Just for fun, If you had to shoot as you do, with only 2 powders (rifle and pistol) for targets, hunting, heck, survival in general, what would you want a store of as the most versatile?
I shoot rifle and pistol in numerous calibers....
1. Unique for pistol.....reloads everything pistol ....also I've experiemented with this in several rifles (308, 30-06, 7x57, 8x57, 8x56, 6.5 x55) 11 to 13 grains is so accurate to 100 yds. Good to know in a pinch......11 grains produces 900 -1100 fps in all rifle calibers above (USING LEAD BULLETS ONLY, but I'd feel ok with jacketed in a pinch because ALL spent cartridges were inspected, without any damage and some showed low pressure signs). If I could only have one powder, it would be Unique.
2. I like IMRs....personal taste only, would use more temp stabilized Hogdon's if their data was more avail to me way back then, I'm an old dog (in reloading) and my IMR tricks have served me well. My favorites are IMR 4831 and IMR 4350. But, If I could chose only one rifle powder to stock up on and use for everything, it would be IMR 4895, with 4064 in close second. IMR 4895 does from .223 to .300 Win.
The green Speer #10 reloading manual (late 1970 early 1980s is my favorite ever: pre-lawyer wuss loads).
I like opinions from fellow shooters, what say you?
