Also, one major thing I would add for shooting the 90’s from RMR is some lots are pretty consistent, but if you mix a few lots of say 500 there can be almost .5 grains +/- on a few bullets. If you are just plinking at 1000 it is what it is, BUT if you are shooting a competition where you NEED to eliminate as many variables as possible I would 100% weigh your bullets with a super accurate scale (I use the A&D120 that measures down to the .02 (2/100ths) of a grain. I keep my batches in roughly .06 +/-. Last thing you want at 1000 is one round weighing 89.70 and the next at 90.26 grains!!! That will translate to about a 3-5ish MOA elevation change on target.
