Like mentioned run some more through it, and see where your at.
It usually takes me close to a year to finalize a standard load for a particular rifle. I usually try and start in Jan or Feb when its cool so I don't have to wait on barrels to cool off, but at this point I am simply looking for groups. Not that I shoot it every weekend, but I will play with several powders and bullets and primers, and this takes time. Then go back and pull the best data from that and go again during the heat of summer, possibly playing with seating depths, then working the final loads through temp changes to see if any do change. This keeps me honest and allows me to see how much the temp change from cooler to hotter weather plays on the loads. At times I have found I could not work back to where I was with a load, once the temp got up 30 - 40 degrees or more warmer. Once done however, you have a load that will work out year round, and your set.
It's not like this takes shooting umteen hundreds of rounds, if you already have a particular powder and bullet combo in mind, but it narrows down the important things that can and do sometimes sneak up and bite you in the rear, just when you least expect it.
