Maybe this is just a way to keep us hopeful  ;D
Gunsmithing / Re: Advice on spring rate needed

You're welcome.  I like testing and learning various things and it was interesting to see that Wolff meets their ratings on these springs.  It was also interesting to learn that there was more spring pressure at lock up as well... :D
Reloading 10mm ammo / Re: Loading for a Glock G40
« Last post by Ridgerunner665 on July 26, 2017, 05:04:17 PM »
Decided to try a 20# spring in the G40...the factory RSA has been working fine, no issues at all, but as I got used to shooting the pistol I noticed I can feel the slide bottoming out on the frame pretty hard.

Didn't notice it at first, but as I got accustomed to the feel and sound of shooting it...I noticed it quite handily.

Did some crude math and decided that for my slide/barrel weight (slide, 7" barrel, and a Leupold Deltapoint Pro) a 20 pound spring was more or less equal to a 24# spring on a bare topped G20 slide.

I got the Glockmeister version...I've always used Wolff springs but since they're behind the curve on the Gen 4 Glock assemblies I guess I'll see what ISMI is all about.

I wish someone would get some dual captured setups on the market in increased spring weights...I like the dual spring concept myself.
Data for the 10 mm over here is pretty pathetic, it is only there because AP70 is Hodgdon Universal,      AP100 is slower and looks like a better option, being equal in burn rate with 800x and AA#7,  contacted forums here for help but sadly there is little  experience here as only a handful of people have 10mm.  I'm sure they could be pushed to make a reasonable loading with ADI Powders,  but as a first time reloader without all the gear, it would be nice to have someone more experienced provide some data and velocity on ADI Powder loads they have worked up.      Maybe one of you guys over there in the land of the 2nd Amendment would like to have a play with ADI powders, or run it through your computer program and see how it looks and send me some generated data,   quite a few of what you use over there is simply just re-branded ADI Powders anyway

Overkill338,  I put the Wolff non captive dual recoil rod and springs in my G-29 and it has been great.  I have the 21 lbs which I keep inside it and also the 23 lbs but rarely use it except for testing...I use the 21lbs for 10mm/40S&W/357Sig and 9x25 Dillon from this neat little pistol...

Here is what I found when taking measurements:
Glock 29 spring test Wolff Gun Springs 21lb RSA installed
It takes 6lb 4oz to start the slide to move from the locked position
Full retraction at 21lb 3oz at lock open

Glock 29 spring test Wolff Gun Springs 23lb RSA installed
It takes 7lb 1oz to start the slide to move from the locked position
Full retraction at 23lb 5oz at lock open

Glock 29 Factory spring test
It takes 4lb 5oz to start the slide to move from the locked position
Full retraction at 16lb 10oz at lock open

Thank you for this post.  I had put heavier springs in a G20 before but never bothered with my G29's.  Don't know why but just after reading your post I ordered the 21# kit from Wolff.  The kit came in yesterday and I shot both G29's with it this morning.  Though only about 100 rounds were fired with it, they all fed & functioned perfectly.  The heavier loads were much easier to shoot.  Didn't try any real light loads but moderate to max were perfect. 

More testing is needed to make sure these results continue but it looks like money very well spent. 

Thanks again!
Handguns / Re: Colt is bringing back the Cobra

4" 44 Magnum/.45 LC Anaconda, or a .357 King Cobra?

Oops. Anaconda.

Bayan Dundee is in the land down under (Australia), he may have limitations that keep him at  particular bullet weight.
I have studied the ADI powders and data associated with them, yes they are sort of lacking but probably because they were never pushed to see just what is possible.

hunting feral pigs, muzzle energy is important, bullet weights will be 155/165 grain JHP.

I'm just wondering why you are limiting yourself to the .40S&W bullet weights?  You're holding 10mm - use a real 10mm!   ;D

To pricey for me, I am just going to buy a glock 29 and become somewhat of a gunsmith to make it function the way I want it to............
Gotcha.  I completely agree with that.  Too much data in the world that can be analyzed and used to show proper trends and causality.  I try very hard to be aware of base rate fallacy.
