Thanks! The Ransom Rest is the contributing factor in these tests!

@DirtyB This applies to most pistols: https://czfirearms.us/index.php?topic=103620.0

OAL? Check both (all) pistols that you’ll be using this load in for optimal OAL! Load for the shortest one. I like ~1.120” OAL but YOUR GUN(s) may need something different. My powder charge is displayed on the target above, but start out below that and work up to what your pistol likes! Safety above everything else when developing a load!

Ah.....now I understand your displeasure with Federal primers not working in your primer equipment! Yea, must be a lot of shooters that like Federal...........I noticed they were the #1 used primer in Production and Carry Optics for the last 2 years as reported in the USPSA Equipment Surveys. I apologize to @boatdoc173 for taking the thread off-subject.........

Yes, I noticed you stated it's not the press............. I was simply addressing my experience with Federal primers and that I did not think they suck............

@Leezway 3.3g N320 behind a Blue Bullets 147g gave similar accuracy results as above......... Average FPS: 917 Spread: 25 SD: 7

As @GrumpyOnestated, 3.5g of N320 behind a quality JHP will yield awesome results in the right pistol............ Example from my S2 Orange: Average FPS 902 (10 shots) Spread 13 SD 4

@GrumpyOne Sounds like a great time to make a video of your process! I’m sure it would benefit other 550B operators!

@boatdoc173Something you might want to consider............ you could send your mixed brass to a commercial sorter/seller, and for a reasonable fee, they would sell you back your own brass in about any configuration you may need. All same headstamp and FULLY PROCESSED!

@Racinready300ex Been loading with nothing but Federal Match SP primes for MANY years, and in my experience, they are without fault in the RL1100 or previous XL650s. I usually load in passes of 500-1K; and just load up however many I need using Dillon PPU tubes with my PAL Filler. If my machines priming system is clean, I have "0" upside down primers............

I agree with this guy's statement: And I definitely respect Bruce Gray's comment:

As someone that recently transitioned over to RDSs, I totally agree with @ddc on this!

@oddjobSent you a PM........

Like @Boomstick303recommended, watching this video should shed some light on the interaction of the TSL (takedown safety lever) and the slide release! https://youtu.be/MjRYRTGe2eQ The Slide Stop Lever and the Takedown Safety Lever definitely interact; and can give us problems if they are not in the correct positions during reassembly!

If you do Facebook, I would take a look at Robert's video that IMO has some great selling points! And I think one of the reasons that I personally like the TSA Competition Trigger System is how much it feels like a 1911 trigger! https://fb.watch/g7aj2gP7UH/

Great idea! I definitely like to use Excel.......

For the price, it's got a ton of features and bolts up to the P322 without any adapter plates. However, I did re-mount the optic using the way overpriced Sig mounting screws.................. https://www.sigsauer.com/romeozero-mounting-screw-kit-p365x-or-p365xl.html Just a bit more stability IMO.......

And this one gives some very good insight into what makes the TSA mods work so well......... https://youtu.be/6Ym852bbrCc

Been there.......done that!

Haven't seen anything available yet............ FWIW, I installed the Holosun 407K X2, and it works perfectly!

The TSA Accessibility Tool definitely works and is a big help with the FCU!

Thanks EVERYONE for the feedback! Definitely IOS on my end...........so I'll be waiting on the BT version.
