If you have an old pair of jeans, you can make a decent shooting bag for the front rest. My wife made me one when I want able to buy what I wanted.
For the platform you have described, I wouldn't hope for much better than a 2" group.
If you were getting soft ball size groups with factory and cut it down, it is an improvement.
You can use a piece of pistol brass with a piece of wire spun around it as a Dipper to help measuring charges.
One other thing, what scales are you using and is there an air duct near it?
