In a way these 7 mag threads are a lot like the "which powder in a .223",as with the powder and results posted It is not very hard to get a 7 mag to shoot under an inch, I have tried them all and have come down to what is the least temp sensitive, at least when its in the below zero to 20 above range, H1000 is very accurate but I really have to step on the load to get fps, the RL19, 22 and 25 are very fast and accurate, but I guess I have read into to much temp flex, so it goes, but more than anything this is just a big plus for the 7 Rem. mag I reckon, so Retumbo is my go to powder for now.
