what bullet are you planning on using ?
it's been many years since I loaded for the 243 . I used IMR7828 , before IMR7828sc was on the market . I found the 100 gr partition to be my bullet of choice , for whitetails .
If you have the bullets you want to use , and the powder you want to use , about all you can do for less recoil is go to the min starting loads of powder . the most common way to lower recoil is lighter bullets , and going to a reduced load of powder . faster powders will lower recoil too ...
use the Hodgdon H4895 reduced load formula . you can up the powder charge to where the recoil is acceptable . the 60% reduced minimum loads , are usually very very mild .
