I started with Ramshot TAC several years ago for 6.5 Grendel. It fit the bill in every way (costs$$, velocity, flows like water in a progressive press, pressures, etc.). I still burn some IMR, H, and WIN powder, but I find myself leaning more towards Ramshot and Shooters World stuff. I know Shooters World is hard to come by right now, but I stacked it pretty deep a few years ago. SW Long Rifle is pretty good if you find it, and really actually cheaper than Ramshot Powders. I've had good luck with it also in medium size cartridges. Their Tactical Rifle is supposed to be remarkable, but I have yet to test any. I love the Auto Pistol and Clean Shot!
These are the reasons that I suggested Ramshot Hunter earlier.
