Just got my first 243. Looking to shoot the 105amax.

Looks like Retumbo is the go to powder but I have a pound of IMR4350 which has been mentioned before...

Just wondering if anyone has played with it.
 
Re: IMR 4350 and 243?

Yep its the only powder I use in .243. I found 43gr to shoot nice, and I have another load using 44.5gr with a Nosler 105gr CC. However this barrel had the throat REALLY far out, not sure why. I have a new barel coming so I'm guessing my load will be less as I know the load I"m shooting according to the books is over the max, but it was safe and didn't show preasure signs in my gun.
