So last week I gave some 27gr Nielson slugs a try. It was very windy gusting to 20mph out of the 7 O'Clock my RW HP in 22cal was sighted in for 25gr JSBs Redesign pellets at 100 yards. My very first slug was sent at a starling that landed on the 100 yard sight in tree out back. Held on the left side of the birds head and watched it fall. All I can say is these slugs work and buck the wind very well. The JSBs required 1.5 mil hold for wind. I am getting 890fps with the 27gr .217 dia slugs. They are amazing to say the least, next will be a programmer to get them up to mid 900fps. Just wanted to share for those RW owners out there thinking of trying slugs.
