45 ACP Load

[magshooter]

Does anyone have a 45 ACP load for 185gr FMJ titegroup powder?

I have a load for this that calls for a large primer 45 ACP cartridges but does anyone have a small primer load for this?

Would the primer size matter?

 

[cheygriz]

I use "standard" 45 ACP data.

Use the same load.

All the .45 loads in all my books call for large primer but they don't seat very well in brass with small primer holes.

I loaded some of the large primer loads with the small primers and they were not as accurate and they were not as smooth as the large primers. I was hoping someone else could give me some more information on this now that I experienced first hand that they do not feel the same when fired.

I can't tell the difference myself. I mostly load with Bullseye powder, Tula primers, & I'm still using MBC lead bullets. Maybe try faster powder.

I can't tell a difference using SP brass. I load the same. I assume your SP were fresh, stored correctly, good brand?

I only load SPP 45 ACP. I found no difference going from LPP to SPP Try again as it seems maybe you made a mistake.

I tested small vs. large primers a number of years ago and found no difference in accuracy or velocity. The velocities were within range of each other i.e. one did not have more variation than the other. I would not have noticed any difference if I weren't testing. The loads were all 5.0gr of Bulleye and a 230gr RN. The old standby.

According to all the sources I have read there is no difference at all in load data when using 45 ACP brass with large or small primers. None! There are no pressure differences reported by the powder companies or load manuals.

Chalk up another "no difference" here - I use all .45 ACP loads interchangeably between SPP and LPP

Interesting, I found just the opposite. The small primer loads were more accurate for me.

Shooting them over the crony shows the SP produces ~25-35 fps slower. So if your shooting for min you need to be aware that they will give you a slower velocity than LP.

Interesting information. Does this apply to all powders or just some?
Since most 185g loads in .45ACP get somewhere close to 1000 fps as the goal, 25 to 35 fps is likely not be noticed by most of us.
Competitive shooting puts a lot of variables into play and your observation is good for such people.

"...a small primer load..." No such thing. The load does not depend on the diameter of the primer. Just use regular 185 grain jacketed data.
