243 AI Load Data ???

[Chuckhunter]

I am currently building a 243AI on a Wichita Action using a Hart fluted 9 twist barrel in a McMillan HV Stock. I plan on using 87Gr Hornady V-Max's and 95 Gr. Berger VLD's to start with. I would like to hear from anyone using these particular bullets, regarding powder selection and loads that have worked well.

I have a Rem .243AI with a 1-10 twist for the 87 Gr V-max's and it shoots very well with IMR4350 Winchester brass and Fed 210's. My best groups come at about 3400 - 3450 Fps.
My Winchester .243AI has a 1-8 twist and shoots the 95Gr bergers best with IMR4350 the same Win brass and Fed 210's. The 95's group best in the Win at 3300-3350 Fps.

Be sure to look at the .243 info page

They recommend H4350, and H414.

I just picked up a .243AI. Nobody had 4350, or 414, so I picked up some Re19. 47gr of Re19, 87gr VMax, Lapua brass, Fed GMM primer shot very well with no pressure signs in my rifle. I'm going to get some 414 and 4350 and try them as well. No chance to chronograph the load. Maybe tomorrow.
