You can at least load them, don't have to shoot them all. I like the 243 & have loaded bullets from 55 grains to 95 with it. I use H-4350 for the 95 grn, mid-weight is usually Varget, or RL-15. I have had great results with H-4895 with bullets 70 grains & under.
I have some 4350 but I'm trying to get my hands on some Varget for the lighter loads. I have over 1000 55 to 70gr projectiles and no powder. I will use the 4350 for 90-105gr loads. Will get back to the loading bench on Friday.
