The NSA slugs .249 Cal that I have now (29 grain) fit loose in the sidewinder.25..... No accuracy at all.... Need to try the 34 grain that are .25 exactly.
The NSA slugs .30 Cal that I have now ( 43.8 grain) fit ok, but I need to play with fps to get to know how accurate it is.
What I can confirm right now is that:
Sidewinder .25 is very accurate with the JSB's 34 grain at 865 fps, close and at very long range.
Sidewinder .30 is very accurate with the JSB's 44.7 grain at 850 fps, close and at at very long range.
With the same configuration, my Vulcan 3 500 mm in .177 Cal, my Uragan in .22 Cal., my Vulcans 2 in .25 Cal and .30 Cal shoot perfectly well both , the pellets and the NSA slugs I have.
