Best NSA slug weight for Red Wolf HP

I was thinking of ordering some NSA slugs (.217) for my .22cal Red Wolf HP with a factory tune and was wondering which weight would shoot best.

Hi there, there are a Few post I made a while back, if I remember correct best NSA are 20.2 and 24.8gn .217 and the FX Hybrids out of the RW HP .22 GCU2.0 (Safari)
 
Agree with Nick above. When I say “better” to me that means the difference between 1.0 and 1.2 inches at 100 yards. You need to try the .218 NSA 20.2 grain in the RW HP.
My .22 EDGun loves the .217 NSA 20.2 and it outperforms the JSB KO by a wide margin in that gun. I also recently discovered that my .30 Vulcan2 Tactic likes the .30 NSA 43.8, and they shoot about the same at 100 yards as the 44.75 grain pellets. So try various slugs in your gun and don’t just take someone else’s word for it...
