Kind of confusing, if you are using a crimp die on your 223 check and make sure it is not bumping the shoulder. The difference between presses, even though small, can lead to issues. Also, explore the "floating" die tool heads. Some precision rifle people swear by them (I use them for rifle rounds).

If TG is what you can get, then use it. Here's my list of preferred powders in order of preference for 9 minor coated bullets. 1. Sport Pistol 2. N320 3. Clean Shot. 4. W244 5. TG They are all high-density powders, at 130+ PF feel the same and feed consistently from Dillon Powder measure. As far as smoke goes, different manufacturer's coatings smoke more than others. Blues seem to be the least while ACME was the worst. I have also noticed the more crimp one uses seems to contribute to more smoke. I believe it has something to do with the coating abrading a little bit more as the bullet heads down the barrel. Therefore, it burns sooner. What I did find is TG seems to cause carbon to stick to my gun and make it harder to clean off. Maybe the extra heat, or something else in its formula. TG does leave a bigger stain on the powder measure tube the others. Again, if TG was all I could get then I would use it.

Perfect. I have the Redding Comp Seating die for 3 rifles and they are the best. However, I tried it years ago for pistol and it actually wasn't worth it. The amount of adjustment to get the same results as a basic Dillon, Hornady or Lee seating dies isn't worth the price to me.

This is the slide with the milled in front sight? If so the only option you have is to mill a dove tail grove in the front and install a sight for it. I know J & L did this in the past, not sure if they still do. Call them. https://www.jandlgunsmithing.com

Interesting theory. My experience is a 115 at same minor PF as my 147 has substantially more recoil, rise and dip than the 147s. As far as accuracy goes, no real difference in Shadow 2, but my stock Glock 19 barrel likes at least 1000 fps to achieve good accuracy. And this is the joy of reloading.

I assume you are using factory 147s because the key to soft shooting isn't only the weight it's the powder load. With 147s one can make minor PF with less bang because of the greater mass of the bullet. Yes greater mass should have more recoil, but the lower powder loads are what compensates for the extra mass. Accuracy is a function of many things, one of which is velocity and stabilization of the bullet. A 115 at a higher velocity maybe more accurate than a slower heavier bullet in your gun. This is also why rifle shooters, depending on the bullet weight, have different preferred rifling twist rates.

Yes the solid ejector didn’t help me. The recommendation to clean and polish the plate is probably the fix.

It has been my experience the new plate from Dillon are machined to a tighter tolerance. You are going to have to experiment with the ejector spring to get the round to start out a bit sooner. The closer the spring is to the plate the better it works.

Over the past few years at the Nationals 147 had a slightly higher use than 124s. It's all about preference, one weight over the other won't make a shooter great. If you reload, shoot both and find out what you personally like in your gun. Do it in matches (under pressure) and practice.

The poster is correct about the mass of the slide, it is basically the same as 9mm. However, 10mm should have a greater acceleration of the slide and therefore more recoil, we all feel it when shooting. Just compare the difference between 308 and 6.5 CM, same gun, similar sized cartridge, but big difference in recoil. A full power 10MM does slam the slide harder than 9. You might try using the Sprinco or DPM recoil system. It does reduce/cushion the slide as it travels back. The forward movement will be about the same. The frame mounted optic mount is a better solution but does limit holster options. The other "fix" is the JB Weld solution. JB Weld is used a lot for seating optic mounts on rifles. Pretty simple, thoroughly clean mounting surface (free of oil and dirt) and put a thin layer down then mount the optic. The big issue is removing it. You will need to heat slide to remove the optic. No matter what you do full power 10mm is harder on your dot than 9mm.

Other than the thickness of the cerakote finish and adding shims to the trigger and hammer for side to side movement, which is already minimal, there isn’t really anything to “tighten.” The gun can be polished internally and have the sear and hammer hooks cleaned up a bit (not recommended on stock parts because, my understanding is, they are surface hardened). The rule for minor deburring probably does not include polishing the internal parts. Depending on who interprets the rule adding shims would not be allowed.

My experience is they didn't respond very fast to an online request, but a call got immediate attention. Hope your experience is different.

Depends on the trim length. Most here assume this is an AR style platform. If it's a precision bolt gun, OAL can be made to fit jump from lands.

SAAMI Specs for OAL are 2.125" - 2.26" 223 Remington MAP (CUP) – 52,000 MAP (PSI) – 55,000 Headspace – Shoulder @ .330 Headspace Dim – 1.4636 to 1.4736 Max Case Length – 1.760 Trim to Length – 1.730 COAL – 2.125 to 2.260 Head Diameter – .378 Bullet Diameter – .2245 to .2215 However, pressures are based on how you loaded it.

Go back and read again what I wrote, except for changing the trigger there is no advantage to converting to SAO. The SA physically works the same. That is not an “over generalization.” Even though you removed the post you did insult me. If you have anymore to say keep it off the thread and PM me directly.

The Grams follower is thinner than stock so it allows and extra round. Do a search and you will find there are better followers available than the Grams. Grams have a tendency to flip and jam where the base plate meets the tube. The fix is a simple bending of the spring.

1. 223/5.56 can have very tight primer pockets plus the crimp ring can catch on the primer even after swaging. This can cause the primer to no align well with the pocket. Swaging has to round out the pocket edges. 2. Do you have a 45 brass on top of your follower rod? The blue tip only needs to be replaced when it becomes deformed and starts allowing more than one primer to drop out at once. Clean you primer magazine tube. Finally the primer shuttle is really rough from the factory. Polish the top with 600 grip wet and dry or finer. This allows the shuttle to slide across the next primer and not cause it to tip. This may help with your crushed primers from not being flat in the shuttle.

Yep, the Syntech 150 coated has been a problem over the last year or so. I've seen multiple shooters, not just CZs, having issues with them being too long and even tumbling. Just bad QC I guess.

147 RN yes that's the length. Loaded 10k of them and then switch to the FP years ago because of the hassles. I use 147 FP like this: Every coated manufacturer I know has the same or close to the same profile (I've purchased this profile from at least 6 different MFs). These load for stock CZ Shadow 2 (and everything else) at 1.11+ and I can't remember the last time I had a bulging failure with them. The Everglades FP 147 V2 can be loaded to 1.14 but they are about 3 cents more. I really like them, easy to load and clean, but don't think they are worth the extra price. Bought 4K on sale last year.

Something which we rarely mention here is in some barrels and bullet profiles the OAL can also be used to fix feed issues. Too short an OAL can hit low on the feed ramp and cause a mis-feed. I have a 40SW which feeds most reliably at an OAL is 1.18+. I had to switch to 10mm mags to run that length. Oh the fun of the sport.

I used PD FMJ 147 RN for years and what I found is the jacket is the hardest FMJ out there. On some brass sized with Dillon die (basically same as Lee U die) the brass would bulge as the bullet is seated. The worst offender is CBC brass with the thickest side walls and quickest taper to the base. Solution is this, use a neck expander of .355 to pre expand, the MBF powder funnel to give a proper flair, the Hornady seating die (the one with the collar guiding the bullet in) and the Dillon taper crimp. This reduced my bulged brass with PD FMJ to a minimum, because the bullet seated straighter. Again, PD FMJ bullets are very robust, and the brass gives before the bullet does as it is seated. Plated and coated bullets tend to get swaged down a little bit as they are seated into the brass. Don't forget HP has a completely wrapped base causing them to be even more resistant to being swaged down than the open base RNs. Another thing to try is shooting some One Shot on the bullets, not the brass, and see if more lubricity helps them seat smoother. Hope this helps.

If you read my post that's exactly what I wrote: "I've converted a gun to SAO for Limited years ago and the only advantage was I added a flat trigger, " I agree if one wants a flat trigger or some other trigger shoe option then LO is the division to shoot. But to state there's huge advantage to SAO conversion just isn't true. I put a mag well on one of my guns, it already has an extended safety for my thumb (legal in CO) and presto LO gun. Start hammer back safety on in SA.

So instead of insulting, you really need to point out where you think this is wrong. This is known as a discussion not an insult. My example comes from experience with the gun after 10s of thousands of rounds. So where is this wrong, give examples please.

You missed the point. "The glorious thing about reloading is customizing the rounds for the gun one owns. Finding the load for accuracy, gas pressures (cycling of bolt), and more is what it's about." I know there are exceptions, however I don't know of anyone in my circle of 223/5.56 reloaders who state they are reloading for one or the other. They reload to maximize the gun. It doesn't matter what chamber is in the gun one loads for. What matters is accuracy and loads that feed and work for every shot. Pressure management is no different when developing loads. Some barrels can handle more than others, that is part of the process.
