Non-listed bullet loadings

[7075-T7]

I have a thousand rounds of the montana gold 240gr JSP for my .44 magnum, and I'm slightly confused on the proper loading for the bullet, since I can't find it listed in any manuals.

I have a box of the Hornady 240gr XTP bullets and compared them to the 240gr JSP's, the crimp groove was the same distance from the base of the bullet and the JSP was ever so slightly shorter then the XTP. Figuring this, I used the Hornady book loads for the 240gr XTP since the JSP was slightly shorter, so at the same OAL (1.600") there would be more space above the powder and a little lower pressure, and wen't with 18.9-19.0gr of Alliant 2400 over a CCI 300 at 1.600".

I checked Alliants website and they said a 240gr GDHP load was 21gr of 2400 over CCI 300 at 1.575" COL so the 90% load would be 18.9gr.


Long story less long, was my line of thinking reasonable, and was the load I made up "good"?
Thanks for the help.

Great idea! I'll have to look into that for .44 magnum

You can NEVER have enough load data sources..!!!
I even have some OLD manuals that I have collected...Like the Lymans #1(its fun to look at old manuals and powders/primers/bullets used back then) ..!!!

Maybe I'm just strange or "sumpin" ?

Isn't it interesting to compare some of those loads from the old manuals to those today (.357 especially)?

I really like to look through the Shot Shell reloading manuals of back then right at the time they were changing from paper hulls to plastic ! I have an old Herters reload manual too that is fun to read, if you remember how he wrote things?
Everything they sold was the Worlds Best at Everything.
The paper shells when fired, had a distinct smell to them...not the powder, but the wax on the paper. (Maybe both?)
Plus it was kinda fun to build the wad column with fiber and cork and other materials. Now you just find the right plastic wad with the right shell and powder plus primer and your on your way. ( Might need some shot too?)

When I have a bullet that isn't listed in a reloading manual I will compare several load recommendations for similar bullet types. For example, I have a 115 gr 9mm FMJ bullet made by XYZ bullet company but there is no data for that particular bullet. I will look at data from ABC bullets, and from Blasto Powder Co. because I want to use Blasto Super Blast powder. So, ABC bullets says to use 5.5-6.5 grains of Super Blast with their 115 gr FMJ and Blasto says to use a maximum of 6.9 gr of Super blast with a 115 gr FMJ made by PDQ Bullets Inc. I would use the data from ABC bullets with my XYZ bullets since they are below what the powder manufacturer recommends and at NO TIME would I exceed the powder co's Max load.
