MrDesertBrat Posted June 22, 2015 Share Posted June 22, 2015 (edited) Folks, I am planning on trying some Steel Challenge events, Limited class with a modified M&P Pro 9mm. Since one of the key elements is getting the gun back on target ASAP, I was considering lowering the recoil to assist on quicker target acquisition. I am willing to tweak the recoil spring weight to help, and use lighter loads.. thus I ask: 1. Anyone know of a good, consistent load with Win 231 (have 8lbs to use up) that has low recoil? 2. Has anyone developed at good non-compensated 9mm load in general for steel? If so what might it be? 3. Am I reading too much into this - aka, just go with what I know - 124 Berry HBFP over 4.5 grs Win 231 with Fed Primers. 4. If I lighten the bullet (say 100gr), lighten the load (3.8 Win231), use a lighter spring - will it make much of a difference in recoil/recovery time? Thanks Folks..

Hi-Power Jack Posted June 22, 2015 Share Posted June 22, 2015 My vote goes for lighter bullets (if you don't have to make PF). I've shot Very Light (100 PF) 115 gr bullets over 3.1 gr WW231 and it is Very Easy to recover. But, check your reliability and accuracy at desired ranges.

Bkreutz Posted June 22, 2015 Share Posted June 22, 2015 I'd say shoot what you are familiar with, any time you change things you run the risk of "unintended" results. When I shoot Steel Challenge, I still use my USPSA major loads because that's what I shoot most of the time. But then again, I'm easily confused.

warpspeed Posted June 23, 2015 Share Posted June 23, 2015 For SC, I like a 115 gr load that chronos at 1000 - 1050 fps. My shooting partner who is way better than me runs a load closer to 900 fps IIRC but it takes a gun set up special to run that light 100% and for a non-dedicated SC gun, I feel better with a little heavier load.

ZackJones Posted June 23, 2015 Share Posted June 23, 2015 I've been playing around with some ultra light steel loads and I was working with the Bayou 95grain bullet. I've since sold both of the pistols I was testing with but once I get another 9mm I'll get back to testing. I would start with your current pet load and decrease the charge weight by a couple of tenths and see how things feel. Keep working your way down until you get a load that you like. I will say the 95 grain bullet with 4.0g of TiteGroup or 4.0g of e3 is probably one of the lightest loads I've ever shot. You'll want to go with a lighter recoil spring for sure.

MrDesertBrat Posted June 23, 2015 Author Share Posted June 23, 2015 Thanks folks. The gun is being assembled for SC and an IDPA ESP back up if I need it (I shoot and M&P Pro in SSP). I can easily have several "captured" recoil springs to drop in so adjusting to light load and then returning to the IDPA 125 PF will be a breeze if I need to. Zack, interesting approach 95 grains bullets.. hmmm... how was the 20 yrd accuracy? What weight recoil spring did you use? Warp, I am assuming he did not have an issue stabilizing the 115gr at 900 fps? Do you know what spring weight he used on the gun? Hi-Power, damn son, 3.1grs .. wow... for a PF of 100 that's about 870 FPS .. any issues stabilizing the bullet? Was the Bullet Jacketed, Plated, or Cast? Thanks All..Very much appreciated.

Pasley Posted June 23, 2015 Share Posted June 23, 2015 I load 4.8 grains of N340 with a 115 grain bullet. That is as light as seems reliable with a factory Glock recoil spring. I periodically think about getting a lighter after market spring. Link to comment Share on other sites More sharing options...
dave33 Posted June 23, 2015 Share Posted June 23, 2015 My steel challenge load is 3.4gr of titegroup under a 100gr SWC from Ibejiheads. It makes about 109PF and is pretty accurate, it will shoot about 3" groups at 25yds, not a bullseye load but sufficient for what I use it for. There is basically no recoil. I shoot this load out of my XDM 5.25, which is the same gun I shoot for all comps, and it functions fine with a 14lb recoil spring. It has a trigger kit in it as well with a reduced power striker spring so that probably help function with super light loads. If your gun will feed SWC's ( I would think an M&P should ) this is a great load. I have tried some of the 95gr bullets, couldnt get any kind of accuracy with them no matter what load I tried. Probably not enough bearing surface for my XDM to get hold of. I have thought about trying some of the 90gr Hornady HAP bullets but havent gotten around to that yet.

I didn't get a chance to test any groups before I sold the guns. I'll try again whenever I get another 9mm. Link to comment Share on other sites More sharing options...
missed it by that much Posted June 25, 2015 Share Posted June 25, 2015 What OAL was that on the 100 grain swc as I have the same gun and would like to play with that recipe Link to comment Share on other sites More sharing options...
dave33 Posted June 25, 2015 Share Posted June 25, 2015 What OAL was that on the 100 grain swc as I have the same gun and would like to play with that recipe 1.03 OAL is what I usually load to, but have done batches from 1.02-1.04 and they all work fine. I get the bullets sized to .357 though. Link to comment Share on other sites More sharing options...
EngineerEli Posted June 25, 2015 Share Posted June 25, 2015 I would wonder if you could do a similar thing to when people switch their Major .40 loads to minor for 3gun by just dropping from a 180gr to something like a 165 or 155gr. I would think if your normal Production Minor PF load is with a 124 or a 147 you could just change the bullet out to a 115 but leave everything else the same and end up somewhere in the ballpark of where you want to be? No adjustment of the press itself at all. Link to comment Share on other sites More sharing options...
Taroman Posted June 25, 2015 Share Posted June 25, 2015 For steel challenge, I load the Bayou coated 135 over 2.8 grains of Bullseye. Federal SP magnum primer 874 FPS with SD of 9.01. Tried standard primers and the ES and SD were larger. This is for my S&W 986 revolver. Link to comment Share on other sites More sharing options...
Jrb305 Posted June 26, 2015 Share Posted June 26, 2015 (edited) I'm using 3.8 grains of 700x and an Xtreme 124gr bullet. Edited June 26, 2015 by Jrb305 Link to comment Share on other sites More sharing options...
LikesToShoot Posted June 26, 2015 Share Posted June 26, 2015 C.J. I vote #3, just go with what works for you right now. One less bullet and ammo can to keep track of. What's the PF of your current load? You may want to consider just dropping your charge back a little bit to see how it works for you. Many of us have gone down this path you're looking at and have the extra springs and bullets to prove it. Since you'll be calling your shots it'll just be transitions you'll be working with between shots. Tweaking an M&P isn't like tweaking a 2011/1911..

No issue at all - I think he runs a 5# and even that has a few coils cut off. Link to comment Share on other sites More sharing options...
echotango Posted July 23, 2015 Share Posted July 23, 2015 I'm running mg 115gr w/5.2 autcomp for a 120pf. Will start playing with a lighter load. Link to comment Share on other sites More sharing options...
Skywatcher Posted October 21, 2015 Share Posted October 21, 2015 well i dont use 231/hp38 as its dirty in my guns and to much flip but i use 4.0 n320 with 115 plated for 117pf and is accurate and light recoil for fast recovery Link to comment Share on other sites More sharing options...
Nebwake Posted October 21, 2015 Share Posted October 21, 2015 I run 3.2 gns titegroup under a 115 gn FMJ with WSP primers. SUPER light and fast but this is in my STI trojan 9mm steel gun with light springs. This load will not reliably run my Glock 34 with the 13# spring. But I LOVE it with my trojan.
