Thank you guys for replying. Don't worry, I take responsibility for my own actions with regards to loads etc. that I read on this post. CptCurl, that is a great group. How was RL-15 doing compared to this with regards to left and right barrel groups? I find good barrel groups but the left seems to be two inches to the right of the right group. My speeds are the same as what it is regulated with.(IMR-4831). I have tried lower RL-15 charges and the groups are even worse, not to mention the velocity.

500grains, I am looking forward to your results with this load.
