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.

Winchester SPP for me. I re-use mixed range brass on my SP01 Shadowline and 85 Combat. I tried CCI SPP but had a few non-ignition. Load it again for the 2nd time, it ignites. Most reloaders suggest the softer Federal SPPs and use a longer firing pin.

I shoot 135 gr epoxy coated bullets on my CZ SP01 Shadowline and CZ 85C with stock recoil springs. 3.2 gr to 3.4 gr W231 & Titegroup seems to fit my requirements. Soft recoil and accurate. I just don't have a chrono data for these loads. 125 gr seems to be snappy.

For 9mm, I will start @ 3.2 gr, moving .2 gr up to 3.5 gr or to max suggested load. I have used Bullseye before, 125 gr and 135 gr coated lead bullets and I prefer 3.2-3.4 gr for my CZ 85C and SP01 Shadowline.

Yes, I was quoting IPSC. My bad... Don't get me wrong, G34 is a good pistol. In fact, if ever I would get a polymer pistol, for a 9mm, I'll take a G17L if I can still find one or a G34. Safe shooting!

Are you sure it's Production Division? Glock 34 is not approved for Production Division. Maybe Standard Division is what you mean. "Earlier in the week I bought two Glock 34's to use in Production" GLOCK 17, 19, 20, 21, 21SF, 22, 23, 26, 27, 29, 30, 30S, 31, 32, 33, 36, 37, 38, 39. Also approved are variants with original Glock barrels which are longer than standard (e.g. 17A, 17DK), as well as variants with "Tactical", "Mariner" or similar OFM engravings on the slide, provided the barrel length does not exceed 127mm, and provided all other aspects of these variants fully comply with all other Production Division rules. Also approved are Gen4 and SF versions of approved models. Not Approved: 18, 24, 25, 28, 34, 35, 42, Pro, L and C models

Have you tried checking the headspace and your OAL? I had a similar issue with my CZ 85C. 3.6 gr Bullseye 125 LRN @ 26.5 OAL. Not a good load at all. 95% keyholed. But @ 28.2 OAL, shoots perfect. No keyholes. Try seating (no crimp yet) your bullet @ 29.0 and drop it against your barrel to check if it will seat properly. The slug should barely touch the rifling. Adjust slowly your seating length checking with the barrel until you get the right length. Then check with your magazine to make sure it fits. Then do a light crimp. Safe Shooting!

Sorry for the delayed reply. With "high primers", do you mean primers are not seated properly? Those no-fire reloads all came from the same package of 100-pcs primer tray. Never had another one after that batch. What you are describing, sounds more like high primers, rather than bad primers. I agree. An extended firing pin wouldn't make any difference with a high primer....

About half-full. I load 3.4 - 3.6 of Bullseye and it fills the case close to what you have. That Lee scale is not an easy scale to use. I would suggest to find an alternative scale for counter check. I am usingan MTM Case-gard digital scale. Inexpensive and so far, it suits my need. There are better scales in the market, and it's just a matter of making your call in what to buy.

Good job!

Double or Overcharge. A longer OAL reduces pressure and increases the chance of misfeed.
