I'm' working on my 243 with 70 grain B-tips and have 2 powders to try, Varget and IMR4350. Of the two, what one would you start with?

...I'd try the Varget, don' think you'll get good results w/ IMR 4350 till you get up into the heavier bullets...

I'd start with IMR4895.
The club load was 39.0 grs IMR4895 and a 70 gr bullet. It shot well under MOA in 7-8 rifles.

Yeah I was running 45 gr and it was hot but good load in mine. That 243 kicks like a mule has since day one. Now using H380 Nosler best accuracy load at around 3k groups under an inch without any load work.
I don't find much difference between Varget and IMR 4350 in my rifle. 22 inch barrel gives 3475fps with 47.0g 4350, shoots sub MOA with several 0.4 inch groups. I get 3515 with 42.0g Varget, but the accuracy load with varget in my rifle is 40.0g which shoots 3435fps and sub MOA with several groups at 0.7 inches.
Varget uses 7 grains less powder per round, about the only benefit I see. But I can get ahold of 4350 much easier lately.

Have fun, I am betting between Varget and 4350 you'll find a great shooting load pretty quick.
JD's load using IMR4895 is a good one. Shot it a couple of times in my rifle.

Have fun, I am betting between Varget and 4350 you'll find a great shooting load pretty quick.
JD's load using IMR4895 is a good one. Shot it a couple of times in my rifle.

42gr of Varget was my accuracy load with the 70 BT before the rifle was rechambered to 243 AI.

I use 4064 and H380 for my lightweight bullets and 4350 for the 100-105 grainers.
It's been my experience that most .243s aren't particularly finicky and will shoot most any load decently.

We just tried some Ramshot Big Game with the 70 gr Ballistic Tip and the results were amazing. Max load from Nosler manual clocked an average 3550 fps out of a 22" barrel (Stevens 200), and put 4 shots in under an inch at 200 yards with 3 touching. Sure wish I could find some more, but haven‘t seen any in stores or online for a while.
