Thanks Varm.
I read an article not long ago and si snipe was using 147gr ELDM's in his 6.5x47 and I think he was running about 2770fps on or very near 41grs of RS62..
Nearly 200fps down on somebody on this thread was getting 2960fps I think on 46grs of N160 in their creedmoor 😳.
200fps is a huge difference..
This may see a pressure spike on a warm day 😅
