is frustrating. I have little interest in fighting that inconsistency in Rimfire BR, where it matters a lot more.

This is an excellent observation about shooters spending on rifles and then skimping on ammo. It's always more exciting to get a high priced rifle than it is to find good ammo.

No rifle, regardless of make or barrel or chamber, will fix inconsistent ammo. Inexpensive ammos are by definition inconsistent, but even top tier ammo can disappoint.
 
I have looked at the 2500X. But a rifle was in the $5200 CAD range and I'm not ready to dole out that kind of money yet.

Haven't come across any talk about chambering and not extracting loaded rounds. Guess I'm not reading in the right places.

I am on the better ammo quest for the moment. VooDoos and Ultimatums seem to be out of stock every where. Went to Tesro's site and was looking hard at their 457 with an IBI 24" 1 in 14 twist. Was thinking I would settle on this for awhile. But still hoping for something else, I think.

Thanx guys. I am in search of better ammo. Have a brick of Eley Tenex and Lapua X-act so far on order.

I want to up my level of seriousness in target shooting and try an 1100 yard/meter shot. And definitely further than 200 yards/meters. Before people jump on me for the
Long range stuff, I am a realist and know it’s next to impossible. But I will try it someday.

Sean....one of the biggest challenges I have found is spotting. A good dry dusty area would be ideal, but don't have much of that around here. One option is floating targets on water, which can work good on calm days.
When you get your project up and running, make a trip down here to play!!

Plenty of conversations about it on RFC, use search phrase "extract live round chamber engraving" to bring some up. Any off the shelf rifle built to SAAMI specs won't have an issue with this unless there is a defect in the extraction system. It is the custom builders pushing the limits by deviating from SAAMI spec who will encounter this issue. It is two factor, the amount of bullet engraving and the holding capacity of the extractor. If the extractor has a high holding capacity, it will pull all rounds up to the point the engraving is so heavy the bullet sticks in the chamber and you pull the casing off of it. If the holding capacity is light, once a certain engraving depth is reached the extractor will slip off the rim and leave the whole live round in the chamber.

I used the 1100 yard one as there is a video of guy doing it with his 22.

I do have a rifle that is capable of 4,000 yards as it sits. But don't talk about due to the OIC thats in effect. So I do have better for long range. But it will be a learning/understanding experience. We have a 2,000 meter range in the works for my area. Done work at 2pm. So there will be lots of time to try.

What rifle are you shooting 4000 yards sounds interesting? What size target does one even use at that range?
 
If you extract a live round but find what looks like a spent case and a bunch of loose powder in the action, CHECK THE BORE for the bullet blocking it.

Have a look at Go Big Tactical. He usually has some builds as well in voodoo among others. He also sponsors a few 22lr events, and is known in the circles.

Thanx Darrel. I have a spot south of town where I think I can hit 2700 yards. Most of that is gravel road so dust splashes may work out.

Thank you for the invite.
 
So many variables . . . but being realistic about something at 1000 metres with a rimfire based on Internet Accuracy is NOT!

Conditions on any given day vary significantly from dawn to dusk as does the rifle, scope, ammunition and the shooter.

There is nothing wrong with setting realistic expectations but you have o start some place and your TESRO CZ with an IBI barrel might be reasonable.

Some of the opinions expressed are from experienced shooters but by their own admissions they range from "highly experienced competitive knowledgable", "Benchrest", "Precision Rimfire Series" to "Plinkers"!

Sitting at your computer with insufficient Credit Card funds is not hands on experience.
 
I have 3 very accurate Benchrest rimfires. I spent a lot of time and plenty of $$$$
finding the ammunition each liked best, and it has proven rewarding in the end.

Consistent 1/4" groups at 50M are possible, but even with the best ammo, you
will experience the odd round that will be out of the group. As some have already
stated, 22 rimfire ammo is the "Achilles Heel" when it comes to consistency.

I have a 100M 10 shot group here that measures .344", and many right around
1/2"so good combinations are out there.

I shoot mostly Eley Match[Black box], Tenex and RWS R50. The lot numbers I
found to work best, I laid in a fair amount of. Regards, EE.
 
Its all about having many friends and contacts to aquire ammo or loading components. Ive managed to secure a large amount of Eley benchrest semi auto. With access to cases of more albeit not the same lot number cuz I own that already haha. Secured a case of SK Long Range Match and 5 bricks of both Lapua LR |Variants. The Lapua will most likely turn into a new flavour and wrapper with no gain but Ill find out shortly and let the CGN world know.
