My favorite load from my 243 bull barrel..is using Remington cases..Remington 9-1/2 primers..and Reloader 22 and 95 grain Combined Technologies bullets
You can see the powder amount in this pic..It's a max load for mine.. and I loaded 4 different loadings for it...shooting all 4 5 shot groups in under 3 minutes... so..do as I did...Load in small increments watching for pressure signs...and enjoy
Merry Christmas to you as well
