To keep things simple i will just refer to 45 colt standard pressure (14k) loads with .451/.452 projectiles.
As we all know the availability of .451/451 projectiles is huge and numerous, varrying in weights from 135grains to 400 grains. Comprised of all lead, copper or brass jacketed, copper plated, and even solid copper projectiles. In various configurations from hollow point, fmj, jhp, swc, rn, fp, xtp, xp, xd, fracturing, and and even those can be in multiple configurations.
Obviously all these factors have an effect on friction in the barrel as well, increasing or decreasing. The resistance obviously having an effect on pressures.
Then of course we have dozens of different powders we can use as well. Obviously some powders work better with one projectile in the same gun and not so well with others. ie.... powder A might work great with a 185gr jhp while powder B works better with a 250gr FPFMJ.
Thats all logical and to be expected. Im not the least bit surprised by that information.
My complaint comes from the publishers of various different loading manuals. I do have the latest editions from Western powders, Hornady and Lyman, as well as individual load data from Lehigh Defense for some of their projectiles.
The combination of these manuals is awesome. I have learned a-lot. I do understand that at least in physical printed form one cant list load data for every powder with every possible projectile. I think though with the internet it could easily be possible though. Input the powder you want, the projectile, and your caliber casing and then it outputs the appropriate info.
Thus my complaint. I have projectiles that i wish to use for my colt 45 loads that i know perfectly well and logically speaking there is no reason why they couldnt be used safely and effectively in my colt 45’s. By effectively i mean creating a consistent accurate load for the purpose needed.
Example a 250 grain flat nose copper plated projectile. I cant find any load data for this bullet.
Nor can i find one for a 185grain hornady XTP.
Yet i can find load data for 185gr JHP, or 250grain FMJ’s etc etc...
Maybe for long time handloaders you know how to work around these issues. I am still a newbie and i openly admit i dont have enough knowledge to know what would be a safe starting point. I am smart enough to figure out logically what maybe possible, but feel like i lack enough know how to be safe.
So that is why i have this post.
When you have a projectile that you know logically can be used, but cant find data for it. How do you figure out what load to start safely using it?
I have 3 projectiles i would like to use in my colt 45’s at standard pressure.
Using any of the following powders
Power Pistol
Accurate #5
Unique
The projectiles
250 grain Flat Point full Copper plated
185 grain Hornady XTP
230 grain RN Full copper plate “FMJ”
Hornady lists their 250gr xtp with acc #5 at 7.7 to 9.9
Western lists the same projectile at 9.9 to 11 with the same #5.
Why the diff? Which one? But i also do have that projectile. Western lists the 200 grain XTP with #5 at 10.4 to 11.5 and a 230 grain XTP at 9.9 to 11.
So what should i use for a 185grain XTP?
They list a 185grain JHP at 10.8 to 12?
Which leaves me wondering about my 230grain and 250 grain “fmj” rn and fp projectiles.
Thoughts?
