I've been reloading for a while now. The 243 Ackley Improved is my first wildcat, though, and I'm looking for tips on where to begin. I have searched the interwebs and read lots of articles and threads on the topic and have made records of lots of other folks' pet loads. That's given me a good idea of preferred powders.
Many seem to suggest that one start with max loads for the .243 Win and work up from there. Others have suggested that one can use 6mm Remington load data as a starting point, as the case capacity of the .243 AI and the 6mm Rem are pretty close. Does that sound right to you?
I am building a lightweight hunting rifle, so will be working up a varmint load (55-70 grain bullet), as well as a heavier medium/big game load (90-105 grain bullet). Rifle is a Remington Model Seven with a McGowen "Remage" barrel, 20-inch, 1:8 twist, light sporter profile. I have lots of .243 Win stuff to play with--IMR 4320 and 4350, H4350, Varget (off the top of my head) and a good selection of bullets from 58 to 100 grain. Mostly interested in your feedback on the idea of using 6mm Remington data as baseline. Thanks.
