243 Win. load suggestions?

[Clark]

I was necking LC brass from 308 to 243.

I shot a 243 Win for several years, mostly at 600 yds., with 105 Berger Hybrids and H4350, which gave me about 3,190 fps from a 28", 8 twist barrel.

Don't use 308 brass necked down. It may pinch the bullet giving a wide range of pressure.

Did you trim to length and turn necks ?

I did not turn the necks. That is probably the problem. That was in 2002 and my first reamer and some of my first reloading. I have since learned about turning necks.
