Loading 45Acp in Ruger SR1911

Mine get edited when I spot a typo after posting it, or I want to comment on another point, like I did about the question of how the OP's ammo looked. None were edited after another poster added their reply. GJ

I cleaned & lubed, and polished the feed ramp of my Taurus PT1911 and loaded up another 24 rounds with an added 1/4 turn of crimp and I had zero problems!

3.7 grns of TiteGroup under my Home cast/PC’d MP mould 227gr RNFP NLG .452 sized bullets with WRE LP primers.  

740fps,  168PF, STD Dev 11.4

MAXXTECH 230grn FMJ 

769fps, 176PF, std dev 25.0

I’ll take the Ruger SR1911 out next time now that the FEDEX guy showed up…. (Note I ordered 2! 🤪)

Yours were edited because you were wrong, called out on it and then you edited them. You do remember I have screen shots of your original posts….

What you thought you had to be bent about was about 4 years ago, and has nothing to do with this thread.

So….. you’re admitting to being wrong and having to edit your errors.….

[Garrison Joe]

Once.  I've even forgotten.  Can you?

It has been several times, Joe. And the problem is, when you post incorrect information, then edit it, who knows what is right or wrong? I would suggest, you proofread your posts before you post or only post what you have actual knowledge and experience of.

I'm still trying to figure out how a failure to return to battery and a failure to feed are different things in this context.  I suppose in this case, if the case still has bell in it because the crimp die hasn't knocked it out, it's both, since a round that doesn't fit in the chamber is never going to "feed."  This is a good time to share with the forum that I chamber check all of my ammo, and for wild bunch, my current tool that I use for that is my barrel, taken out of the gun and sometimes in front of the TV.  I figure any round that has been in the chamber before is likely to fit in it again.

 Chapo,

I also 100% case check all of my reloads as well with different checkers (Armanov, Lyman, EGW, Bear Metal Design, etc). depending upon the caliber.  As mentioned previously I ALSO chamber checked 100% of the rounds used in my testing.

in the end, I believe that the combination of the bullet shape, imperfections in my PC finish, insufficient crimp and lack of proper lubrication of my Taurus PT1911 and my Ruger SR1911 being brand new and not fully broken in all were-contributing factors.

my next range day will be dedicated to putting a bunch of OEM fMJ ammo through the Ruger to limber it up.

If those cartridges fit in your chamber, crimp was not the problem.

If imperfections in your powder coat caused failures to return to battery, I suggest shortening your COAL slightly to give yourself more margin for that.

Chapo, it seems you are correct about my assumptions from last night!

I spent the afternoon at the range again and frankly, now I think the main problem is Limp Wrist syndrome.

today, both handguns locked up on me multiple times using my reloads.  But Wait it happened again when I used the commercial rounds and I noticed a more significant muzzle flip.  

As I’ve said in earlier posts, the 1911 is a brand new platform for me and getting data on my reloads led me to use a pistol rest such that I could position my Athlon chrono right under the muzzle.  

So I reloaded all of the bad rounds into a mag and assumed the correct position and my Ruger and then my Taurus ate every round and 150 more without another issue.  

As such, I apparently wasn’t necessarily supporting the pistol properly and noticed how much my wrist was flexing with the heavier recoil from the commercial loadsIt seems that this recoil operated monster can’t handle a limp wrist

Doubt that is the problem based on the symptom.  If you limp wristed it probably would stovepipe.  If it ejects, there should be enough energy to feed.  The powders you're using are also not ideal for lower velocity .45 Auto, you really should consider using something faster like Clays or something close to it in the burn rate chart if you want to do that, or bumping up the load a bit, it will be more reliable.
