Re: .243 Load / Bullet suggestions
I have loaded for several .243's ove the years. Most were of the 1-10 twist.
This said the same powder that has worked time and time again for velocity and accuracy has been H-4350. I have loaded mostly with 90-100gr bullets, and it just works. I mostly use Winchester cases, and have never had much of an issue with them as long as I kept the loads sane. Start pushing them and you will get thick necks and other case issue, but within standard loads they are about as good as any.
Mostly as of late I have been shooting the cheaper Remington CL's, Hornady SPBT's and the older Nosler Solid Base which I have a decent rat hole of. THe latest rifle I have been working with is a Sako Forrester, and it has shown remarkable accuracy with the Noslers. My friend who also shoots one of these is working with the Hornady's. For now my load is using the newer Hodgdon Hybrid 100V, and velocity and accuracy have been outstanding. I cannot however say that it will be any better than the H-4350 loads I used in the past as I haven't had the chance to work up with it just yet.
For primers, the hottest you need will be a Winchester LR, and I have found as others that the CCI-BR2 is a good one as well. Not that others won't do good, just these have done better overall than the others.
Good luck and hope you find your magic load.
