I am working up loads for my 243 that I just finished up building. I have a McGowan 24 inch barrel with a 1-9 twist and I am thinking about 80 to 100 grain bullets for deer. What powder do you guys use I am thinking IMR 4350 or H 4350.
 
I've had a lot of luck with IMR 4831 shooting 95-100 grain bullets. My brother and I both started w/ 243s, 100gr partitions and IMR 4831.
I'm on my 3rd barrel and each one I've lucked out with IMR 4831. Tried H4350, H4831 in all the barrels and just couldn't find anything.
My friends .243 shot H4350 really well.
