Quick Load request

[truck driver]

Hi Guys I need a quick load for .45 acp using Accurate SOLO 1000.
185 gr lead SWC 5in barrel Sammi pressure.
This is for a custom 1911 target pistol.

Thanks

A quick glance fails to show lead bullets in the weight you requested, Rodger. Here is a projection with the Hornady 185 grain SWC, however.

I would be more comfortable with the data provided by the manufacturers, but that is just me.

Thanks DrMike,
For the looks of the prediction I'm with you about the data.
That looks a little hot to me for my use. I'm only looking for 750fps-800fps. That looks more like the old Winchester .45 magnum pistol velocities.

Thanks for the chart.

Truck driver you can get the full data here

It has a listing for lead, but not with the powder you want

Thanks I saw that when I accessed the data. But the powder is there as S1000 just the bullet weight I use isn't.
I can take the charge for the 200gr LWC and adjust it for my purposes.
Thanks for the help.

 

[truck driver]

Thanks everyone for your help I settled on a starting load of 4grs and a match load of 4.2grs under the ZERO 185gr LSWCHP. I might use the same powder charge for the 185gr Nosler JHP which is also a very accurate pistol bullet.

Let us know how it shoots

Let us know how it shoots

Here you go some pictures of a couple of targets shot at 25yds. First target is 10 shots fired in two 5 shot strings in 20 seconds the second target is ten shots rested from 25yds. I adjusted the windage and then shot the two 5 shot strings.

 

[DrMike]

Given the conditions you imposed on yourself, these are a couple of fine targets, Rodger.

Thanks DrMike, but to be honest I need to improve the off hand target since I shoot in hand gun matches and I'm trying to prepare to shoot in the National Bullseye competitions at Camp Perry next month.
That off hand target would be acceptable for the rapid fire phase which is two 5 shot strings, 10 seconds for each 5 shot string.

Rodger , this is the combo I shot bullseye with too solo1000 with a 185 cast lead bullet .it's been awhile since I've shoot it , so I had to look . I was down to 3.7 grains of solo1000 . I shot best at 4.0 grains .

Thanks for the info Jim, With my set up the 4.2gr load is still a little light so I will increase it a few tenths till I get full reliable function. Though this load shoots good it's still a tad lite for my liking and my recoil spring is as lite as I can go for proper feed and lock up.

Nice shooting Roger!

Thanks Dan I still have a month to get tuned up, so I hope I'm at my peak when I attend the match.
