I have a Benjamin Cayden in .22 and want to get some of the NSA 17.5gr slugs.What would be the best size to try .2155, .2160, .2165, .2170 or .2175?Also do you think the hybrid slugs would shoot better.
Like so many have stated, buy the sample packs and try them. I have a Daystate MCT .22 shooting the 17,5 gr and it loves them. I have tried all of the sizes in the 17.5 gr and the .216's and .217's shoot great but the .217's go into the barrel really snug. I settled on the .216's and my rifle is shooting them at 916 fps on High power.
