I went and did it. I ordered some Nitro's straight 7's for my daughters 20g Nova. The H276C's. 1 7/16oz of 7's should put me in the ballpark of 502 pellets according to Nitro's. I wanted to get a little more performance out of her 20. Last year I swapped her Indian Creek .555 for a Indian Creek .570 and now I will have to wait 2-3 weeks to see if this will be a noticable improvement. I patterned her gun last year @ 40 with the .555 and heavy 13 1.25 oz straight 7's best was 140 something so we'll see how this load and choke combo plays out. I'm hoping to pick up a few extra yards for her. We'll see?!?!
You might be crazy I don't know , but not for ordering Nitro 7s you will be pleased I think .
I am curious as well to see how this gun responds to the IC .570 as well. I am going to first shoot some H13 7's to compare, before the nitros. Does anyone here run a .570 IC in the 20?
