The Hornady book says it's usefull velocity is from 1600 to 2600 FPS and I see in the Ruger #1 they got up to 1700 FPS with under the Maximum load, so up close it may be fine, but farther out you may lose too much speed. I have gone on their website and asked questions about their bullets and they have replied with the info I have asked before, so you could try and see what they say based on what your rifle produces velocity wise.
