Just get Blue Bullets and don't look back. Load em, shoot em, rinse and repeat. That will allow you to Worry about your practice and not your ammo. Sent from my SM-N975U using Tapatalk

Titegroup will probably be the most popular powder. 4.0 grains with a 124/125 FMJ Or 3.1/3.2 grains with a 147 FMJ Sent from my SM-N975U using Tapatalk

They will probably need to be loaded shorter which will change the charge weight. Have the same issue loading for the PPQ. Work up from minimum and find your happy place. Sent from my SM-N975U using Tapatalk

Sport Pistol seems to have taken hold as a good alternative to N320. It is far cheaper than N320 that is for sure. Some load data even looks like a 1:1 charge weight between N320 and Sport Pistol. You'll definitely want to do your own research and work up loads to find what works for you. I'm using Sport Pistol in 40 Major with 180 gr blue bullets and 9mm minor with 135gr blue bullets.

The goal is to build ammo that closely resembles the performance. I.e. The way the gun recoils and returns. So I'm mostly interested in the speed of their powder. I suppose to that end I could set up lines of powder and do semi scientific burn rate rate test. Sent from my SM-N975U using Tapatalk

Does anyone have any idea which power Atlanta Arms is currently using in their Select 135gr FMJ? Sent from my SM-N975U using Tapatalk

I used Alliant Power Pistol to test some RMR 124 JHP loaded at 1.08 OAL. It was based on a recipe from this forum and tested in a Walther PPQ SF - so a 5" barrel. **Standard disclaimers apply: Build workup loads backed off 10% from listed charge and check for pressure signs as you go. Using RP brass and Remington SP primers; 5.4 gr of Power Pistol pushed a RMR 124 JHP to a 10 shot average of 1165 for an average 144 power factor. The high end of these work up loads had a charge of 5.8 gr with a (ten shot) average of 1209 and 150 power factor. Alliant official data on their web page shows a Speer GDHP with an OAL of 1.12 in a 4 inch (test) barrel with CCI 500 primer using a charge weight of 6.4 for 1157

The throats on the Gen5 9mm barrels don't seem to be as 'long' as Gen4. I had to change my Gen4 pet load in order to pass the plunk in a gen5 barrel by shortening the OAL. As far as bullet diameter, my coated bullets are .356 but that's coated and not jacketed. I'd say the standard disclaimer applies - start low and work up.

Some folks have a lot of success doing it that way. However, this appears to be one of those times you may want to try seating and then crimping in two separate steps. Sent from my SM-N975U using Tapatalk

Seating and crimping in the same step? Sent from my SM-N975U using Tapatalk

Standard load workup process applies. The OAL will be your blend of "fits the mag and plunks the barrel" and charge weight will be a modest starting point based on closest weight/style bullet. We know from Xtreme FAQ that load data for their bullets is around the midrange point for jacket bullets. So perhaps a starting weight 10% lower than the minimum FMJ/JHP charge and work up in small intervals. Chrono for power factor or run until cycles - whichever meets your need.

I've heard of folks having great success with WST. One person mentioned using it because it seems to be a power that's still available during shortages. However, Without published data you"ll end up doing a lot of trial and error based on other people's data. Just be cognizant of the error part of that equation. I've switched to sport Pistol and not looked back. I keep a generuous supply on hand. Sent from my SM-N975U using Tapatalk

For what it's worth. After discussions as the Florida Open, the folks that were leading in PCC division recommend running a PCC in the low 140 power factor range. Best combination of cycle and dot tracking for shot calling. With that goal, I did tests over the summer with power coated, plated and jacketed bullets. The precision of those loads ranked in that order with full metal jacket turning in the smallest group. I tested a few powders like N320, WST, WSF, HP38, and Sport Pistol. 320 and Sport Pistol with Jacket ammo was the winning combination. YMMV Sent from my SM-N975U using Tapatalk

I switched to ASP from Titegroup in 9 minor and HP38/WIN231 in 40 Major. I tried N320 because that's the Voodoo. However, as others have found - my load data between N320 and ASP in both loads (9mm minor AND 40 Major) seemed to be pretty close; within .1 or .2 grains. Given that ASP was giving me what I want and ASP costs a little less I decided to go with that. ASP is giving me VERY acceptable accuracy. If N320 is going to CONSIDERABLY shrink the group size, then I'd consider it. I'd really like to see some temperature sensitivity data for both powders. My tests have been very limited because we just don't get very cold winters (for very long) and when it is cold enough to do decent testing - i can't make it to the range with the chrono. Anyway, I've heard that ASP isn't very temperature sensitive but I've also heard folks having problems on colder days. Not to thread jack, but if anyone can chime in with results, that is useful information for anyone considering which powder to use full time. Especially for folks that shoot Major matches.

I save the CCI for my 1911s with a 19# hammer spring. I use Winchester for the 2011s with a 17# and Remington primers for all things 9mm. I don't shoot many Glocks anymore but the couple I do shoot have 4.5# strike springs. All my primers get seated just below flush. Sent from my SM-N975U using Tapatalk

Sport Pistol has me covered in 9mm minor and 40 major Sent from my SM-N975U using Tapatalk

I picked a 1050 over a 650 as my second matching because of the primer pocket swage station. I came from a 550 and wanted to increase production rate without the need to add case prep (ream primer pockets) on 9mm brass. I'm loading 9mm and 40S&W to fuel my USPSA and other action shooting hobbies. The 550 loads my smaller quantity ammo. Anything that has needed to be replaced on my 1050 is pennies on the dollar really. Primer tube caps and some retaining clips. That's about it. Sent from my SM-N975U using Tapatalk

If the recoil pulse is significantly different then you can expect a point of impact shift. That introduces quite a few variables in your training that may lead to conscious thought on match day such as remembering holds or adjusting to the timing or feel of your match ammo.

Probably quality of internal components. The ol "you get what you pay for" is still true today. Just because things have gotten cheaper to manufacture doesn't mean they're better. If it were me, I would go with the lower set of numbers. Sent from my SM-N975U using Tapatalk

I loaded the RMR 124JHP bullets on a Dillon 550 and 1050. Nothing negative to say about them. Seating went just fine and they produced the most accurate group on the batch of testing against plated and coated bullets. Sent from my SM-N975U using Tapatalk

That stepped sidewall and thicker base cause major issues at the swage station (sta 2) on my 1050. Not to mention I have found some Xtreme "brass' that gets collected by the magnet All Xtreme gets thrown in the scrap bucket. Sent from my SM-N960U using Tapatalk

I'm pretty confident you'll like it. It does clean up super easy. My HP38 is left over from the switch to Sport Pistol. It has taken the place of HP38 in my 40major load. Sent from my SM-N960U using Tapatalk

HP38 will work on the low end but it's pretty dirty. I used some HP38 to finish off a stock of 124gr coated bullets. They run fine with standard springs but leaves a lot of carbon behind. Sent from my SM-N960U using Tapatalk

I used HP38 quite a bit in my 40S&W "XL" major loads and my practice 9mm. I have since switched to Sport Pistol for many of the reasons mentioned here. It's still very economical, it burns cleaner, and the gun stays noticeably cooler after strings of fire. Some folks may appreciate the higher case volume - making powder drops much easier to seem Sent from my SM-N960U using Tapatalk
