jrguar Posted September 21, 2023 Share Posted September 21, 2023 Trying some Blue 147's in my prodigy, curious about what LOA do you guys think works well. Am basically to 126-127 PF and currently running 1.130 ... Inquiring minds want to know ;0 Link to comment Share on other sites More sharing options...

jrguar Posted September 29, 2023 Author Share Posted September 29, 2023 I ran a bunch of measurements and decided that 1.140 is about where the prodigy likes it, my X5 I can load out to 1.165 or so and no issues so I think we are going to stick to 1.14 for a while...

Joe Bullet profile plays a huge role in this also. I've found RMR JHP have a "fat" ogive and what loaded fine in my X5 at 1.115 needed to be pushed back to around 1.08. Similar situation with the RMR FMJ; needed to push them in a just a tad; even 1.125 wouldn't pass a plunk test but would load and shoot ok.

GunBugBit Posted October 24, 2023 Share Posted October 24, 2023 Good to know 1.140 works for the Prodigy. The loads I use for a PM-9 and a Glock are that length and I’m considering getting a Prodigy. Link to comment Share on other sites More sharing options...

I picked up another Prodigy and what do you know but this one is perfectly fine with the same loads that caused problems in Prodigy #1. Even with the rather fat RMR 124 JHP profile I could load those out to at least 1.125 which is way beyond where you would typically load a 124 JHP for 9mm minor. RMR 124 RN were fine at 1.135 which is as long as I've ever cared to load them in any of my 9mm guns. Other aspects of the two guns are significantly different as well. Kinda makes me wonder about Springfield manufacturing tolerances and quality checks... Link to comment Share on other sites More sharing options...

GunBugBit Posted October 25, 2023 Share Posted October 25, 2023 Over-tight chamber is one of my least favorite things. Link to comment Share on other sites More sharing options...

You can always ream to fit, it’s a bitch welding them up. Of my 6 Springfield variants, there is only around .002” difference in throat depth between same calibers. Yes they are short but I thought that was pretty good for a production firearms. Edited October 25, 2023 by Farmer Link to comment Share on other sites More sharing options...
GunBugBit Posted October 25, 2023 Share Posted October 25, 2023 I’ve been lucky with not having loose chambers. Yes that’s worse. Link to comment Share on other sites More sharing options...
