I guess that I will need to carry both of them around, the .223 with some mixtures right now of 52,53,55gr HP, SP and shoot up the 100 rounds or so of them and then then .243 with a bullet in the 90grain mark for it.
I am still looking for an article concerning load development. talks of starting out at the minimum load working ones way up to maximum load watching for pressure signs and such. Talks about, say 40 grain first load for 5 -10 rds, then jump up 5%, until max reach. Then examine all of the targets. When shooting these, you just shoot them and then you take them home to examine them. You look for stringing, closure of groups, From what I remember, there will usually be a couple of 'good' loads, or decent rather. Then you load each of the 3 but you will have a total of 5 powder charges for ONE decent powder load. LIke 33grains good. You load some at 32.0, 32.5, 33.0, 33.5,34.0, one can use .3 or .5 in the workup. Small total weights use the .3 and the larger cases .5gr measurement. Shoot them and take them home and measure them out.
I almost have a reloading bench to take to the range but don't want to show off my butt there. Of course when you start working on tweaking the OAL, it would be easier to take the bench to the range for this.
Can someone point me in that direction?
