357/38 Powder choice

[boff180]

Can't go wrong with Vihtavouri N320 in either 38 or 357.

I use 4.8grns in a .357mag case with a 158grn TC lead bullet - and it will out perform me at 50 metres in my rifle, when I do my part it will single hole at this range.

4.8grns is a maximum .38spl charge for N320 with that head but below minimum in a .357mag. In general, max 38 loads are fine in 357 cases.

I use 4.4 gn of N320, .357 case, 158gn TC lead... as above, one hole at 25, cloverleaf at 50 through my Marlin 16'' 1894

I have a .357mag Rossi. I use 5.0gn of unique with a 158gn SWC

Currently I use 3.4g of Vectan AS behind a 158g truncated cone bullet bought when AS was about £34/kg. Now it's double that I'll be changing to Maxam CSB5 (still about £34/kg) when I've used up what I have left.

I have a Winchester 94 and use 6.5gns unique with a 158gn RNFP; last comp I won with it I never dropped any points at all; my best ever!
