) Patrick didn’t expend time looking to tune a load, due to the fact genuinely we had been trying to maintain the load as being the set variable as well as temperature since the unbiased variable. I’d guess the outcome would search pretty similar regarding muzzle velocity spread, Even though you tuned Every load.
