Yes the sst is in 243 also,just ordered a box to try day before yesterday,(100gr or 95 gr. some catologs say 100gr some say 95gr.)
I have been shooting them since they came out,took several deer with them in different cal.They work great in my 260,7/08,280,and 30/06.From 45 to 200 yds never had one to stay in the deer all complete pass throughs even shoulder hits.Have used NBT also and they worked great too,but I get 50 more bullets for just a little more money.
