bugsy

Got one from a commercial reloader. Shoots fine on my SP01 Shadowline. Empty case was fine. Avoid it if you can. Might not be a problem for some pistols. Others might pose a dangerous consequence due to a short casings on a deeper chamber.

Try 3.4 gr Bullseye.

I shoot a CZ SP01 Shadowline and an 85 Combat 9mm. When I started developing loads, I had the same issue. The culprit: OAL. Load your desired amount of powder and adjust your OAL to the maximum your magazine and chamber can handle. Hope this helps. Safe shooting!

Titegroup W231/HP38 Bullseye

With an Auto-index Turret and a Progressive Press, you can do a double stroke by not pulling the lever from top of the stroke to the bottom. Loaded casing will not move to the next die. Powder like Bullseye, 231, TG used on a 9mm @ 3.2 gr to 3.6 gr will fill the case almost completely that you will have to force the slug to seat (also a dangerous situation). There is no substitute in paying a very close attention while reloading. If you feel that you are being distracted, stop reloading. If you feel your equipment is malfunctioning, stop reloading and check your equipment. Replace only with manufacturers components and stay safe. Mods from an untrained DIYs if not done correctly is a disaster about to happen. Stay Safe!

Get a Progressive Press with Powder check. An Auto-index Turret press will also do the trick. Powder Check will not guarantee an over-charge but will only indicate a double charge or a no-charge at all. Always do a FULL STROKE of the lever to advance to the next operation. When you visually see a powder-drop without hitting the bottom of the stroke, there is a chance of under charge. Always complete a FULL STROKE before advancing to the next operation. A regular visual confirmation and weighing of the dispensed powder will minimize unsafe situations. And as a rule of reloading, FOCUS. Stop reloading at the first sign of any distraction. Safe Shooting

I also noticed difference in the diameter of the casing. After re-sizing, I notice Speer being the most consistent, WIN the least consistent, FC, RP average. Grouping from Speer seems to be the tightest. I believe this also depends on the barrel. This result was based on CZ 75 SP01 Shadowline and CZ 85 Combat.

Same problem here with CZ 85 Combat with original length firing pin. Needs a 2nd strike to ignite. This problem was solved using an extended firing pin. As mentioned above, Federal and Winchester primers seems to be a better choice for a reliable ignition.

Production Div. requires a 125 PF. Since you are using an SP01 Tactical, unless this is modified into a SA, I am assuming that you are in this division. There is not much benefit in doing a higher PF in Production Division. 125 to 130 should be enough unless you want more bang and significant recoil. With the Lee Autodisk, you will be limited to the opening for your charge. To fine-tune this, grab a piece of a big plastic straw similar to the ones used in Bubble Tea/Smoothie. Cut squarely to the thickness of the Lee Autodisk. Open one side cutting from top to bottom. Roll and insert into the Lee Autodisk Opening. You can make some adjustments by making it thicker or thinner and powder drop will get you into fractional grain. Works for me with TG, W231 and Bullseye. I generally use 3.2 to 3.4 gr TG against a 135 gr Epoxy Coated LRN. Soft recoil on both my SP01 Shadowline and 85 Combat. Safe Shooting!

I've been using TG for a CZ 85C and 75 SP01 Shadowline for a while. Though Bayou bullets is not available here north of the border, I got good results in both lubed 135 gr LRN and 135 gr epoxy coated LRN. 3.2 to 3.6 gr allows consistent cycling for both pistols. Same load has been tried on a similar Stock II with no problem. I have no chrono so I cannot give you the PF rating. I am hoping that this will make it to at least 125 PF. I've seen posting from other forums that says 128-130 PF for a 3.6 gr TG on 125 gr LRN. Hopefully, I am on track to hit the minimum 125 PF using 135 gr bullet @ 3.2 - 3.6 gr TG

3.2 to 3.4 gr Titegroup 135 gr epoxy coated bullet cycles perfectly with my CZ 75S P01 Shadowline and CZ 85 Combat. Sorry, no chrono data. Grouping is as tight as 2-3" freehand @ 20 m and as close as 1" using a pistol bench rest. Safe Shooting!

WIN seems to be a commonly available brass. I reuse my brass and I prefer R-P (1) Speer (2) WIN(3) and whatever I can get hold of. I soak used casings in detergent with alcohol or a mild solvent, rinse, dry and tumble/polish. Put a light chamfer against anything with tight primer pocket and you are good to go until you see some cracked casings, then time to throw them out.

I load 135 LRN Epoxy Coated @ 1.10" (28 mm); W231, TG, Win SPP for CZ 85C and SP01 Shadowline. Soft recoil and on a good shooting day can get 2-3" group @ 20m.

I'll start with 5 rds of 3.0 gr TG, increasing by 0.2 gr up to 3.6 gr, You have to figure out the OAL with your barrel. Mine is around 28 mm for a CZ 85C/75 SP01 Shadowline. Same load using W231 and Bullseye (extremely smoky)

I use 3.2 gr Titegroup with 135 gr Epoxy Coated Bullets, Win SPP. Start with 3.0 gr working your way up @ 0.2 gr increments to the maximum listed under HOGDON reloading data. My estimate, you should be between 3.0 to 3.4 gr @ a minimum 125 PF.
