THE HANDLOADING BENCH
6mm NORMA BENCH REST (Part 5)
However, go onto that invaluable resource for the 6mm BR (and BRX / Dasher) shooter, the onetime
6mm.com website now renamed AccurateShooter (

Norma 203B, and IMR-4007ssc. One notable feature is that unlike QuickLOAD, not a single ball-powder makes it into the list, although there are some in the lighter bullet ‘Varmint’ loads.
The easy way to make the cartridge perform well in most rifles with 87-108gn match bullets is to use Lapua brass, a CCI-450 primer, and VarGet. That’s not to say lots of other powders don’t perform equally well or even better in some combinations but VarGet seems to be particularly well suited to this package. This can present difficulties of course when we suffer

one of our regular VarGet ‘droughts’ as applied to most of 2010 in the UK – suddenly forums were full of anguished requests for sources of the powder (fat chance!), or alternative load and data suggestions for Vihtavuori and other propellants.
I like VarGet in 6BR with 95-105gn match bullets, have used it in my match loads for three or four years and shot my smallest ever group with the 105gn Berger VLD over this powder, that is the smallest group I’ve shot with any cartridge, not just 6BR.
Next month, I’ll cover my experiences with match bullet loads to see if we can find other powders that work too.
