Thank you so much for your response. I'll pick up some new orings and lube for the valve rebuild. Where else should I apply the lube besides the orings? I'm assuming your barrel is 1:26 twist? If so, you gotta try the Varmint Knockers 50gr and 62gr. They shoot the most accurate from all my testing. With the 28" barrel I strictly use the 62gr since it has the power to push over 1000fps. When I had the 20" barrel I used the 50gr.You should be sub moa with these slugs.
This is how the custom 30cal marauder sits now.
