Re: sst bullet
Harv, I am a big SST fan and would recommend them for your application. You may find that the actual BC is a lot higher then print.
From my '06, the 165gr SST fly 16min flatter out to 1000yds then a BTSP interlock. Same gun, load, brass, everything. Muzz vel 2700fps. Run that thru a Ballistic program..bizarre.
The SST are a "tougher" bullet then the BT and equally as accurate. Have shot groups under 1/2MOA at long range (ie 3rds 1/2" group at 250yds).
