alzo Posted September 10, 2006 Share Posted September 10, 2006 I am working up a new (for me) load with 230gr Zero JHP's and N310 for use in USPSA Single Stack. Power factor will be 165-170, more likely 168-170. Is a lighter recoil spring called for with this type of load ? I have seen some recommendations for a 14lb spring. I have no experience with lighter loads like this. I am used to standard hardball equivalent ammo and an 18.5lb spring. Link to comment Share on other sites More sharing options...
Merlin Orr Posted September 10, 2006 Share Posted September 10, 2006 I think a 14 is enough...I have used 14 and 16 springs and the 14 seems to have less "dip" than the 16 for me. Similar load to yours with 230 Precisions and Clays powder.... I do not use a buffer on any of my guns. YMMV. Link to comment Share on other sites More sharing options...
Vlad Posted September 10, 2006 Share Posted September 10, 2006 Try a variable rate 15lb spring. They rock. Link to comment Share on other sites More sharing options...
HSMITH Posted September 11, 2006 Share Posted September 11, 2006 I run a 14 most of the time, played with a 12 and it shows real promise but 14 works every time on time. I have a hard time messing with what I am used to when it works well. Whether I run a buffer or not tends to hinge on what sort of mood I was in last time I had the gun apart. I certainly don't think they are needed with a 14 pound spring and the load you propose. Link to comment Share on other sites More sharing options...
Carmoney Posted September 11, 2006 Share Posted September 11, 2006 I've been using a 13# spring (and no buffer) for IPSC major loads for the last year or so, with excellent results. Link to comment Share on other sites More sharing options...
Nemo Posted September 11, 2006 Share Posted September 11, 2006 +1 for the 14 lbs. Link to comment Share on other sites More sharing options...
JFD Posted September 11, 2006 Share Posted September 11, 2006 14 lb for sure. Huge difference between that and having waaaaaaay more spring than a 1911 needs with these loads. Link to comment Share on other sites More sharing options...

nipplehead Posted September 13, 2006 Share Posted September 13, 2006 I have been using your exact powder and bullet wieght for 2 years in my 1911. 4.2 VV 310 made major in my gun. I like a 13lb spring with a wilson buff ...the buffs never tearup but I still change them periodically. Very soft and no reliablity issues.

Mick Posted September 14, 2006 Share Posted September 14, 2006 I only load my .45s now with 4.0 grains of Clays under the Precision Bullets 230 gr round nose. I get about 775 fps depending on the gun and have used an ISMI 16# spring with this combo for years... Mick A27257 Link to comment Share on other sites More sharing options...
Joe D Posted September 22, 2006 Share Posted September 22, 2006 Buy several and see which one suits your style. I run an 11# spring in my Kimber. A 12.5 works for me also. Remember, the lighter you go the more accurate the feed cycle has to be. A heavy spring will mask feed problems. Link to comment Share on other sites More sharing options...
Waltermitty Posted September 22, 2006 Share Posted September 22, 2006 (edited) One method to try is to buy a spring pack (like the Wolff product) that comes with one each of a range of weights. Put a new shock buff in your gun. Start at one step below where you are now and try to do you best double tap. Note the distance between the holes. Step down one spring and repeat the process. Find the spring that gives the best (smallest) spread. Put another new shock buff in and go to a match. Inspect the buff after every stage. Find the balance you like best. In my hand a 9 lb spring in my .40 gives the best double tap, but the buffs won't make it through some long stages. I can get about 500 rounds on a buff with a 13# variable rate spring. That's what I run in my Limited gun. The Wife runs the 9# in her Open, and I lose the buff before it wears out. When buff life drops off, replace the spring with a new one.

Steve J Posted September 24, 2006 Share Posted September 24, 2006 (edited) Really good advice here from wise sages. When I get a lot of good range time again, I'll have to try Waltermitty's method. I'll add my experience even though I'm neither wise, nor a sage. I too am used to factory hardball loads in competition, but I wanted to try a walk on the wild side. I experimented with 168-172 pf with Clays with a 14# spring and didn't like it. I didn't like the way the slide cycled. I wasn't timed to it. It didn't feel right. So, here's what I'm going to do. I bought a more versatile powder. I wanted AA#2, but Sportsman's Warehouse was out, so I went with Power Pistol and I'm going to work up a load that's feels slightly lighter than the softest factory load that I've found (which is Wolf) using a VP 16.5# spring and go from there. Get used to it, then gradually take it down a step at a time until I don't like how the gun cycles any more. That's my plan. I personally just really don't like the way a .45 cycles at 170pf with a 14# spring, but that's just me. p.s. if you shoot indoors, Clays is really smokey even with FMJ.

nontactical Posted September 24, 2006 Share Posted September 24, 2006 11-13# (depending on you), one shock buff. If the gun is set up right this is ssswwweeeet. Link to comment Share on other sites More sharing options...
f250sd Posted October 1, 2006 Share Posted October 1, 2006 I use a 11# in my Springfield Trophy Match with a buff. Zero feed or ejection problems. Link to comment Share on other sites More sharing options...
steel1212 Posted October 3, 2006 Share Posted October 3, 2006 I just had a problem running a 14# spring and a buff. The gun would not release the slide if racking from slide lock. I removed the buff and all worked as it should. My question is if your running lower than a 14# spring and a buff can you rack your slide from slide lock?

Run n Gun Posted October 3, 2006 Share Posted October 3, 2006 Usually not. There's a mechanical limit to how far the slide moves on the frame, the shok-buff goes in between causing the slide to hit it rather than the frame. The end result is that with a shok-buff installed the slide won't come back as far, and that is why you can't "slingshot" the slide. The only time the spring or spring weight is involved is if the spring is "coil binding" and that's a VERY rare condition. Ed Link to comment Share on other sites More sharing options...

TIA Cheers Manu I settled on the 3.8gr charge listed below. All are COL=1.215", 0.469" crimp. I stuck with my 18.5lb spring and haven't had any problems. These velocities are from a 5" Kimber. I get about 7fps less from my 5" Wilson.

I have found at least one brand new spring still in original packaging that had coil bind even without a buffer (checked with a SDM spring tester).
