I have a SA 410 and Tried the Jebs XX full, IC 385 and the Primos 390. My gun shoots best with the Primos 390. I was finally able to get a IC 390 so I am going to try it. I also bought some 383 Strokers 9 1/2's and the 1oz load of 10's. I hear between 190 to 200 bb's in a 10 inch circle at 40 yards with the 10's.
