Just something to be aware of. The steel case of the 7mm BC takes up more stress than a brass case would, reducing the pressure that the action need to withstand.

With hybrid cases, the pressure that the chamber walls have to withstand is pretty much the same as a normal brass case. Just you won't get brass flow into the bolt/ejector cut-out and primer pockets won't enlarge when running higer than normal pressure. I do believe that modern actions can safely take pressure above 65kPSI, I just do not know where the limit is.

My point being, "buyer beware". Few people I know have enough engineering knowledge to run their rifles at 80kPSI safely. Obviously.45-90 has some idea.

Personally I won't try to replicate steel case performance with hybrid cases.

Running these hybrids the cases at 80k pressure shouldn't present a failure issue from all I've read. Good barrels can take that pressure, at least for awhile. My main concern is how many firings can the barrel take and keep from ringing as it seems constantly expanding the barrel beyond it normal expansion of typical ~62k max pressure the metal may not eventually spring back as much.

Honestly, I've spend 10k trying to build something that shoots as well as a Vudoo or Rimex. It's totally hit or miss just like buying a CZ off the rack. Some of them are hammers, and some suck, with the median ones shooting very well for the money. Whidden is a great shop, but I seriously doubt that the groups are out of tolerance, which is generally at the suck level no matter who you go to. I built the snazziest Summit ever, and it shoots about the same, and Volquartsen said it was within spec... Most won't make claims they can't achieve.


There is too much going on with a .22. Including the ammo. I have guns that shoot Ten X like crap, and shoot good with bullshit CCI. Try it with SK Match. I never found it to be great till I bought the Vudoo, but it was dead on from the first shot, and it's never eaten anything else.

There is a ton of Voo Doo magic and luck in .22s. It is almost impossible to get the level of precision required to overcome the shitty ammo with a production action/barrel. I've seen production guns that shot as well as a Vudoo or RimEx, but never owned one.

Imo, you're going to spend more money chasing it than bucking up. I know I have. I wish I would not have chased it and just bought it from the outset.

What can I say... I would never bet against the depths of Clinton Corruption... and the level of Commie infiltration of our republic starting in the Hippie '60's.

truth,but infiltration started in the 20s or so. the useful idiots about the same time.

50%, $250

I think there is value in consistency of the markings, so my preference is for 0.2mrad based tree reticles that are not excessively busy. The two centerfire rifles I use the most both have Gen3 XR. My rimfire bolt gun trainer that I shoot more than any other rifle I own has RG3 with EBR-7D on it, which is also a relatively unobtrusive tree reticle. I think these represent the type I like the most overall. I would prefer for both to be very slightly thicker, which is probably what I will get in the upcoming 4-24x Gen3.

Yes that's horrible. I'd expect a good barrel on something like a Vudoo/RimX to be 12-13mm. I don't think CZ actions have any particular issue unless it was horribly headspaced or something.

you noticed the Clancy look alike attack? good for you. not many people have noticed that in my experience. 1st thing i thought in truth. we are learning that it was more a CIA deal lately.

I don't believe I've read that Clancy book. However, when the covid thing started, I immediately thought of Rainbow Six from Clancy.

Spending a majority of my life watching YouTube on the side of the road then playing road pirate/hall monitor when you hit the last video in the stream doesn't sound like an appealing career. Especially since I really don't want to take a serious pay cut.

Then it sounds like it’s not that big a big deal then.

See the reality is, if it was a big deal, then you wouldn’t be using a gun forum to just come a bitch about how things are unfair. You guys are like a sub-branch of democrat degeneracy, quick to point out the things you dislike but never having a realistic solution. You want the institution torn to shreds but have no concept of what that actually would be.

You should probably take a break from the internet. You literally have no idea how the process works, so your arguments are invalid. The criminal investigation is done by an outside agency.

I keep coming back to this thread just so I can see the regulars react to the occasional violently retarded take. You boys are doing god’s work.

Had to sight in a new scope today. Still waiting on new ammo to arrive. Ran 100rds of CX. used 10rds to sight in and 10 used for tall target testing.

Best 10 shot grouping @ 100yds = .85" vertical, .30" wind
Best 20 shot grouping @ 100yds = .94" vertical, .74" wind

I did observe a cold bore shift at the 50yd which made me second guess my windage zero.

The shot groups seem to tighten up as the bore gets warmer.... I will try to source a thermal cam to record this next trip.

79 shots recorded with the XERO (1 got ejected due to cold range) the results for CX are as follows:

Min 1077.3 FPS
AVG 1091.9 FPS
Max 1110.3 FPS
ES 33.0 FPS
SD 6.2 FPS

Im curious how barrel temp impact MV and would it be worth it to set up a DAQ and thermo couple the exterior of the barrel at (X) interval.

Want to lower that ES for sure. I have not recored such a long string before. at most 30rds but typically 10 - 20.

More to come when the new ammo arrives.

33fps is about as good as you are going to get.

Over 10-20 shots you can get better but over 50+ an ES of 30-40fps isn't bad at all.

308 Win 22" 9 twist 5 R Bartlein Rem Varmint. 177 gr SMK 545 G1 BC 3045 fps, with hybrid cases.
Or single load 230 gr Atips 2601 fps ave from same 22" 308 barrel.

I love innovation as much as the next guy... Those are some HOT loads. Have you ever thought of pressure testing any of these? Have you checked for lug setback on your stock Rem 700 actions?

These loads are approaching 300 Win Mag velocities with a case that holds 48 gr of powder, versus the 300 Win Mag which holds ~82 or so. Despite the hybrid cases how do you avoid primer failures?

Don’t zoom in on the dude’s fingers. Sounds judgy as hell, but even his digits look a little off.

Blasphemy pure and simple.

I would also prefer the flush cups than someone screwing a wood screw into my stock, period. However, on the CZ 457 AT-ONE the rear sling stud is in the plastic housing that covers the adjustable comb and stock. Getting that to look professional and factory is going to be hit or miss. I haven't removed it and I kinda don't want to. Rather than deal with that I can snap one of these on and go. The front stud is getting a flush cup..
