I experiment way too much with my hand loads... if I chose 1 bullet, (weight / shape) & 1 powder type / weight, I'd have much more accurate shooting results.
As I have a variety of pistols that shoot a particular caliber, I like to experiment.
Different bullet weights, shapes. For example, I load 115gr., 124 gr /125 gr. & 147 gr. bullets in my 9mm.
When I go to the range, I'll take several different weights of bullets, maybe different bullet shapes.
Then see what I shoot most accurately in a particular pistol.
sometimes I do "tests" , like the comparison I posted about my 380's..been thinking of re-doing that with a different load of ammo,
lighter weight bullet, different powder charge.
If my record keeping were better, I'd have some interesting data, re: which pistol shoots which shape / weight bullet best, @ what velocity.
I like truncated cone bullets, but also load Rn pills, also load some FMJ & JHP's of a variety of weights.
For 45's, I prefer 200gr or 225/230 gr. pills. I prefer cone shaped bullets but load RN & SWC's as well.
I started hand loading with Hercules line of powders.. Bullseye, Unique, BlueDot, Red Dot., & 2400
After several yrs. switched to using nearly all the A/A line, #'s 2, 5, 7, & 9..for about 25 yrs..
Found the A/A powders were cleaner burning, also gave as good ,or better accuracy in my loads.
Several yrs. ago, I started using Shooter's World powders.. I like them even better.
Use their Clean Shot, Auto Pistol, & Ultimate Pistol powders..but alas, I can't find them FS anymore.
Like their rifle powders too. Bought 1 # containers, & by the time I actually loaded some ammo with these new powders,
and then got around to shooting the loads & finding out how well they work, no one has any for sale.
my loading & shooting pattern may seem full of variables..I recognize & accept this, ever heard the saying, " variety is the spice of life ? "
