Check out www.handloads.com for 243 wssm loads found good info there most info from hodgson , and found most loads to shoot better lower (slower) than max loads , a good place to start for me , varget works real good i like that powder have fun and good luck :grin:
I did some test with varget when I first got my browning 243wssm. Started at 43gr and went up to 48. I found 55gr Nosler BT shot best for me at 47.5gr.
