I just finished building my 243 AI and I am looking for some help with load data once the cases are fire formed. I have an 8 twist 24 inch barrel. I have both the 75 and 87 grain v max to play with. If anyone has some load suggestions I am all ears. My preferred powders are h4350, win 760, h380 and h4831sc. I have many other powders but if you have load data for any of those powders I would prefer those first. Thanks for helping.
If only hogdon included wildcats or variants. Anyone have some data please ?
With ai cases I am pretty sure standard operating procedure is to start near max for the standard loads and work up in .5-.3 grain incriments. That's the fun part of using wildcats. You get to experiment and find the load that is unique to your rifle.
When developing a load for any improved cartridges I always start with an upper middle range load for the parent cartridge. There are just too many variables to say what load will work, is the best or even safe for your rifle.Originally Posted by colt56
BTW, if you don't have a chronograph get one. With it and the targets they'll tell what your rifle likes.

With 75gr bullets I run as much 760 as I can fit in the case, and the same with 87gr bullets and H4350.

RUMs are like woman in Stiletto heals, you know they are going to put you in the poor house, but that has never stopped anyone from pursuing them.
