243 powder

I have. 45 grains of it works well in my gun with that bullet weight.
 
Around 39g of IMR 4064 is magic with a fed 210

I have shot many thousands of rounds with Win 760, H414, and my favorite now is the AA2700 as it has one of the lowest heat indexes of any powder made which equates to long barrel life, unlike Varget and IMR 4064.

My brother shoots H4350 with a 9 1/2 primer, consult Nosler's most accurate load.
 
Varget is my go to powder in any cartridge from the .308 win family of cartridges.
That said, I have had surprising accuracy with H4831 in .243 win with lighter bullets.
 
I found great accuracy with 40 gr of Imr 4895 and 70 gr speer tnts. Not the fastest load but shoots well under 1 in groups. I have used this on Montana pds out to 600 yds.
