So, I got bored and made a new video about new(to me) old CZ97B Safety model. I got some video editing practice. Digg the 97s (CZ FuddRunner) – it was a great day!
The trigger action and shape of the older one has the slight nod, but the newer model has better sights and LOK grips(upgrade). You can see typical accuracy of 230 RN Reloads at 50 yds. Not the best shooting but I love the self healing targets on the dirt berm – you get instant feedback. Round 1 is standing and Round 2 are benched and bagged.
Tested some 9mm rounds today. Testing the new shock cases and the small rifle primers in pistol (have more SRP than SPP). CFE Pistol, COAL : 1.112″
CCI Pistol Primers over 4.2 gn
CCI Pistol Primers over 4.6 gn
Winchester SRP over 4.2 gn
Winchester SRP over 4.4 gn
Had some feeding issues but I think that was mag related. I only had 10 rounds of each load and was testing each load in each of the 3 pistols. when I tried the CZ mags in the K12 caused feeding issues.
I had planned to go Turkey Hunting in the backwoods of Alabama Saturday morning. That got delayed and I ended up riding around with my old friend in the Miata with the top off. Ripping through the gears on the back country roads with new tires on the rear brings grins ear to ear. As 7 yr old kid packed in the back seat of an old blue Ford Escort with my little sister, I had always dreamed of driving a red sports car to Grandmas house – finally happened.
In addition to breaking the 870 down so it would fit in the trunk of the Miata, I also brought the 6mmARC, the Ruger 10″ 22s, and the CZs (ZomBullShadow, SP-01 Racegun, 97B mostly stock). I had planned to also do some target shooting and test some new loads in addition to turkey hunting. – all the gear packed to the gills in the Nimble Ninja (a common occurrence). I decided to stop in just after lunch at Bob Gibson’s Original BBQ house and with Swann Creek WMA range was only 15mins detour on the way back home made it an easy decision.
It was perfect weather, and I was shocked to see the range not even half as full as last time on a Saturday. Parked at the 100 yd pavilion and signed in. I had been suffering a putrid cough and loss of voice – shouldn’t be COVID as I can still smell and taste plenty, but it wasn’t fun – I braved through it and kept my distance.
First up, was the 6mmARC, confirming my “Jam the Lands” load, which worked very well to fire form about 20 cases of converted 6.5 Grendel Basic Brass. Worked great, I thought the single feeding would be an issue but it wasn’t bad at all. A friend happened to be there with his LabRadar, which brings up a question – aren’t all people with Lab Radars considered friends?
We confirmed the velocity of the of my settled load of Leverloution over 105 Bergers to be ~2550fps. I let him shoot a mag and try the rifle and got video using the ATN. Chased down all brass and it looked good. So next is loading a single case until the neck is split (4-8 times will be my guess). Then try same test using the annealer after each firing.
Next up was the 10″ Rugers. First was the Black Grand-Mamba (scoped). I sighted in at 50 yards and made some adjustments to the scope. It shot very well but then I noticed a bit of slop that I thought was coming from the push button release, but it was actually the scope mount coming loose off the receiver ( I don’t think I locktighted them). Next up was my Bond gun – the Stainless MKII 10″ barrel version with stock trigger and gold Vol Bolt.
It shot good but did have some light strikes which the MK4 finished no problem. I started shooting at small items on the 100yd berm. I was Benched and bagged so it wasn’t very difficult to get the berm targets to dance around a bit. Mostly close/about 2″ off, but also some direct hits.
I was holding the front post about 1/8″ high off the rear sight and using CCI SV factory 2nds. I did notice that hits on self healing plastic targets at this distance did not make the target move very much/at all.
Lastly was the CZ pistols, which the 97 ruled the day. I started with the ZomBullShadow, and the 90gn ammo I had just made. It did not have enough power to cycle the gun.
Switched to new Berrys 115 load and they would BARELY cycle the gun and would ONLY cycle with firm grip (great example of limp wristing).
I DID get one of the bullets to jam the action up tight. looks like the offending round did not get sized or plunked. Bagged the pistol and swiched to SP-01. Quickly realized that my dot battery was out so switched to the 97. 50 roudns of the Standard RN loads and it shot great.
9mm 90gn Hornady hollow points with nickel cases. They fired fine, shot like a 22, but didn’t have enough oomph to fully work the slide. This resulted in the case being held in by the extractor and not even hitting the Ejectorm just stayed along for the entire ride, keeping perpendicular to the slide, not picking up the next round and jamming the gun with the brass hitting the breechface just a tad off center. But, the highest load that I used I believe DID work the slide, and I remember checking the brass and it seemed OK, cratered, but not pierced – so need to finish making those (~150 bullets) at highest TESTed powder charge and do accuracy/function testing with the Ruger PC9.
The Berrys 115 gn seemed to run GREAT in the ZomBullShadow – at first. Then I got a round that hadn’t been sized at the base and it jammed the gun. I did get to shoot about 3 mags of them and they ran great. The round that locked the gun probably didn’t get sized properly/all the way(short stroking the press when getting case feed adjustements setup maybe) Either way need to plunk all rounds for the gun. The gun was bagged and dis assembled at home, looks GTG now.
Next up was the SP-01 Racegun! – This gun Would have ran great BUT, I left the Dot ON and the battery was dead. DANG!
The 97 came out and reigned supreme on that day. 4 mags shot GREAT with the stock 45 loads I had made (Berrys 230RN over Alliant Power Pistol). Called that a day and packed up to head home.
Other notes and observances: There was one 9mm round that was right on the edge of performing/running the slide. I remember limp writing one of the dev loads and the gun would jam – firm grip it would run. I went back and forth a few times to confirm. I have had a couple of light development loads exhibit this issue before, but not quite this evident. It was actually kind of cool, to be able to make the gun jam jut by having a slightly softer grip, but I don’t ever want to load action match rounds on that hair line verge of not working, better to powder up!
Cursed by my own advise that was not taken. After hours of fitting the bull shadow slide to my recent SAO build I took it to the rifle range to test at the end of the day last week. It was my secret highlight of the day, casually downplayed as “Yeah I got a couple pistols to run after we get chrono data” and similar.
Only 2 weeks earlier, I had posted somewhere, something to the effect of ” duh, that’s why you plunk your rounds”, in response to some problem with a new gun/reloads. Well, I was a little shy of the reverse capture guide rod system as I had never used one. I procrastinated and didn’t plunk rounds and figured the normal 1.125″ COAL round I had worked up using RMR 125 HPs would be fine. they ran in eveything else. Well, I got one shot and JAM and problems. I bagged it, went home, removed squib, checked COAL for this new barrel (it is tight). Worked up my loads and took some previously long ammo and seated it deeper until MAX COAL was determined for this bullet/chamber. Then I added ~0.015″ and got my new safe COAL. ITs about 1/8″ shorter than the previous round I was kind of amazed. They Shot great. After getting used to the gun on paper plate, I started doing double taps with that sweet SAO trigger at some clay pieces on the berm at 50yds.
I think my next on this bun will be reducing the load to make minor with the longer barrel, and then springing it lighter. It seemed like the stronger spring made the nose dip more that it should for follow ups. Something I’ve never played a lot with or timed just right, but I’m starting to get it.
This ZomBull Shadow SAO also fits in my shoulder holster – had to check!
As far as the 01 Racegun goes the big dot is just awesome! shot at pieces of clays on the berm, no problem. Did have a couple of minor issues with ammo feeding, but these were not plunked rounds so that should be resolved. I found this old 3D printed gripwell and put it on. the palmwells on it feel so nice!
Next up for this gun is a brass/alu magwell, remove front sight and put on old 75B slide, 8/12MOA diode, and slide racker. And tooling to work the comp up right with set screws and get back to major.
My first CZ now has new live as a Zombie build. When I first got this pistol, it was poor condition with no rear sight. I built it up in phases – here is a link to that. Later I built an SP-01 into an Open Major racegun, and swapped all the guts between the two. I decided to build a Limited gun and went with the Bull Shadow upper from CZ Custom. This build required some fitting of the slide (basically clearancing on the inside of the dust cover).
I started by dropping in all the cajun guts, the green SAO trigger going in first. I was able to do most of it by memory, getting confirmation hints on the trigger return spring and sear spring. It went fast than I had envisioned. I televised the build on Twitch, although nobody watched. Once I got the frame mods done, I turned to fitting the slide.
I just used files and sandpaper, around the sharpie and a Crayola marker. breaking the bevel on the dustcover allowed the slide to start going on, so I basically kept going. I left idiot racing stripes down the side of the slide but whatevs, going back I would have put thin tape on the slide and fit it that way. I was unsure if it was the dustcover or the slide rails. Started with the dust cover and eventually it started going back onto the frame more and more.
Testing commences today. Next ups are a magwell and S2 mag catch. With the long heavy barrel and awesome sights, this gun just points naturally.

We all have things to work on… I try to be the person to at least think those words when disposition comes along. I’m starting to feel really great about breaking bad habits. In particular for today is You Tube… So I started up Rumble and what do you know one of the first things […]
Disclaimer: do your own research and use common sense when reloading. I am not responsible for your results. Don’t try this at home or at home office either… Here are the steps that worked for me. I wouldn’t even attempt this without a great annealer. That thing is worth its weight in brass. Scope footage: […]
Executive Summary – it was windy, I learned a LOT about wind today. So windy in fact many of the more experienced shooters had issues with the wind. There was “supposed” to be an option for 1250 yds, but that was nixed due to wind. I have shot this gun 6ARC and ammo at 1k […]
Ive been looing forward to this test for a while and finally made it to the range to make it happen. The goal was to test High Velocity match ammo @200 and see if I could have a 50yd(or 100yd) zero and use BDC reticle out to 200yds. The Rig: Ruger Mk 4 lower gutted […]
