I have loaded for a lot of .243s. starting in 1968.i have had great results with 4064 and varget and 85s , also 88 grain bergers. I 4350 and 100s. and i4350 and 95 partitons. the 95 grain bergers shot poorly out of the sakos and remingtons we tried. for long rnage hunting we us re-26 and 95 partitons in sakosand Remington. I have never tried the 105 Hornady out of anything but my 8 twist 6mmbr with Krieger barrel. of course they shoot very very good as do the 107s.
