As to how accurate they will be.. only your rifle knows for sure. Like Roscoe said, don't push them hard. I like to start them with 80 grains of powder. That is more then plenty for ranges under 100 yards on deer. If they group good, you're in luck. Don't push them more then 100 grains.

There are lots of different conicals out there you may want to try. Under someI run a wad and some I don't. All you can do it try it both ways in your rifle and see what works best for you.
