my project, I want a 100gr or so bullet, to travel at 900 to 1500 fps suggestions?

IF you are talking rifle in the .30 class, 13 gr. Red dot will do the trick. For anythig else, we need just a LITTLE bit more info! :0)

i have a 308 but never used light loads like that. i need a light ang low noise bird gun but with a bit more bang than a 22lr
