I've just acquired a 7-STW and have no prior experience loading for this round. Anybody have any helpful hints or good starting places? Right now, I'm favoring RL22 or RL25 and medium weight bullets. Maybe the Scirrocco. Which IMR powders do well?? 7828?? Just looking for any info I can scrounge up.

With the 120s I use a heavy load of Rl22 For the 140s I use a heavy load of 7828. I haven't tried RL22 but it should work great.

For 160's give Hodgdon's Retumbo a go. Also Ramshot's Magnum has worked real well.

I'll second the Retumbo recommendation. Also have had excellent results with H5010, but this is only useful for bullets of 160 to 175 grains. Enjoy your STW! A very specialized chambering, but great to have when you need it. [Read wide, open spaces] Regards, Eagleye.

83gr RL25 behind 140 Nosler BT. It'll work!!

I like a healthy dose of r25 and 160 grain accubonds. I couldnt find any 140s that would group all that well. good luck!
