Did you do the plunk test?

I thought I posted a response, but I don't see it.
Yes, David. They all plunk very nicely, and cycle by hand very smoothly thru my 1911s.
Thanks for a response!

The results are in--HAPPY, HAPPY!

It didn't start well at the range today, but it got better.
I was going to 'warm up' the pistols with a few of the wife's bunny fart rounds, and on the second round out of the revolver I had a SQUIB!
After removing that, it got a lot better.

All rounds tested were with Precision Bullets 200gr SWCs using Magtech brass and WLPs. COL is 1.255 and crimp is .471.

3.8gr--Recoil is soft.
Function is 81.25% (3 FTEs in 16 shots. 1911 not happy)
Accuracy is OK, but hits high.
Guns are both clean.

4.0gr--Recoil is still fairly soft.
Function is 100% (Me and 1911 HAPPY!)
Accuracy is better, hits to POA, and the group shrank a little.
Guns are both still quite clean.

4.2gr--Recoil is a little snappy, but still moderate.
Function is still 100%.
Accuracy is basically the same, but hits a little low.
Guns are both still surprisingly clean.

The verdict--4.0gr is the winner!
There is zero leading at these loads , and very little carbon or other crud to clean.
4.0gr shoots great, and runs 100% in my 1911.
What more can you ask for?
I am basically a HAPPY CAMPER!! (In case you couldn't tell)
Do any of you think it will be worthwhile to play with the COL a little each way to see if the accuracy can be improved?
Thanks for the input!

Edit-- I just realized that if I removed the Shok Buf from the 1911 it may function at the 3.8gr load, and the POI may change. When I can, I will try it, and let you know what difference it makes.

If your loads feed in the magazine and pass the plunk test, its all you can do.

I read you made the rounds just short enough to fit the magazine. They will work fine.

I used Clays. I tried 3.9 with a powder coated 200 SWC. It would almost make my 3.5" officers model operate. I cannot change springs on this one, so I wanted minimum that would still function.

I went up to 4.0 Clays and function was perfect. I loaded about 700 of those for bowling pins. I loaded another 300 with 4.4 (max in the book) using my oldest mismatched brass. Kind of disposable rounds. I loaded some 45 colt rounds to use up the full 14 oz can of Clays.

I have crony figures, but now here at work.

David,
According to Hodgdon, these rounds should be 0.030" shorter than they are, and I have about 0.025" between the bullets and the magazine shell.
However, I doubt going shorter would improve accuracy at all, and going longer than the magazines will feed still won't get the bullets to the lands.
SW1911 E Series pistols have a LONG chamber. Unless I put a 'Match' barrel in it, you are right.There are no advantages to changing the COL.
I just removed the recoil buffer from both 1911s. I don't shoot heavy loads or +P ammo any more, so I won't need them.
Without the buffers, I think these pistols will cycle properly with the 3.8gr load.
I will load a few, and see. If they cycle OK, then the POI is the only thing left to consider.
If it hits closer to POA than before, then I will make that my pet Clays load.
If not, I will bump back up to 4.0gr and go with it. They shot very well.

4.0 Clay's, federal match primer.

5" 784 av
3.5" 674 fps av for a 10 shot string. Don't have SD. Was not much.

My OAL has just enough shoulder to touch the leade. I have a Wilson's match barrel.

Enjoy
David

I see a match barrel in my future.
Even at 1.275 they wouldn't contact the leads, and they scraped the inside of the magazines.
Fine for casual plinking, but I like to make single holes with 8 round magazines.

When I'm too lazy to cast my own, I use MIssouri Bullet Company's .45 cal., 200 gr TWC (a dead ringer for the old H&G #68 target bullet). That MBC TWC is as accurate as any factory loaded .45 target round that I've tested, and is a good deal cheaper...you can do no better! Rod

Rod,
I looked at MBCs .452" 200gr offerings, and I didn't see a TWC.
The Bullseye #1 looks perfect, though. The price is competitive too.
Thanks!
I have been at the bullet casting subforum and the castboolits forum a lot lately. I think casting may be added to my reloading addiction pretty soon!
