This is probably the millionth thread I've made about the 243, but I was recently steered towards H4350.
105 AMAX, Winchester Cases, COAL 2.75 and another at 2.825 (trying different depths).
So my question is, what are you guys starting, and ending at?
Thanks!

Tanner - I start w/bullets as long as possible in a magazine that allows feeding/chambering and unchambering in MY gun w/o leaving a bullet stuck in the bbl.
Long ago I used 41/IMR for 100 PTs....
If I was running H w/Amax, I'd start at 39 and try 39.5 and 40 stopping there unless pressure seen before 40.
243s are not hard to make shoot, assume you have a 9" or faster twist? FWIW I have a 9 twist 20" and using RL19 put 3 into like 1/4"...it's a shooter...

I'm going to start at 39 and just work up, I think that's a good place to start. I've seen guys go as high as like 42-43 grains.

Retumbo and 105's are a match you will not believe! Use fed 215's.

4350 is a good powder but in the 243 Win IMR 4064 is my go to powder and has always give me the best accuracy
