I currently have some Norma brass which I only use with the Hornady 139 and154 grin bullets. I also have some Selleir & Bellott brass, which is purely for the Woodleigh bullets. The S&B brass is 2 grains heavier than the Norma, so I've worked my loads up accordingly. As I've said before H4350 is the only powder I'll use. I'd like to try R17 but supply is a bit erratic down under, and I have heaps of H4350. I'm playing with the Woodleigh bullets mainly because their 140gn 7mm bullet is very well constructed and will give better penetration on larger deer like Reds and Sambah. For the most part I'll stick with the 139gn Hornady SST. I'm getting 2,800fps with them, and the deer and pigs I've hit with them have never complained.
