jimbullet Posted March 27, 2022 Share Posted March 27, 2022 Just wanted to get your opinions. Im running 180gr, 40 S&W averaging at 1,027 fps to 1,030 fps. Is this too hot out of a standard 5 inch STI 2011 pistol or should it be fine? Its accurate in this setting so thinking to keep it at this level but not sure if this is ok.

Open1215 Posted March 27, 2022 Share Posted March 27, 2022 The velocity is fine if that's what concerns you. There is published data for longshot pushing a 180g bullet 1159fps at max load. It's more about pressure. What powder and what OAL. If you don't see pressure signs like Bulged cases flat primers I don't see why you would have any issues. Are you loading for limited? The PF seems a bit high but if it runs accurate and you like the recoil impulse, run it. Link to comment Share on other sites More sharing options...
Farmer Posted March 27, 2022 Share Posted March 27, 2022 Depending on your powder and bullet choice it could be. Need some more info. Link to comment Share on other sites More sharing options...
Postal Bob Posted March 27, 2022 Share Posted March 27, 2022 Like stated, depends on the pressure. Plus, if your running too light of a recoil spring, it could be pounding your frame too hard. Link to comment Share on other sites More sharing options...
NoSteel Posted March 27, 2022 Share Posted March 27, 2022 Another factor to consider is if you have any occurrence of bullet setback it could be bad.. Link to comment Share on other sites More sharing options...
jimbullet Posted March 27, 2022 Author Share Posted March 27, 2022 Im running Win231, 180 grain CMJ Extreme projectiles. OAL 1.160 - I kinda like the recoil impulse, snappy but then I was concerned whether I am just running the gun to death. Recoil spring 13 lbs.

I have read the pressure should not exceed 33,500 psi - but I am no scientist to ever know if Im exceeding that. My OAL is no longer in the reloading book - as we all 2011 shooters load long anyways. I run 13 lb recoil spring with shok buffs Edited March 27, 2022 by jimbullet Link to comment Share on other sites More sharing options...
RJH Posted March 27, 2022 Share Posted March 27, 2022 Why not just google hodgdon load data and see if your load is ok? Link to comment Share on other sites More sharing options...

I did, and max says 984 fps using xtp 180gr projectiles but that's for a OAL 1.124. Loading longer would alter psi and there is no info from there.

Farmer Posted March 28, 2022 Share Posted March 28, 2022 That’s funny, my Hodgdon manual shows 5.0g 231 XTP at 1.125= 947 fps @ 32900 psi. If your longer by .040 you shouldn’t have a problem if your at that grn loading. Hornady psi seems to run higher than many others, I’m thinking because of jacket material.

AHI Posted March 28, 2022 Share Posted March 28, 2022 You are at 185 ish power factor. I would reduce to 170ish Power factor. Your shoulder,back,rist. will thank you later on. Your gun will thank you. Your wallet will thank you. Link to comment Share on other sites More sharing options...

I kinda still have 500 rounds of these and it would be pain to use the bullet puller for all 500. So Im thinking to just shoot it since its been really accurate. In saying that, I dont want to blow up the pistol... Link to comment Share on other sites More sharing options...
AHI Posted March 30, 2022 Share Posted March 30, 2022 (edited) Doubt you will blow up your gun. You are probably at or above max pressure for 231 thow. Also doubt you'll be able to feel the difference in power factor. When you lower it. Especially on the clock so to speak.

usmc1974 Posted March 31, 2022 Share Posted March 31, 2022 The seems like a lot more PF then needed. 950 fps gives you 171. Just saying. Link to comment Share on other sites More sharing options...
