I am looking for a quality company to do load work up and development on my custom rifle, it seams to shoot better than I can already. I have only played with one bullet and a varget charge to break in barrel and am getting 1/2" to 3/4"

Check them out. They offer this service, but I have only used their ammo.

.5" to .75" with your first attempt is quite good, BTW.
