My son just bought a Savage 243 model 110 I think, and he is in North Dakota and plans on using I double duty for coyotes and antelope. I have dies and brass so am gonna load some up and try them in my Sako and hopefully they will be ok in his rifle. I bought some varmint bullets including a box of Barnes 70gr Varmageddon. I went to Barnes website to see if they list "most accurate" powder or any load data and see that their on-line manual wasn't updated since 2009 and they don't even list the bullets I bought. I can figure a starting load with various powders and start from there, bought thought if someone has any experience or a favorite load with these in a 243 it might save me some time.
I've got Varget,H414,4350,4831,RE19 and some other powder that should be appropriate.
Any thoughts??

I just loaded some 70 grain hollow point's with 41.6 gr of vargets in the lymens 49th edition Max load is 41.7 ,shot 5 rounds through my encore and it loves them .
But from what In have been told about Barnes is they have to be loaded a little liter than other bullets .
I would maybe start around 36 grains of Vargets and go from there

41.0 grains of Varget has shot extremely well in a couple of my .243's with 70's. Also had great results with 42.0 grains of the new IMR4166 in one rifle.

51 gr of Superperformance will push a 70 varmint bullet @3600 +
48.7 gr of Superperformance will push an 80 TTSX @3400 +

both with less PSI than a 270 WSM.

The 80 gr TTSX is very effective (this one in .257), bang flop.
In behind last left rib out thru right shoulder.

Varget works in both of mine, but most consistent velocity and accuracy was with 38 - 39 grains H-4895 with 70's and 75's.

I like Varget and W760 in my .243

Thanks for the replies.
I was thinkin Varget would be decent and since I have some that's where I'll start. Don't have any Superformance or the new IMR4166.
Miss the days when I could drive to local gun shop and buy a pound of xxx just to try it... sigh
