I've used it and the IMR version, mostly with 50 grain varmint bullets.

Gave up a little speed but had damn good accuracy. 22" bolt rifle was getting 3200 fps with 50 grain Nosler.

I shoot the same load in my ARs, OAL is change to mag constraints but a good shooting load, noticeably better than 55 grain fmj but that's probably due to the bullet more than the powder in that comparison.
