So , got my new Maverick started testing .30 cal slugs fx hybrids 44.5 grns at 905 fps, a bit low and the First Reg was 150 and the second reg was 130...
Much of the information out there suggests shooting slugs at regulator pressures around 160s to 170s and second regulator about 150...
So thats pretty much what I did with the maverick, Set up the first reg to 165ish and second to 150ish. Went to chrono the gun and BAM speed is 830 now.
I thought well I can turn up the spring tension to hit the valve harder and let more air out. I tried spring tension from max all the way down and it appears the velocity is not really changing and in fact going down into the 700ssss sometimes. I think I have the reg pressures too high which is a bit of a shock..
So new solution which I question is to degas the gun, Set first regulator to 155 to 160 bar and second reg to 140 bar ? hmm any error in my thinking ?
