Did a bit of testing with my Daystate Regal .22 and found out it only likes the H&N 20.2gr, .217 slugs.
Since I can't adjust the Reg and hammer spring of the Regal easily like my Impact, I was limited to shoot certain types of slugs. So I tried the lightest slugs, 17.5 - 23gr of both the NSA and H&N. The Walter barrel is choked and the feed was very tight with the .217 but surprisingly the H&N 20.2gr gave me the highest group of all. I was able to print a 1/4" hole with 5 shots group at 30 yards. My next test is to shoot at longer distance to see if this slug is "the One".
