HOGRIDER

A while back, I ordered some samples of Blue Bullet's 147g coated as they were the #1 reloaded bullet in the 2020 USPSA Equipment Survey! After speaking to a rep there, he sent their new RN profile along with their regular flat point. To give me a .015" cushion in OAL for the S2 Orange, I ended up with max 1.110" on the new round point and 1.120" on the standard flat nose. Have not worked on any test ladders at this point. Pic for reference, and of course YMMV...........

highxj: Lot of info regarding the "alpha dropper":

Sig: That's pretty much my understanding also. Since the original MBF was sold to DAA, the info I had was the MBF/DAA units they were selling separately and included with the MBF were manufactured in Europe to DAA material specs plus a plating of some type. And that Alex/PE was the only USA manufacturer making them to the original specs........ Still would like to hear some measurements of the u/l steps of those three......... Thanks!

Cuz: Glad I could help! When I started down this 9mm "rabbit hole", it was shooting GSSF with Gen 3/4 Glock G17 and G34s. And as you know, they had very long chambers that were basically restricted by mag length. Then I switched to the 1911/2011 platform and for the most part, it was not uncommon to load ~1.140-1.150 and still have plenty of cushion for oal variations. Then, after acquiring the CZ and experiencing some OALs that just seemed way too short, I too decided to pull out some manuals; and also measure the OALs of several self defense and match, factory loads I had acquired over the years. And like you, I was shocked to find that 1.10" plus some a bit longer and some a bit shorter was just not that unusual! Since I primarily use VihtaVuori powders, a quick scan of their current 9mm reload data shows tested OALs from 1.035" to 1.157"! And this is shared in many of my other reloading manuals! So, I feel confident your 1.09" OAL for the PCC is well within accepted specifications! Load on!

Mark: Great representation of the subtle differences in these three units. I would be very interested in hearing the specific measurements of the lower and upper "steps" of all three if possible. And if any have a polished, plated, or bare metal finish? Thanks!

After purchasing my first CZ, an S2 Orange, I quickly had to adapt from loading 9mm at 1.142"-1.150" down to MUCH Shorter OALs! Did a lot of "plunk" testing between 135g and 147g coated lead along with 125g and 147g JHPs. From the examples I had (Bayou, Acme, Blue, and Zero) I found that the 147g Coated flat points and the 147g JHPs allowed me a longer OAL vs the smaller weights. IMO, whatever bullet weight and profile you may be was considering, I would definitely call the manufacturer and ask them how their particular profiles work in CZ (short) chambers! Attached is a pic for example: My current match load, the Zero 147g JHP on the left, easily clears at 1.125". And would go out to 1.145" if needed. The middle Zero 125 JHP Conical AND the right side Zero 125 JHP both have to be loaded max 1.080" to give me my desired .015" clearance. So, particular ogive profiles definitely play a huge part in chambering successfully in our CZs! Good luck!

As I stated before, Alex/PE is making his powder funnels to the original prints and specifications of the original MBF design! They are excellent quality!

I also use the Redding Pro Micrometer Seating and Crimp dies. They definitely help create excellent bullet alignment in the case. However, IMO, that bullet has to have the proper "seat" for bullet placement prior to the seating die. That's where the MBF type powder funnel comes in as sold by DAA, Uniquetek, and Photo Escape! https://www.photoescapeinc.com/products/powder-funnel.html https://www.uniquetek.com/product/T1582 Related post for examples:

I'm thinking your looking for a good Self Defense load vs low Standard Deviation from your reloads........... After using VV powders for a LONG TIME, I totally agree with ltdmstr in that I've never expected to duplicate VV's published loads as they are from test barrels in a controlled environment. I do think that the reload your after is possible with the right combination of bullet/VV powder/same headstamp brass, etc. Your rifle reloading techniques should agree with that. IMO, look at the VV reloading data to see what similar results you can find for your desired bullet/powder combo. Then as always, load up a ladder and run across the chrono. There should be others here that reload their own SD ammo that can offer more details. Good luck! PS: be sure and grab a copy of Darrell's load data! Has a wealth of information!

Got a couple of these in, and they are identical to the stock slide stop that's in my S2 Orange. https://czcustom.com/cz-p01-slide-stop.html Packaging references numbers 0421-0081-41ND and 0420008004.

Welcome to the Forum! The "search" function is your friend! Example:

Glad to help!

Mark: Thanks for bringing this to our attention! IMO, it just keeps getting better and better for us reloaders!

SubMOA Pro for the Apple devices: https://apps.apple.com/us/app/submoa-pro/id1079101633 IIRC, it's called Range Buddy for Android. A little steep learning curve, but the online help makes it much easier!

Absolutely NOT! But I do know that if I miss it's me and not my ammo! Per the OP's request, I did share my recipe and RR test target to back it up.

I got a notice that these were in stock: https://czcustom.com/cz-p01-slide-stop.html Since this SKU# is not one that I'm familiar with, I sent Angus Hobdell a PM to see if this was the SAME part that I had been waiting for which was an exact replacement for my Shadow 2 Orange. His reply was this is the correct part. So I ordered a couple of them. I hope they are indeed the same part that comes stock on the S2O.

I'll also chime in to share that one of the things that makes it easy for me to "brag" about the Redding dies is the consistency/repeatability of the Pro Micrometer dies! IE, if I change bullet type/size/profile, and I need to shorten/lengthen the OAL say .005", I can refer to my notes and move the seating die micrometer .005" and it will be very, very close to my desired setting! As Mark mentioned, much easier to reach up and adjust the micrometer vs "trying" to adjust reset the 1" die nut! IMO, they are very much worth the additional costs!

Rocketman: I don't have a CZA01.......yet......, however I do have a Shadow 2 Orange; and I have to say it is one of the most accurate pistols (out of the box) that I have ever owned! And I feel the Orange and A01 probably share a similar level of accuracy and performance. This is my current favorite out of the Orange: Hope this helps!

boatdoc173: As Boom stated, definitely remove the spring from the Seating die for a bit more consistent OAL. If you notice any "sticking" from the crimp die, the insert can be easily polished/smoothed up to all but eliminate that. I followed the written instructions that come with the dies, and they have operated flawlessly! My OAL and Crimp consistency has been EXCELLENT! Good luck!

ddc: Thanks for the detailed feedback! I think I'll just pay attention to everyone's input and see how the new Dillon is accepted with Forum members here offering feedback. Have to honestly say I've never paid a lot of attention to the Ammobot unit; but have always thought the M7 "appeared" to be very smooth during the YouTube videos I've seen. And I like seeing the M7's various sensors that are available. I think our options are going to be plentiful with all the "players" entering the market. Thanks again!

I have to say of the Eemann Tech items I have ordered from DOT40, they have been the exact parts that I ordered. Most recently I ordered an Ultimate Trigger for the S2O, and later that evening, I decided I really wanted the gold/brass unit. Sent an email to sales: and very shortly after, I received an email from Pablo stating he would be glad to do the swap to the brass unit. Also gave me the July 4th sale price since I missed the cutoff by a day. So, do your homework and order the exact parts you want/need. I have found DOT40's order fulfillment very timely as long as it's an item that's IN STOCK. Any doubts? Call! My biggest complaint, and it's not any fault of DOT40, is if you use USPS for your shipping carrier, the service from the Miami area is VERY SLOW!!!!!! Use another carrier if you need something quickly!!!!

Thanks George!

Awesome view! Now I remember your setup from previous posts! Great job!

OEM if you don't mind the weak value of the dollar and LONG shipping times............ https://www.ericgrauffelonlineshop.com/en/cz-shadow-2-orange/964-cz-slide-stop-shadow-2-.html TBH, I would have no problems keeping the Eemann Tech unit as a spare when needed.
