Finally got around to picking up a CZ….
It sends them where you aim it.

Got the L3i bottom metal in and installed yesterday. Definitely a nice piece.
Turned out the original magwell from the VMTR was starting to break apart so perfect timing. Seemed like a really odd place for it to start breaking, but glad I caught it before it got too bad.
Install went smooth and I'm very happy with the quality. Also glad I won't have to worry about it breaking in the future.
Got everything back into the stock and feels solid.

I have the shorty one and 10/10 recommend it: https://grayopscnc.com/collections/arca/products/bag-stop-shorty-arca-mount
Next on my list of things to get, maybe not exactly next...the list never seems to end !
Kind of a specific question but what drag function are you guys using for your ammo in your ballistics app? I'm currently using G1 with SK standard plus but I've heard some people using G7 or the RA4. Am I overthinking?
I have pretty good DOPE for up to 100yds since that's really all that we shoot for NRL22 but I'd like to get DOPE out to 200-250. I'm on my last box of the same lot so next order will be a new lot number.
My magwell has failed twice in that specific location as well
G7 form factor is based on a boattail bullet while G1 is based on a flat base artillery shell. G1 should fit and model a 22LR better than G7. Just saying.

When I used Strelok I used RA4. I did have to true the results to get almost perfect 200 and 300 dope.
.145 G1 for Center-X for me is near perfect out to 250 yards. I was really excited to see developments with RA4 &/or whatever Litz is working on, but this is better than any G1/G7/AB curve with or without truing I've ever had for 22LR so I'm not changing until it's broken.
Before and after pic of my MTR!
I stripped all the finish off with citri strip.
Wet sanded it with 600 and used the wet slurry to fill the pores in the stock.
I used tru oil and rubbed it in with my fingers. Let it dry over night, hit it with 0000 steel wool and rubbed another coat on it.
I needed up going with 5 coats. Sanding with steel wool in between every coat.
Depends if you're just plinking or shooting matches. For matches, the longer barrel and no suppressor. For plinking, suppressors are fun as hell.
I target shoot at home . I have 1000 yard range and I will want to stretch the rimfire out a little and being heavier doesn’t bother me . I just didn’t know if barrel length changed velocity like it does with the center fire stuff
A heavier barrel will definitely help since you're gonna be shooting that kind of distance. You could always go for the shorter threaded barrel and get a different barrel later. It's only two grub screws to replace the barrel.
Oh easy barrel change I like that . Thanks for the input . So the longer barrels only added benefit is the weight? Like I said I have had 22s my whole life but never a nice one and I have never paid attention to the nuances of rimfire
With 22 LR barrel lenghts over 18 inches or so actually slow the bullet down, you will loose muzzle velocity. But it have shown for many manufacturers and gun smiths that it's beneficial for accuracy, hence why many precision 22's are around 20 - 22 inches.
Lots more to it, but that's what I've learned reading and listening to the 'big names' in the rimfire world.
Yeah, I wish they had an option in the middle somewhere
If you're going to run the suppressor, then get the shorter barrel.
And also buy the new barrel that L3i just introduced for when you're shooting without the can.

All this shooting without a can talk is blasphemy
I don’t know .. I like to drink beer and ring steel some people don’t like that
Do anyone know specifics about CZ's 'accuracy guarantee' on the MTR?
They claim
'15 mm groups at a distance of 50 m'
But I haven't managed to find any info about what ammunition they use, or if there's any form of return policy if your specific rifle doesn't manage that standard...

Pulled my 457 out of the safe after several years of squatting. Getting it ready for my range to start Extreme Long Range Rimfire-300 to 500 yards. Made a few mods to it. MDT 50 moa base, MDT bipod, Anarchy Dragon Scale bolt knob, JARD trigger set at 3.5 ozs, and DiscoverOPT 5-25 MRAD FFP scope. Tested at 50 yards with SK Rifle Match. 5 shot group. We shall see if this old dog will hunt soon.

From being around a few guys at matches with 16.5" bbls, it's obvious that they're quite a bit louder - even with std vel match ammo - than guys with 20"-24" bbls. If yours shoots at least as accurately suppressed as it does w/o the can - and the accuracy is good enough to suit your needs - then I probably wouldn't mess around with a tuner. None of my rifles - including Vudoos & CZ457s with Shilens - shoot quite as good suppressed as they do w/o a suppressor. I've got Pro-X & Harrells tuners on the two Vudoo repeaters that I shoot in matches, and they both have Kriegers that I finished at 21" & 23".
it really just depends on your specific rifle what ammo it will like. I would start with SK Rifle Match due to performance to cost ratio. Mine shoots it lights out to 100, but anything beyond that I’m using other options in matches.Do anyone know specifics about CZ's 'accuracy guarantee' on the MTR?

What would be a better ammo pick for longer range?
If it shoots tight groups at 100, it should be tight further out...
The stock makes an otherwise excellent rifle feel a bit cheap. I have a tacsol aeris on it. It shoots lights out with cci standard velocity. All you hear is the bullet hitting the target. I chose the 24 inch barrel to keep it close in length to my centerfire prs rig.
Not true. I’ve seen plenty of ammo shoot great at 100 and fall apart at 200.
For matches I’m running Lapua Long Range or Eley Match. Practicing with SKRM or SKLR.
RWS R50 has the tightest groups at all distances with my rifle, but it’s been impossible to find all year.
Geez, I wonder what ups just dropped off?

General wisdom is try a little of everything. 22lr in general is barrel dependent for ammo pickyness.
Has anyone else experienced issues running the L3I magazines with their Billet magwell? Both mags are extremely difficult to seat when compared to OEM mags in the same magwell. Im hoping they just need some wear/break in…
The price of 22 ammo generally corresponds with its consistency. When 20+ shot groups are used, or are electronically overlaid, the truth comes out. Lot testing is sound, but very few shooters have the skill, equipment, and mental precision to benefit from it, let alone wind free conditions. Lots of internet Rimfire ammo gospel presentations are not statistically sound.
I seen a video on his page about adjusting the magwell. Go on his YouTube page and check it out
I installed the billet magwell in my MTR, and the L3I mags fit great. The factory polymer mags are stiff. I did not need to do any adjustments.
Only slightly. The barrel length will effect SD/ES numbers though.. The ARA guys all favor the 24" version for that reason. Benchrest guys favor longer barrels for that reason as well. Lower numbers will help at longer ranges to keep your groups tighter. My 24" At-One shoots as well as my MTR at longer distances.

Picked up a 16.5” MTR, looking for a chassis that’s got adjustable cheek height/lop so the lady can shoot it, and one that would balance the gun for barricade shooting - any recommendations?
It's going to take a lot of weights to make a 16.5 barrel balance for positional shooting off obstacles and barricades.
That being said, I think you're two best options would be the Grey Birch LA chassis or the MDT ACC gen 2. I think those two have the best forend to buttstock weight ratio.
Honestly though, you'll probably end up spending so much money on weights to balance it out, you could probably just buy a heavier barrel. It takes an extra 3-4 lbs in the forend to balance out the 457 with an average weight scope.
