True Blue is the only Ram Shot powder I've used and I like it a lot. I've used it in 5.7x28 and many 5.7 reloading "experts" will tell you it's hard to beat unless you stocked up on HS-7 before it was discontinued. I've also used it in 9mm and .45acp with very good results. Accuracy was very good in both, it was clean burning, and recoil wasn't bad even on the high end. It's a ball powder, which if I remember right all Ram Shot powders are so you can expect good metering from a powder measure. 5.7x28 is a tricky caliber to reload for and it's good practice to weigh out each charge for it. Every drop from my Hornady powder measure came out perfect, no trickling. I can't say that for any other powder I've used,, even with there's other ball powders I've used I still run into a .1gr variance from time to time. My only complaint is Ram Shot powders aren't too available locally and while they're still cheaper than most of the competition but I've noticed the prices have gone up about $2/lb when I can find it.
