VV N340 Fireballs.

[Germz]

Went to Camp Pendleton range today with a bud. I was shooting 124gr lead RNs I made with 4.7gr of Vihta N340. Not sure if it was because I was outside or what but Jesus that load (minimum load per lapuas website) shoots fireballs. Never seen it before. what causes that? too hot of a charge or what?

What was your OAL?

[Germz]

1.150" as always.

[HighLander51]

how long have you been reloading?

I bet it's the grains to grams, the metric to english unit conversion error.

Lapua says that 4.7 is the starting load for 124 lead and N340...

Strange.
