Reloading the .243 AI

[headhunter1111]

I'v been searching the internet and calling all my reloading buddies for the past several days but cannot find reloading data for the 243 ackley improved shooting Berger 115gr. VLD bullets with either H4831sc, H4350, or IMR 3031. Any of you all know any starting loads for one of these combos? I might have to guesstimate a start load based on the SMK 107's and work up slowly or go with a different powder but I'd rather have some solid info going into this deal. Any info you guys could provide would be greatly appreciated. thanks.

I have shot a .243 A.I. in F-Class for a few years now and I have shot both 115 DTACS and 115 Bergers in my gun. They both shot H4831SC. My gun is a Viper action, 30" Broughton 5C, 8 Twist barrel. All I can speak of is my gun and it shoots 46.3 gr. H4831SC. You should start a little lower to test your rifle. I have used both 210M and Wolf primers. Hope this helps.
Remember this is my rifle, I can't speak for any other gun.

My 9 twist Hart barrel won't handle the 115's but shoots the 107 Sierra's lights out. My load is 47.5 Gr's. H-4831sc behind a 107 SMK's using wolf primers and Lapua brass. This load is right at the upper limits so I would probably start somewhere around 44Gr's and work back up slowly. H-4831SC should be an excellent powder to start with as it gives me the best combo of velocity and accuracy. Good Luck.

Thanks for the data fellas. I've got the Beger's and some SMK's that I would like to work a load up for so i appreciate the input. Guess I'll go fire form some brass and load a few up!
