Hi mate 43grns of Vit 140 for 58grn Vmax 2.602 oal, gives 3800 out of 26" tube with a 1-10 twist using fed gold match primers and lap brass.

tried it 5 243's over the years and its worked in each one,

Sorry cant help about the 308 but Varminter will be able to help you there.

Yes Vit 140 will do it all.

44.4 grs behind a 165 hp sierra gives good results in my 308.

38.5 grs behind a 85 gr in my 243 is my usual and as nemasis said it will run the 58 grs ok.

I would have thought W748 was more appropriate.

760 is def better for heavy bullets, eg 100/105s in .243 and 180+ in .308s

 

748 is the speed king in long barrelled .308s shooting 155s. 3000fps is def do-able but it's considered as a less-than-accurate load at shorter range (under 500yds) by my very experienced clubmates
