I use 46gn Vit N160 in my 21" 1-9 walther barrelled sako with the 75 v-max. Haven't chrono'd yet, expect about 3300 based on when it was a 243win. Lapua cases Fed 210GM primers, ~5thou off the lands. About 1moa. Cheers, Mike

Try Win 760

While aout the burning rate of IMR 4350 and others in this class the 760 seems to like the 243 Ai case. Accuracy in my Cooper factory 1 in 10 has been excellent with the 75 A-Max.

Lapua brass and Federal 210M's of course... work up and enjoy the redmister.

Try VV-N150, H380 and H4350. I would suggest the VV-N150, it's awesome powder. Here is load for you to try;

1. Lapua brass
2. Federal 210M Primers
3. 45grns VV-N150-Work up to this, so start out with 43grns and work up to 45grns.
4. 75grn V-Max

Try the 87grn V-Max too, it's a great bullet. Try this load;
1. Lapua Brass
2. 46grns H4350-Work up to 46grns.
3. Federal 210M Primers
4. 87grn V-Max

If you have a 28" to 30" barrel, you should be able to push the 75grn V-Max to around 3700fps. My buddy uses a 6mmAI with 30" 1-10 twist barrel. He pushes the 75grn V-Max at around 3800 to 3850. The 75grn V-Max is absolutely devastating on Squirrels, Groundhogs and PDogs.

I either use Ballistic Tip's our V-Max bullets for my varminting. They work well out to around 800 yards. I love pushing a Ballistic Tip or V-Max bullet at super high velocities. The splat factor is awesome!

The 243AI is an awesome varmint cartridge. Have fun with it and let us know how the load developement works.

We just stumbled across an interesting load for our .243AI and the 62gr Varmint Grenades this weekend. Turns out 51.5gr of H414 will push these little guys to 4030fps out of a 27.5" 1:8 barrel. ES and accuracy was very respectable as everything from 50-51.5gr all shot in the same hole.

That which does not kill me......has made a huge tactical error

Re: 243 AI 75gr vmax loads

I usually use AA 2700 for my 10 twist 243AI shooting the 70 grain blitzkings & Hornady 75 grain V-maxes, but I have used H-414, & W 760 all with a Magnum primer to lite it off...
This day the 243AI got me into the 500 yard club.
Hoggin' Heaven'... That's where they are when I'm done!
