I'm just shooting a 38S Turbor, no holes for the past 4 months with MG 124s. I finally ran out but had 1k of 115s laying around. I loaded about 100 to see if I like it and I have to say I can track the dot a lot better than 124s. Also the gun doesn't seem as "sluggish". I shot a match with the 115s last Sunday and really liked it. I'm using 8.6gr of N350 but i haven't chrony it yet. I'm sticking with 115s from now on.
