@kingmt, that's very true. Varying environmental conditions can change things significantly enough on their own. Change the temperature from a cold winter day to a warm summer day, and it will behave completely differently.
For right now, I'm just shooting indoors on a climate-controlled range. But, I'm curious how it'll behave outdoors in different temperatures. I have a friend that knows a good outdoor range. I'll have to hit them up to do some testing.
@Hokie_PhD and
@ajandrs, thanks! It's been fascinating learning to reload. There's so much going on, and so many tiny variables that can add up to the result we see on paper! I'll try to stick with the (mostly) basics for now and see how far it takes me. So far, my regimen includes hand-cleaning and lubing cases. I hope to switch to a wet tumbler soon. I've also taken once-fired brass and uniformed the primer pockets with the uniformer from Sinclair, and I've deburred flash holes. I want to take as many variables out of this equation as I can.
As for powders, I'll probably only test one or two at a time until those run out. I have a couple of good loads for the two that I have (Vihtavuori 140 and Varget), so I'll use those up before moving on to something different. Next up, I want to try some lighter bullets. Maybe something in the 64gr range, and something in the 50-55gr range, just to see if I can get them to shoot tight groups. I'll probably try the Hornady V-max bullets and go from there. It would be nice to have something I can use for hunting/varmint purposes, and not just all target rounds. Plus, I hear the V-max bullets are quite accurate.
Other bullets on my list to try are: 55-65gr Sierra Game Kings (that's as high as they go in .224 diameter), 75gr Hornady ELD Match (if it even makes a difference over the normal Hornady Match bullets), maybe even Barnes TSX to work up a hunting round (though, at $30/box it could get pricey doing testing...). And I have a few powders I'm interested in, also: BL-C2, H335, TAC, CFE 223, etc. But, I'll grab one at a time and work up a load. I still want to look at reloading for pistols, too.
I both love and hate trying out all of these combinations. It ends up being fun, but also expensive working up a single load that works well for one powder and one bullet. So, I need to spread out my testing and costs over time to keep from spending too much at once.
