I load Berry's 230-gr plated round nose over 5.3 grains of Winchester 231 and I get about 775 fps. What bullets are you using?

The average shooter probably isn't going to wear out a spring.
Otherwise, it's easier to adhere to a maintenance schedule and replace it every so many thousand rounds according to manufacturer recommendations. |

As Aquila Blanca (and I) noted, guns don't generally malfunction that much until a recoil or magazine spring has degraded quite a bit. A coil spring can break, but that sort of failure is seldom a function of long-term usage; it can happen early in a spring's service life. Typically, coil springs get softer over their life, but some seem to last forever if the gun design doesn't push the springs too far.
Knowing how much a spring's resistance has weakened will be information, but until you hit some threshold -- which will arguably be a threshold YOU define if the gun continues to function with a weakened spring -- when to change springs is something only YOU can decide, and it could be a very subjective decision. It would seem, too, that the threshold you set could be different from gun design to gun design, or if you shoot just one type of gun or a single gun, from spring weight to spring weight, from spring design to spring design, and might also be somewhat affected by the loads used (with hotter loads maybe needing stronger springs than weaker loads). How do you make that information you're accumulating useful? (The number of cycles suggested by some gun makers -- which they don't seem to do as much as they once did -- seems more about them covering their butts and holding down customer service calls -- than a useful guideline.) I wonder if the spring makers have any suggestions about how to assess spring performance? Last edited by Walt Sherrill; January 18, 2018 at 10:35 AM. |

Walt...I agree,
I think it was probably a flaw in the steel....that caused the recoil sping to break in my 5" 1911....vs anything a spring tester would tell me. More than anything, I used the failure to justify trying something new & converting it to a Flat Spring... so far the Flat Spring has only been in the gun for about 2 weeks ( so only about 20 boxes thru gun on that spring / 1,000 rds )....FWIW, the gun has run 100% on the new flat spring, the new FLGR ...and it feels the same vs the old FLGR & traditional coil spring ...gun was very smooth before...same now. The new FLGR - new Flat spring & new end cap is approx 1/2 oz lighter....than the previous FLGR, spring & end cap...and in a 45 oz gun, I can't tell the difference. Other than spring life ( wilson combat says about 4,000 rd life on a standard recoil spring, 20,000 rds on a CS spring ..and they expect 40,000 rds on flat spring ...)...so we'll see ...( in that Wilson, 5" all stainless 9mm - I run about 20,000 rds a yr of my reloads, 115 gr FMJ Montana Gold bullet, 4.7 gr TiteGroup @ about 1145 fps....) ...so its an average load. |
