Loading 185 HPs for 1911?

[Capt. mike]

Haven't loaded 45 in a hot minute and never loaded anything beside 230 plated ball. I got some rainier 185 plated HP bullets and they are for my GI 1911 rock island. I remember having an issue with OAL in my last 1911 but OAL didn't matter to the glock. These are strictly for the 1911 so anybody have a sweet spot for the light HPs. Ill be going for 4 digits on these possibly higher, gonna use longshot as thats what I've been using for everything else but Ive got a pound of blue dot I can use too but cant find any loads for the 185s especially plated.

I'll check my notes, but I can't recall loading anything that light in years and years.

I remember thinking that when I picked these up

[Capt. mike]

I remember having a 1911 mag that had instructions on it stating that 1911s prefer x.xxx OAL for proper function.
I have 1.22 written down but its so old I cant remember if that was the before or after

I just checked Hodgdon's COAL data for .45ACP 185gr and all the list is a jacketed semi wadcutter.

They list that at 1.125.

However . . .

I find references for your bullet anywhere from 1.115 to 1.250

Now a tad of opinion based on experience; the right COAL is going to be very dependent on your individual pistol. Primarily three factors:

A) Barrel feed ramp throating.
B) Barrel ramp polishing.
C) Recoil spring "weight".

Were it me, I'd crank out a couple of dummy rounds, probably starting in the middle somewhere between 1.115 and 1.250 and see if they function smoothly manually feeding them. Then adjust in or out if necessary. That way you won't actually consume any of your components (as long as you have a bullet puller).

On cases that index off the mouth the plunk test is what I use...
The oal data is ok to get close, but the chamber will tell your oal length..

There are other post on this it is just the first one that came up..

I Agree with post 5...they all are diffrent..

The Hornady 230 XTPs that I have loaded in it are 1.24 so Im gonna start there and see where it goes

And to bring up another lively debate I only have a little bit of 45 brass laying around and most of it is SP. Is the small primer brass any stronger or weaker than LP. Im running wolf SP and LP in these

Lyman lists
185 jacketed swc 1.135 oal, and 185 jacketed hp 1.175

Lee lists
185 lead at 1.210 to 1.240
Lists 185 xtp at 1.200 to 1.230
Lists 185 jacketed at 1.135 to 1.210
(These are minimum oal- longshot is 1.135)

As to the sp brass, I use it when I can't or don't want to retrieve brass...

"Stronger" I don't have enough knowledge to voice an opinion I would be comfortable with.

But I can tell you that based on chronograph results small primers are a little "slower" than large primers. I'll normally bump a load up .1-.2 if I developed it using large primers then switch to small primer brass, in order to get the same velocity.
