Favorite 243AI loads?

[holstil]

Interested to see what others are using for 243 Ackley with 105-108 grain bullets. I'm hoping to find a load around 3200 from 26" barrel, but need accuracy.

Thanks, jim

I run H4831sc with 105 gr. Berger's at 3095 fps Lapua brass, in a 26".
I can get more speed but this is the best accuracy for me.
There is a section at the top of this page with a bunch of 243 AI data.

R#26 will get you to 3200+ in a long barrel

RL-23 will get you to 3,200 comfortably, too. RL-26 will get you quite a bit more without pressure.

RL-23 is as insensitive to ambient temperature as anything I've ever seen. If you're loading for string shooting, this may be an important consideration.
