Currently living in Wisconsin and looking to develop a .223 load and .308 load before crops are planted in Spring.
I'm aware that I'll see different pressures and velocities, trajectories, etc. as the weather warms up and need to be careful accordingly, as well as get new dope during the spring and again during the summer.
It will likely be in the 20s whenever I go shoot to work up a load. I can do this from my back porch so I do have the ability to leave the ammo inside and bring out 3 rounds at a time although obviously the gun will cool down rapidly in between sets.
My question/concern is: Will the load chosen at 20 degrees still be the best load through the rest of the year? Or at least close to it? I'm not a competition shooter so it's just a hobby and I'll mostly shoot my bow while the weathers warm and corn is up anyways.
I'm intending to mix/match Saterlee and OCW a bit and shoot 3 round groups at 300 over a chrono to select charge weight, then play with seating to tune. Mainly relying on Saterlee as the magnetospeed has the potential to affect POI. I know there's other ways people do it and am open to suggestions but that's the way that made sense in my head. Rather than selecting the middle of a node I'd probably stay at the lower end of a node as these temps are the coldest I'll shoot at (and the .308 will be for a November mule deer hunt anyways).
Thanks
