7MM Rem Mag "cat" load

[Jim]

I'd like to work up a very light load for a 7mm rem mag. I found 100 gr. hollow point varmint bullets. Any body here got any data or experience with ultra light loads for this caliber? I'm thinkin' Unique might be a good powder. The object of the game is to get the bullet up to about a K FPS and hold it there.

Thanks,
Jim

I've had good luck using Red Dot for applications like that. It's big and fluffy, and lights really easily so works with lots of air space. I'd think Unique qould be a bit slow burning and hard to get any accuracy with it at the 1K level, more likely closer to 1400 or so.
