Thanks Darrell! I was totally surprised with this one as I was shooting off an inexpensive, plastic rest that wasn't very stable: https://www.caldwellshooting.com/rests/shooting-rests/the-pistolero/562771.html#start=1 But, I'll take it as there were a few more that weren't far behind that one. At least I've now got a good baseline! CZ Reload: 3.5g N320, Round 1 Digital Link Zero 147g JHP, OAL=1.125" Temperature: 55* Pressure: 30.07 Bullet Weight: 147.0 Power Factor Average: 132 Power Factor Low: 129 Power Factor High: 133 Number of Shots: 10 Minimum: 880 Maximum: 908 Spread: 28 Average: 899 Standard Deviation: 8 # Velocity Ft/lbs Power Factor Date 10 894 260.85 131 5/6/21 3:14 PM 9 899 263.78 132 5/6/21 3:14 PM 8 900 264.37 132 5/6/21 3:13 PM 7 905 267.31 133 5/6/21 3:13 PM 6 905 267.31 133 5/6/21 3:13 PM 5 880 252.75 129 5/6/21 3:13 PM 4 908 269.09 133 5/6/21 3:12 PM 3 896 262.02 131 5/6/21 3:12 PM 2 898 263.19 132 5/6/21 3:12 PM 1 906 267.90 133 5/6/21 3:11 PM

Darrell: I think this group and a couple others are ready for the Ransom Rest!

THANK YOU Sir!

As I'm setting up a new rig for (first time in) Production, it now appears the restrictions on holster/mag pouch placement forward of the hip bone have been removed: https://youtu.be/FxyKdBnsQIw?t=30 https://uspsa.org/announcement/738

Thanks Siberian!

Tuna: That falls in line with data another shooter has shared with me. Your COAL was just a tad longer; but only accounted for a few fps difference. THANK YOU!!!!

Thought I'd give some feedback on an older thread as I just purchased this combo and had problems with the mounting hardware........... Production rig for CZ Shadow2 consisting of Red Hill Tactical Competition holster, Boss Hanger, Shooter's Connection belt combo, and Ghost 360s pouches. Once I got everything in from Shooter's Connection, I ran into post nuts that came with the RH holster were way oversized (OD) for the Boss Y-Plate hanger. Talked to owner of RHT, and he thought, since he claims every holster maker uses the same hardware, I had a y-plate that had not had the final hole size reamed correctly. Got the Starrett digital calipers out and measured the OD of the post nuts which averaged .208" while the ID of the Y-Plate holster mounting holes measured .201". Called Ben Stoger Pro Shop and the tech said RHT was using the wrong mounting hardware and that yes, the ID of the y-plate holes was .200"-.201". Note: Both the RHT Competition holster and the Boss Hanger supplies 8-32 x 1/4" screws to mount a holster. Only RHT supplied the post nuts which were threaded 8-32 with a 1/4" long post. The issue I had was to correctly mount the RHT holster to the Boss Hanger, the post nuts must pass through the holster AND the y-plate in order to get a secure mounting of the two items. After a second call back to Shooter's Connection, a Tech by the name of Ryan, had found some 8-32" post nuts that averaged .196" - .197" OD, and he was putting me 3 of these in the first class mail to go out that day. BTW, he provided EXCELLENT CUSTOMER SERVICE throughout the whole ordeal! Couple of days later I received the post nuts from Ryan, and sure enough, they easily fit into the holes of the Y-Plate for holster mounting. One thing I think important, these post nuts had a post length of 3/16" with 8-32 threads. So I decided, since the OEM screws were only 1/4" long, to run up to Tractor Supply and pick up a 5 pack of Hillman stainless steel 8-32x3/16" machine screws. Same screw brand that Lowe's offers. A touch of blue Loctite for added measure, and this combo worked perfectly with the new post nuts! IMO, the 3/16" screws provided a bit of extra thread engagement. Hope this helps someone considering the holster/hanger combination!

Thanks big!

I too primarily shoot my reloads except for the fact that I shoot/carry factory ammo in my CCW weapon. And I have several boxes of factory ammo that I purchased when I started making the transition to 9mm. I fully realize after plunk testing a few different bullets in the S2O's barrel, that bullet profiles and weights will require different OALs! I don't prefer a shorter chamber either. Maybe it's because CZ is producing these pistols in European markets that normally use the shorter chambers.........I'm not sure, but I do know they are much shorter than my 1911/2011/Glock platforms. But I can learn to adjust for that. According to the USPSA 2020 Equipment Survey, 40% of those reportedly shooting in Production class were shooting Factory Loaded ammo! And I'm sure there are more people shooting factory ammo than those of us that prefer to reload our own. Could be why the manufacturers make pistols that will shoot all types of available 9mm ammo. FWIW, I will always respect your opinion whether I agree with it or not. Again, thanks for your feedback!

I have read that in several posts. Thanks for your feedback!

moto: I agree with your assessment as I'm trying to get information from other shooters that will get me "close" to my desired PF. And with components as hard to come by as they are right now, I definitely don't want to waste a bunch of primers, powder, and bullets getting where I want to be. Yes, I think I'll end up around 3.5g-3.7g of N320 based on feedback I've received so far. VihtaVuori has published data using the Hornady 147g XTP type bullets which IMO, the Zero 147g JHP resembles very well. The do publish with an OAL of 1.142" and I have used this length in several other platforms; just not experienced with using shorter the lengths required of the CZ. https://www.vihtavuori.com/reloading-data/handgun-reloading/?cartridge=89 At my age, I always finalize my pet loads for accuracy using a Ransom Rest if it's available. That way, if I miss in local competition, then it's MY FAULT and not the ammo! THANKS for your feedback!

tdz: I've got several boxes of various 9mm factory ammo that show OALs averaging from 1.064" to 1.110". So, I don't think loads in the 1.080" range would be that unusual.

https://forums.brianenos.com/topic/293961-trying-a-new-platform-in-production/?do=findComment&comment=3258633 I understand! And since wasting hard to come by components is not my desire, I'm trying to get solid info from others that have used my combination of bullets & powder. Thanks!

Awesome! PM coming and THANKS for sharing your data!

Darrell: I have scoured your loadsheets many times, and just not coming up with a comparable combo unless Sport Pistol meters similar to N320........ And it does appear, your heavier JHP/FMJ/CMJ bullets are working well with Sport Pistol. Unfortunately all I have to work with is N320 and the Zero 147JHP combo. Even though I'm retired, it's a major endeavor to test at length since the range for chrono work and my friends Ransom Rest are in two different, far between, locations. I do appreciate your feedback!

As this Shadow 2 is a completely new platform for me, I'm having to relearn my reloading practices to deal with the shorter OALs that are required. I've reviewed the USPSA 2020 Production Equipment Survey, and see that the top bullet weight being used (as reported) was 147g by Blue Bullets. 124g/125g was a close second. And Titegroup was #1 used powder with N320 in second. Not sure how truly representative these results are, but I do respect them. What I have a plentiful supply of is N320 along with Zero 147g JHP bullets. I've pretty much settled on using an OAL of 1.125" So, at this point, I'm wondering if any reloaders here might have some ladder results using the same or similar components that I can refer to for my first ladder of starting loads? My goal is a 133-135PF with accuracy my number one priority. Thanks for your help! HR

Thanks!

Thanks for your feedback!

davsco: Just started using discord for another purpose......care to share with a "how-to"? Thanks!

Since the 10 round and 17 round are the same price, I'll just order the 17s and keep count of my loading. 17s are much more versatile since I'm also hoping to add Carry Optics to my adventure once I'm comfortable with Production. Thanks again for your feedback!

Realizing the chambers are "short" on the CZs based on my reading, I decided to try Wobbly's "How To Determine Max OAL For A CZ Pistol." Using new Zero 147g JFPs along with once fired Winchester brass, I made up 7 dummy loads to use, following the directions outlined in the referenced article above. Results were: #1: 1.159" #2: 1.159" #3: 1.163" #4: 1.157" #5: 1.158" #6: 1.160" #7: 1.158" I threw out the highest and lowest measurements. Total for the remaining 5 was 5.794" which averages out to 1.1558". After subtracting the recommended 0.015", I've got 1.1438"; rounded up to 1.144". For many years, VihtaVuori has used an OAL of 1.142" in many of their 9mm N300 series loads; particularly with the 147g Hornady XTP. I have also used this OAL in many reloads with N320 for other platforms. Do these OAL numbers sound typical for the Shadow2 barrels? Would those experienced with reloading this particular platform recommend I use 1.142" as a safe OAL, or should I drop down to 1.140" as a better standard? I realize the RL1100 will yield some +/- variance's in my final product. Thanks everyone for your feedback. Sure helping me get started on the right track!

rowdyb: Understand! Thanks! Have seen Mec-Gar mentioned many times, so I'm thinking just order 5 or 6 of these and keep the stock mags for backup. And with Production, I'm thinking there can only be 10 rounds in a mag.........?? https://www.shootersconnectionstore.com/Mec-Gar-CZ-75-9mm-17-round-magazine-AFC--P4679.aspx Thanks Tunachaser!

Thanks EVERYONE for the excellent feedback! I feel confident that with my current inventory of "consumables", I can work up a nice shooting load. Yes, I remember well the mention of CZs usually requiring shorter OALs to function correctly. And I have "Wobbly's" Guide to Determining Max OAL bookmarked. Of course, I always download a current copy of Darrell's excellent spreadsheet. Again, thanks for all your comments!
