OP here,
I wanted to follow up incase anyone was interested, or somebody finds this thread by googling.
I decided to have my barrel throated/reamed by patriot defense and I am pleased with the results. I had received a 500 bullet certificate for the precision bullets so I felt that the expense of the service was justified. I have not noticed diminished accuracy or any other issues with my barrel.
Ultimately I decided not to use precision bullets. Precision specially advises against titegroup usage and I have a surplus of titegroup. I opted for Acme 147's instead, despite them being slightly more expensive.

I also experienced this problem twice [on one stage during a match] with my Mac-gar AFC mags with shock bottle base pads. I had to grab the slide and sling-shot it as the slide stop wouldn't budge.
The stage was some kind of steel 3-gun stage repurposed for USPSA and my stage plans dictated I shoot the gun dry and then move. Otherwise I would have to go 1-for-1 on the center position.

So I do plan on helping out with this certification, but the main reason I am taking it is because my local private range will let you rent private bays if you are an RO (or higher certification).
Turns out there is a $50 class this weekend (that apparently is a rare occasion). While I do shoot USPSA I am fairly new and really only know the basics, I shoot production and know what I can and cannot do, I just go out and have fun.
My question is... do I need to literally know the whole rule book (all divisions and different scenarios) and be familiar with everything? There's no real info on the class other than where and when.
Where is the class? In Florida? I may be interested if it's not full...

Very helpful picture. It shows too things.
The first is that with the Bayou, the 'shoulder' is closer to the base of the bullet than on the Precision, meaning the ogive starts sloping away from the bullet's maximum diameter closer to the base than on the Precision. You can tell just from the picture that between those two bullets at their max OAL, the Precision will have more of its ass stuck down into the case.
The second thing is that you can see a significant bevel on the base of the Bayou. This means you can get the base of the Bayou a little deeper into the case without engaging case walls where they start to thicken around .300. Again, somewhere in that neighborhood, the interior diameter of the case starts to shrink, and it's not ideal to have the bullet shank get below that point.If you look at the pic below of a bisected 9mm case, you can see what I referred to as the "mechanical limit" or "hard deck" adjacent to the arrows. From the case mouth down to the arrows, the case wall thickness is the same. Below the arrows, the case walls start to get thicker, and the case interior narrows. You do not want the base of the bullet to get below that point. As you can easily picture, the bevel on the Bayou would allow the true base to get a little below that point without issue, but once the full diameter of the bullet -- the shank -- gets below that point, it will start to get squeezed by the case walls, and one of two things must happen -- either the bullet base gets swaged to a smaller diameter, or the case walls will get pushed out. You are better off if neither of these things happens, so I would suggest you keep the bullet base above that level, which is .300 from the case mouth, except with a beveled base, where you can go a little deeper without problem.
NOW, as to your bullet in particular. You said you don't get it to plunk and spin freely until 1.08. Your bullet is .660 in length. So .75 + .66 - 1.08 = .330. Your seating depth at that OAL with that bullet will be .330. AND that Precision bullet has a flat base, meaning you don't get the leeway of a bevel. My guess is that that bullet is NOT going to work well in your CZ. If you want to check it, load one of them to 1.12 and pull the bullet. Measure the base. That will give you a baseline for base diameter above the mechanical limit. Then load another one of them to 1.08, pull that bullet, and measure the base. Do the bullet bases measure the same? Has the one that was loaded to 1.08 had it's based swaged down a little to a smaller diameter? If that's the case, accuracy will suffer. This could be anything from the occasional frustrating flyer that there's no explanation for, to consistently bad accuracy, to outright tumbling. NOW, if there's no effect to the bullet base, and the case walls aren't getting bowed out in a way that affects feeding, then load away and have fun. But if loading to 1.08 swages the base at all, you'd be better off using them in another pistol and looking elsewhere for a good bullet for the CZ.
Enlightening
Thank you for another in-depth explanation.

I ultimately decided to send my barrel to patriot defense. The 500 precision bullets were from a certificate I was given, so I feel as though I am coming out ahead.

Will, I just found an old post from Smitty79 (but on another forum) saying that he couldn't get the Precision 147 to work in his unmodified CZ, and Smitty knows what he's doing. It's DEFINITELY still worth your going through the process, but it may be that these are a no-go, unless you want to ream. I'd recommend you shoot them in another pistol, and buy more appropriate bullets for your CZ.
ALSO, you mentioned you are new to CZ. In terms of recoil impulse, I personally prefer 124/125gr or 135gr bullets for my heavier, all-metal pistols. And I prefer 135gr or 145/147gr bullets for my lighter polymer pistols. If you learned to like heavier bullets in a lighter polymer pistol, like a Glock or an M&P or any of the other polymers, you might want to try a 124/125gr in your CZ. The extra weight washes out the snappier recoil impulse. You won't have insurmountable OAL concerns. They'll shoot flatter. And recoil management comes from your grip, shoulders, legs, and feet, not from you bullet choice.
Just a thought.
And don't forget to post that bullet length. Still curious.
The precision bullet length is .66. For those curious, I will attach a comparison of a bayou 147 fp to at the 147 precision bullet.
I ordered 250 135gr cone shaped projectiles from Blue Bullets and 1k 115gr fmj from my friend(I'm not crazy about 115gr, but I'm getting them for $.043/per projectile). I will compare them to my 147gr loads once I dial in the 115 & 135 to ~130pf. Then I'll shoot them in a 4 stage Tuesday mini match at my club.

Thanks everyone for your helpful responses everyone.
IDescribe, I especially appreciate your detailed responses. I will post again tonight with the bullet's length and a proper follow up post.

I received 500 of these(http://www.precisionbullets.com/store.html) in 147gr. I loaded some to 1.135-1.147, they passed my Lyman gauge but got stuck in the rifling of my barrel. I reduced the oal length to the point at which they would drop and spin in the barrel. This turned out to be around 1.08.
I believe this is due to the profile of the bullet, specifically the width near the case mouth extending towards the nose. My bayou and xtreme bullets loads both work fine in this barrel.
I'm very new to CZ so any thoughts or suggestions would be greatly appreciated.
Thanks.

Slide / mag , 220/221 , whatever it takes.
I never limit myself to correct use of the language.
Other thing, the USPSA president was in the squad ahead of mine today, it is tacky to bother people with work stuff when they are trying to have fun on a weekend but there was some dead time while we were waiting on their squad to finish a stage & he wasn't busy so I asked him about the S2's.
The gun itself was looked at more than a year ago and its construction is aok approved for production.
They are waiting for CZ USA to get to 2000, they are in communication with CZ USA, they will be delighted to respond as soon as the 2000 number is reached and they have heard the question frequently from many different sources.
That's good to hear. Hopefully the remaining batches will be delivered in the coming weeks.

My first USPSA match will most likely be at volusia gun and hunt club in new symrna since it's the closest location. I would like to branch out and shoot in Orlando also since I hear they have a good complex there as well. How about yourself?
Volusia is about 2 hours south-east of me. Never been, as I'm not really willing to drive more than 40min for a club match.
I typically shoot at ShootGTR's Tuesday night matches. Although I haven't shot in about 1.5 months.

Hello,
long time lurker who finally decided to join the forum. I started shooting about 1.5 years ago and have been shooting more and more local matches. I'm from the central Florida area. Was shooting a gen4 G19 and recently acquired an M&p9. Look forward to shooting my first USPSA match in the future as I mainly shoot steel and idpa. Glad to meet you all and hope to run into local guys!
Where are you shooting at? Goodluck at your first USPSA match!

I wish they'd make a 9 the size of the 43 or shield

I like to stick to Stoeger's books. I find if I start looking at too much content from different guys I lose focus.
Read practical pistol, then start working out of the dry fire book and skills and drills. You'll need a shot timer too.

Apparently Troy goes back and forth on how the protocol works. Back in 2013 he said it was units worldwide in response to a certain FN gun getting on the list when only one guy had one.
Wasn't the stock II added to the list in 2013(I could be wrong here)? I'm pretty sure there was not 2000 of them in the US at the time. I'm guessing Troy's interpretation of 2000 units was clearly different in 2013 than now.

So I have been listening to Practical Pistol, That Shooting Show, Triangle Tactical, and Shannon Smith. What other ones are out there that people like. Looking at ones that cover USPSA.
Thanks! I listen to practical pistol, but I've been looking for others.
Can anyone vouch for the "power factor show"?

Be sure to give us a look at the Port Malabar Rifle and Pistol Club in Palm Bay. IDPA, USPSA, Steel Challenge and more.
Port Malabar is an excellent club. I was a member there when I first came to Florida.

Black and gray have polycoat OVER the nitride. All guns are nitride then they inspect. Those with imperfections from machining become black and gray versions bc the polycoat covers those imperfections. It's applied over the nitride.

What's the advantage of having only nitride, compared to nitride and polycoat?

Called CZ USA and was very firmly told all the S2s have a nitride finish. Polys just get the polycoat over nitride and come with different mags. Slavex mentioned this in another thread as well.
I thought that all the slides are nitrated, whereas the blue version has a nitrated frame and slide while the black and urban grey do not?

Good luck! Hope it's the nitride version. even if it's just the black poly, it's still a great deal!! And honestly the MecGar AFC are proven, no real need for nickel mags.
There is a need. The need is to have shiny magazines that look cool and may or may not have an immeasurably small advantage lol

That's crazy.
Did glock pay the shipping or did you? And don't tell them reloads were shot though it!
-
Shoot a division like production in which you can be competitive shooting your stock 34. Reloading is not a big deal.

The CED 8000 has a headphone jack. That's what I use for dry fire when I don't want to piss off my wife in the next room. But it's not worth a damn for live fire when you're timing yourself. I use a Pocket Pro 2 for live fire.
Thanks for the heads up on the 8000. I like the idea of being able to use a headset and it looks like a gameboy sp which is a plus I guess lol
Thank you for another in-depth explanation.
